     TECHNICAL FIELD 
     The present disclosure relates to chimeric receptor binding proteins, in particular derived from bacteriophage receptor binding proteins, able to withstand proteolytic digestion, in particular gastrointestinal proteolytic digestion, bacterial delivery vehicles comprising said chimeric receptor binding proteins, and the use thereof in efficient transfer of a desired payload into a target bacterial cell population, in particular after oral administration. 
     BACKGROUND 
     One of the critical aspects to be addressed when considering protein-based DNA delivery vectors, such as packaged phagemids or Eligobiotics®, is their stability in in vivo conditions. Depending on the route of administration, packaged phagemids may be exposed to different factors that may affect their stability and functionality. For instance, orally administered packaged phagemids will have to traverse the gastrointestinal tract: harsh conditions, such as the low pH in the stomach and the presence of certain digestive enzymes, may have a negative effect on the structural stability of the particles. 
     Phages have evolved to be stable in a wide range of conditions [1]. From the evolutionary perspective, being able to resist these conditions is a clear advantage for any phage. 
     However, it is well known that many phages are not resistant to low pH values for a long period of time [1], [2], although this can be circumvented by the use of stomach acid neutralizers [3]-[6]. Similarly, some phages have evolved to be resistant to digestive enzymes, such as those found in pancreatic juices (trypsin, chymotrypsin, etc.), while some others are readily degraded [4], [7], [8] although the exact mechanisms of degradation have not been studied in detail. 
     From these facts, it can be concluded that for the development of a highly successful optimal phage-derived DNA delivery vector, such as an Eligobiotic®, it is useful to obtain a vector which is stable in in vivo conditions. 
     The present disclosure provides a solution to this need. 
     A powerful engineering pipeline has been developed to generate phage-derived DNA delivery vectors with improved or modified host ranges as disclosed in WO2020109339. To do this, the natural variability of phage parts has been exploited to generate functional protein chimeras in existing phage scaffolds: for instance, one was able to modify the tropism and injection efficiency of packaged phagemids by modifying the two main host range determinants of lambdoid phages such as the lambda phage, the gpJ and STF (Side Tail Fiber) proteins. 
     In the course of vector development, it was observed that one had to differentiate between functionality and stability. A given protein chimera (for instance, a STF fusion) can exhibit an ideal functionality, for example can contribute to a high injection efficiency into a target strain in in vitro conditions, but may be affected when exposed to pancreatin (i.e. still functional but less stable). This was an unpredictable aspect of the protein engineering process so far: starting from two different STFs that are not degraded in the presence of pancreatin could yield a protein chimera that was less resistant to proteolytic digestion. 
     Different direct (on the packaged phagemids itself) or indirect (on the environment of the packaged phagemids) approaches can be envisioned to protect these protein chimera from in vivo proteolytic digestion, e.g. a suitable formulation, such as controlled or delayed release formulations enabling the release of packaged phagemids displaying said protein chimera in the intestine or the colon. The present disclosure shows that another solution is to act directly on said protein chimera. 
     SUMMARY 
     The present disclosure is based on the unexpected finding that, by specifically designing a small fusion region (also called linker region) between two different STFs, it is possible to render a chimeric lambda based STF protein, which was initially engineered to be fully functional but was less stable in the presence of pancreatin, both functional and highly stable. 
     It is worth noting that in natural phage STFs, proteolytically degradable residues exist that due to conformation or interaction with other residues/proteins may not be accessible for degradation in normal conditions. However, such residues may become accessible for degradation when these STFs are used to produce chimeras. It has been specifically demonstrated that introducing point mutations in phenylalanine (F) and lysine (K) residues present in the linker region, corresponding to a region of about 10 to 12 amino acids adjacent to the insertion site of chimeric lambda STF-V10, rendered the chimeric lambda STF-V10 protein partially resistant to pancreatin hence with increased stability, while the original chimeric lambda STF-V10 protein was not resistant to pancreatin at all. 
     It has also been demonstrated that designing the linker region to include a short sequence which was initially present at the N-terminus end of the C-terminal region of V10 tail fiber used to produce the chimera, rendered the chimeric lambda STF-V10 protein highly resistant to pancreatin (without introducing further mutations in the linker region). 
     Further it has been demonstrated, in another chimeric receptor binding protein, namely a functional chimeric lambda STF-K5 protein, which was not very stable in the presence of pancreatin, that introducing, in the linker region, the same helix-forming sequence initially present at the N-terminus of the V10 tail fiber, rendered the chimeric STF-K5 protein highly resistant to pancreatin hence strongly stable. 
     Furthermore, it has been demonstrated, in another functional chimeric lambda STF-K5 protein, which was not very stable in the presence of pancreatin, that introducing, in the linker region another helix-forming sequence present within the STF protein of the Escherichia phage ZG49 (which has homology with the wild-type K5 protein), rendered the chimeric STF-K5 protein very highly resistant to pancreatin. 
     The present disclosure thus concerns a chimeric receptor binding protein (RBP) resistant to proteolytic digestion, in particular within the gastrointestinal tract, wherein said chimeric RBP comprises a portion of a receptor binding protein derived from a bacteriophage fused through a designed linker region consisting of 1 up to 70 amino acids, more particularly of 1 up to 30 amino acids, to a portion of a receptor binding protein derived from a different bacteriophage, wherein said linker region is designed to be resistant to proteolytic digestion, in particular within the gastrointestinal tract.

     DETAILED DESCRIPTION 
     Chimeric Receptor Binding Protein (RBP) 
     The present disclosure relates to a chimeric receptor binding protein (RBP) resistant to proteolytic digestion, in particular within the gastrointestinal tract, wherein said RBP comprises a portion of a receptor binding protein derived from a bacteriophage fused through a designed linker region consisting of 1 to 70 amino acids, more particularly of 1 to 30 amino acids, to a portion of a corresponding receptor binding protein derived from a different bacteriophage, wherein said linker region is designed to be resistant to proteolytic digestion, in particular within the gastrointestinal tract. 
     Resistance to Proteolytic Digestion 
     By “proteolytic digestion” is meant herein proteolysis of a protein mediated by an enzyme having any protease activity. By “proteolytic digestion within the gastrointestinal tract” is meant herein proteolysis of a protein mediated by an enzyme having protease activity in any part of the gastrointestinal tract, such as in the mouth, the esophagus, the stomach, the small intestine or the large intestine. In a particular embodiment, said proteolytic digestion is within the small intestine. In a more particular embodiment, said proteolytic digestion is within the duodenum. 
     As well-known from the skilled person, proteolytic digestion within the duodenum is mainly affected by bile salts and pancreatin. In a particular embodiment, said proteolytic digestion is by pancreatin. By “pancreatin” is meant herein a mixture of pancreatic enzymes including trypsin and chymotrypsin, and optionally amylase and lipase. In another particular embodiment, said proteolytic digestion is by trypsin and/or chymotrypsin. By “trypsin” is meant herein an enzyme of the EC 3.4.21.4 category, which is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins. Typically, trypsin cleaves peptides on the C-terminal side of lysine and arginine amino acid residues, but If a proline residue is on the carboxyl side of the cleavage site, the cleavage may not not occur, and if an acidic residue is on either side of the cleavage site, the rate of hydrolysis may be be slower. By “chymotrypsin” is meant herein an enzyme of the EC 3.4.21.1 category, which is a serine protease from the PA clan superfamily, found in the digestive system of vertebrates, where it hydrolyzes proteins. Typically, chymotrypsin cleaves peptide bonds involving L-isomers of tyrosine, phenylalanine, and tryptophan. 
     By “resistant to proteolytic digestion” is meant herein that the chimeric RBP is not cleaved by said proteases and/or remains stable when contacted with said proteases and/or keeps its activity when contacted with said proteases. Techniques to determine if a protein is resistant to proteolytic digestion by pancreatin, in particular by trypsin and/or chymotrypsin, typically include exposing said protein to simulated intestinal fluid (SIF) in the presence or absence of pancreatin, typically at 2% w/v, for example at pH 6.8, typically for 3 h, in particular at 37° C., then determining the activity of said treated protein (for example by titration of the bacterial delivery vehicle comprising said chimeric RBP in bacteria which are specifically targeted by packaged phagemid comprising said RBPs) and comparing it with the activity of same but non-treated protein. In the context of the present disclosure, a chimeric RBP is preferably considered as resistant to proteolytic digestion if the titer of the bacterial delivery vehicle comprising said chimeric RBP in bacteria which are specifically targeted by said RBPs decreases of 1 log or less, after treatment with pancreatin, typically at 2% w/v, for example at pH 6.8, typically for 3 h, in particular at 37° C. compared to the titer of the same but non-treated bacterial delivery vehicle comprising the same chimeric RBP targeting the same bacteria. 
     Chimeric RBP 
     As used herein, a receptor binding protein or RBP is a polypeptide that recognizes, and optionally binds and/or modifies or degrades a substrate located on the bacterial outer envelope, such as, without limitation, bacterial outer membrane, LPS, capsule, protein receptor, channel, structure such as the flagellum, pili, secretion system. The substrate can be, without limitation, any carbohydrate or modified carbohydrate, any lipid or modified lipid, any protein or modified protein, any amino acid sequence, and any combination thereof. 
     Such bacteriophage RBPs, from which the RBP portions are derived, include, for example, “L-shape fibers”, “side tail fibers (stfs)”, “long tail fibers” or “tailspikes.” In a preferred embodiment, the RBPs have a host range that is directed to specific bacterial cells of the host or subject microbiome. In one specific aspect, the different RBP of the chimeric RBPis derived from any bacteriophage or from any bacteriocin. 
     In an embodiment, said chimeric RBP is a chimeric side tail fiber (STF) protein. 
     In a particular embodiment, the chimeric STF comprises an N-terminal region of an STF derived from a lambdoid bacteriophage, preferably a lambda or lambda-like bacteriophage, fused through said designed linker region, to a C-terminal region of a STF protein derived from a different bacteriophage. Such chimeric RBPs include those having an altered host range and/or biological activity such as, for example, depolymerase activity. 
     As used herein, lambdoid bacteriophages comprise a group of related viruses that infect bacteria. The viruses are termed lambdoid because one of the first members to be described was lambda (λ). Lambdoid bacteriophages are members of the Caudovirus order (also known as tailed bacteriophages) and include those bacteriophages with similar lifestyles, including, for example, the ability to recombine when intercrossed, possession of identical pairs of cohesive ends, and prophages that are inducible by ultraviolet irradiation. Although members of the order may have genomes that vary at the nucleotide level, they carry regions of sufficient nucleotide sequence identity to guide recombination between themselves, typically giving rise to a fully functional phage that has all the necessary genes. (See, for example, Casjens and Hendrix (2015) Virology 479-480:310-330). For purposes of the present disclosure, lambdoid bacteriophages for use as delivery vehicles, as well as lambdoid STF for use, would be understood generally by one skilled in the art. 
     Lambdoid phages can be defined as belonging to the lambda supercluster based on genomic analysis [9]. Within this supercluster, several clusters can be distinguished, each having a prototypical phage. The phage-like clusters and their members (between brackets) are: Lambda-like (lambda (λ), HK630, HK629), phi80-like (phi80, HK225, mEp237), N15-like (N15, PY54, phiKO2), HK97-like (HK97, HK022, HK75, HK106, HK140, HK446, HK542, HK544, HK633, mEpX1, mEpX2, mEp234, mEp235, mEp390, ENT39118), ES18-like (ES18, Oslo, SPN3UB), Gifsy-2-like (gifsy-2, gifsy-1, Fels-1, mEp043, mEp213, CP-1639, CTD-Iø, mEp640, FSL_SP-016), BP-4795-like (BP-4795, 2851, stx2-1717, YYZ-2008), SfV-like (SfV, SfII, SflV, SfI, øP27, ST64B), P22-like (P22, L, SPN9CC, ST64T, ST104, ST160, epsilon34, g341, SE1, Emek, φ20, IME10, Sf6, HK620, CUS-3, SPC-P1), APSE-1-like (APSE-1, APSE-2), 933W-like (933W, stx1ø, stx2ø-I, stx2ø-II, stx2-86, min27, ø24B, P13374, TL-2011c, VT2-sakai, VT2ø_272), HK639-like (HK639), øES15-like (øES15), HS2-like (HS2), ENT47970-like (ENT47670), ZF40-like (ZF40), øEt88-like (øEt88). Lambdoid phages further encompass any bacteriophage encoding a RBP having amino acids sequence homology of around 35% identity for 45 amino acids or more, around 50% identify for 30 amino acids or more, or around 90% identity for 18 amino acids or more in one or more of three amino acids regions ranging from positions 1-150, 320-460, and 495-560 with reference to the lambda bacteriophage STF sequence SEQ ID NO: 8, independently of other amino acids sequences encoded by said bacteriophage. 
     In the present disclosure a lambdoid STF protein includes, for example, a protein comprising or consisting of an amino acid sequence with at least 75% identity up to an amino acid corresponding to amino acid 130 of lambda STF (Uniprot P03764 SEQ ID NO: 8), in particular up to amino acid 130 of said lambda STF. 
     In one aspect, the STF protein includes a protein that comprises or consists of an amino acid sequence with 80, 85, 90, 95, 96, 97, 98, or 99% sequence identity with the wild type lambda STF protein amino acid sequence of SEQ ID NO: 8, or with any of the chimeric STF proteins disclosed herein. 
     As used herein, the percent homology between two sequences is equivalent to the percent identity between the two sequences. The percent identity is calculated in relation to polymers (e.g., polynucleotide or polypeptide) whose sequences have been aligned. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % homology = # of identical positions / total # of positions × 100), taking into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm, as described in the non-limiting examples below. 
     The percent identity between two amino acid sequences can be determined using the algorithm of E. Meyers and W. Miller (Comput. Appl. Biosci., 4: 11-17 (1988)) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. In addition, the percent identity between two amino acid sequences can be determined using the Needleman and Wunsch (J. Mol. Biol. 48:444-453 (1970)) algorithm which has been incorporated into the GAP program in the GCG software package (available at www.gcg.com), using a BLOSUM62 matrix, a BLOSUM30 matrix or a PAM250 matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2, 3, 4, 5, or 6. In a specific embodiment the BLOSUM30 matrix is used with gap open penalty of 12 and gap extension penalty of 4.

Indeed, as explained above, it is shown that, even if these “wild-type” RBPs are resistant to proteolytic digestion, using isolated regions from these stable RBPs to produce chimeras may lead to the production of a chimera which is not resistant to proteolytic digestion.

In certain aspects, the homology is around 35% identity for 45 amino acids or more, around 50% identify for 30 amino acids or more, or around 90% identity for 18 amino acids or more within the one or more of three amino acids regions ranging from positions 80-150, 320-460, and 495-560 of the STF protein with reference to the lambda bacteriophage STF sequence. In one specific aspect, the C-terminal region of the chimeric STF protein is derived from a bacteriophage or a bacteriocin. In one aspect, the chimeric STF protein comprises an N-terminal region of a STF protein fused to a C-terminal region of a STF protein derived from a different bacteriophage within one of the amino acids regions selected from positions 80-150, 320-460, or 495-560 of the N-terminal STF region with reference to the lambda bacteriophage STF sequence (SEQ ID NO: 8).

The engineered chimeric branched-RBP typically comprises two or more associated RBPs, derived from bacteriophages, which associate with one another based on the presence of interaction domains (IDs). The association of one subunit with another can be non-covalent or covalent. Each of the polypeptide subunits contain IDs that function as “anchors” for association of one subunit RBP with another. In specific embodiments, the chimeric branched-RBP may comprise multiple RBP subunits, including, for example, two, three, four, etc. subunits. 
     The individual RBP subunit may bring different biological functions to the overall engineered chimeric branched-RBP.

     The bacterial delivery vehicles provided herein enable transfer of a nucleic acid payload, encoding a protein or nucleic acid of interest, into a desired target bacterial host cell. 
     Delivery Vehicle 
     As used herein, the term “delivery vehicle” refers to any means that allows the transfer of a payload into a bacterium. There are several types of delivery vehicles encompassed by the present disclosure including, without limitation, bacteriophage scaffold, virus scaffold, chemical based delivery vehicle (e.g., cyclodextrin, calcium phosphate, cationic polymers, cationic liposomes), protein-based or peptide-based delivery vehicle, lipid-based delivery vehicle, nanoparticle-based delivery vehicles, non-chemical-based delivery vehicles (e.g., transformation, electroporation, sonoporation, optical transfection), particle-based delivery vehicles (e.g., gene gun, magnetofection, impalefection, particle bombardment, cell-penetrating peptides) or donor bacteria (conjugation). Any combination of delivery vehicles is also encompassed by the present disclosure. The delivery vehicle can refer to a bacteriophage derived scaffold and can be obtained from a natural, evolved or engineered capsid. 
     The bacterial delivery vehicles provided herein which enable transfer of a nucleic acid payload, encoding a protein or nucleic acid of interest, into a desired target bacterial host cell are characterized by having a chimeric RBP resistant to proteolytic digestion, in particular within the gastrointestinal tract, as defined in the section “Chimeric RBP” above. 
     In a particular embodiment, said chimeric RBP is a chimeric STF protein as defined in the section “Chimeric RBP” above. In a particular embodiment, said chimeric STF protein is a functional STF protein. 
     As used herein, a functional protein means in general a protein with a biological activity; more specifically a functional chimeric protein relates to a chimeric protein contributing to the efficient delivery of a DNA payload into a target strain. The efficiency threshold depends on a number of factors such as the type of protein, type of target strain and type of environment. For instance, STF and gpJ proteins allow for recognition, binding (and in some cases also degradation) of an extracellular epitope such as LPS, capsules and outer membrane proteins; gpH proteins allow for an efficient injection and hence successful passage of the DNA payload through the periplasm. 
     In some embodiments, the bacterial delivery vehicles disclosed herein further comprise the corresponding natural chaperone proteins (designated “accessory proteins” or “AP”) of the chimeric RBPs. Such AP proteins assist in the folding of the chimeric RBPs. 
     In a particular embodiment, the chimeric STF protein has enzyme activity such as depolymerase activity and the bacterial cell population of interest comprises encapsulated bacteria. 
     Bacterial delivery vehicles are also provided that further comprise recombinant gpJ proteins. Such gpJ proteins include recombinant gpJ proteins, including chimeric proteins as defined in the section “Chimeric RBP” above, that permit recognition of a bacterial cell receptor other than the LamB OMP receptor.

By “C-terminal region” of a gpJ protein from a bacteriophage is meant herein an amino acid region of said gpJ protein starting at positions 810-825 or 950-970 of said gpJ protein, said positions being with reference to the lambda bacteriophage gpJ protein sequence (SEQ ID NO: 22), and ending at the C-terminal end of said gpJ protein. 
     For production of chimeric gpJ proteins, two insertion points, located respectively at positions corresponding to amino acids 814-821 and 958-966 of the lambda bacteriophage gpJ protein sequence (SEQ ID NO: 22) have previously been identified by the inventors. In non-limiting aspects, such insertion sites may be utilized for production of chimeric proteins. Both insertion points yield functional gpJ chimeras with altered receptor binding.

In said embodiment, the chimeric gpJ variant may be H591 comprising or consisting of the amino acid sequence SEQ ID NO: 23 and typically encoded by the nucleotide sequence SEQ ID NO: 24, said H591 chimeric gpJ variant typically recognizing and binding OmpC. In another embodiment, the chimeric gpJ protein comprises a fusion between the N-terminal region of a lambda bacteriophage gpJ protein and the C-terminal region of a gpJ protein from a different bacteriophage, which typically recognizes a receptor present in O157 strains, said N-terminal region being in particular fused to said C-terminal region within the amino acid region 810-825 of the N-terminal region with reference to the lambda bacteriophage gpJ protein sequence (SEQ ID NO: 22).

One such variant is the “gpH-IAI” variant of amino acid sequence SEQ ID NO: 31. 
     In a particular embodiment, said bacterial delivery vehicle comprises chimeric STF of sequence SEQ ID NO: 11 and chimeric gpJ variant of sequence SEQ ID NO: 27. 
     In a particular embodiment, the lambdoid delivery vehicle as disclosed above further comprises a functional lambdoid bacteriophage gpJ protein, as defined above, and/or a functional lambdoid bacteriophage gpH protein, as defined above. 
     In aspects, the bacterial delivery vehicles provided herein, are vehicles wherein the one or more of the chimeric STF protein, the gpJ protein and/or the gpH protein are further engineered to increase the efficiency of transfer of the DNA payload into the targeted bacterial cell population. Such bacterial cell populations include for example E.  coli . and other bacterial species of interest. 
     In a particular embodiment, the delivery vehicle is incapable of self-reproduction. 
     In the context of the present invention, “self-reproduction” is different from “self-replication”, “self-replication” referring to the capability of replicating a nucleic acid, whereas “self-reproduction” refers to the capability of having a progeny, in particular of producing new delivery vehicles, said delivery vehicles being either produced empty or with a nucleic acid of interest packaged. 
     By “delivery vehicle incapable of self-reproduction” is meant herein that at least one, several or all functional gene(s) necessary to produce said delivery vehicle is(are) absent from said delivery vehicle (and from said vector included in said delivery vehicle). In a preferred embodiment, said at least one, several or all functional gene(s) necessary to produce said delivery vehicle is(are) present in the donor cell as defined above, preferably in a plasmid, in the chromosome or in a helper phage present in the donor cell as defined below, enabling the production of said delivery vehicle in said donor cell. 
     In the context of the invention, said functional gene(s) necessary to produce said delivery vehicle may be absent through (i) the absence of the corresponding gene or (ii) the presence of the corresponding gene but in a non-functional form. 
     In an embodiment, the sequence of said gene necessary to produce said delivery vehicle is absent from said delivery vehicle. In a preferred embodiment, the sequence of said gene necessary to produce said delivery vehicle has been replaced by a nucleic acid sequence of interest. 
     Alternatively, said gene necessary to produce said delivery vehicle is present in said delivery vehicle in a non-functional form, for example in a mutant non-functional form, or in a non-expressible form, for example with deleted or mutated non-functional regulators. In a preferred embodiment, said gene necessary to produce said delivery vehicle is present in said delivery vehicle in a mutated form which renders it non-functional in the target cell, while remaining functional in the donor cell. 
     In the context of the invention, genes necessary to produce said delivery vehicle encompass any coding or non-coding nucleic acid required for the production of said delivery vehicle. 
     Examples of genes necessary to produce said delivery vehicle include genes encoding phage structural proteins; phage genes involved in the control of genetic expression; phage genes involved in transcription and/or translation regulation; phage genes involved in phage DNA replication; phage genes involved in production of phage proteins; phage genes involved in phage proteins folding; phage genes involved in phage DNA packaging; and phage genes encoding proteins involved in bacterial cell lysis. 
     Packaged Phagemids 
     Delivery vehicles include packaged phagemids, as well as bacteriophage, as disclosed herein. An eligobiotic® is a packaged phagemid, i.e a payload encapsidated in a phage-derived capsid. The engineering of such delivery vehicles is well known to those skilled in the art. Such engineering techniques may employ production cell lines engineered to express the STF, gpJ and gpH proteins disclosed herein. The present disclosure thus also provides a production cell line expressing the chimeric RBPs provided herein. 
     In one aspect, bacterial delivery vehicles with desired target host ranges are provided for use in transfer of a payload to the microbiome of a host. The bacterial delivery vehicles may be characterized by combinations of chimeric STF, and wild-type and engineered gpJ and gpH proteins. 
     Generation of packaged phagemids and bacteriophage particles are routine techniques well-known to one skilled in the art. In an embodiment, a satellite phage and/or helper phage may be used to promote the packaging of the payload in the delivery vehicles disclosed herein. Helper phages provide functions in trans and are well known to the man skilled in the art. The helper phage comprises all the genes coding for the structural and functional proteins that are indispensable for the payload to be packaged, (i.e. the helper phage provides all the necessary gene products for the assembly of the delivery vehicle). The helper phage may contain a defective origin of replication or packaging signal, or completely lack the latter, and hence it is incapable of self-packaging, thus only bacterial delivery particles carrying the payload or plasmid will be produced. Helper phages may be chosen so that they cannot induce lysis of the host used for the delivery particle production. One skilled in the art would understand that some bacteriophages are defective and need a helper phage for payload packaging. Thus, depending on the bacteriophage chosen to prepare the bacterial delivery particles, the person skilled in the art would know if a helper phage is required. Sequences coding for one or more proteins or regulatory processes necessary for the assembly or production of packaged payloads may be supplied in trans. For example, the STF, gpJ and gpH proteins of the present disclosure may be provided in a plasmid under the control of an inducible promoter or expressed constitutively. In this case, the phage wild-type sequence may or not contain a deletion of the gene or sequence supplied in trans. Additionally, chimeric or modified phage sequences encoding a new function, like an engineered STF, gpJ or gpH protein, may be directly inserted into the desired position in the genome of the helper phage, hence bypassing the necessity of providing the modified sequence in trans. Methods for both supplying a sequence or protein in trans in the form of a plasmid, as well as methods to generate direct genomic insertions, modifications and mutations are well known to those skilled in the art. 
     In a particular embodiment, said helper phage comprises a nucleic acid sequence encoding the chimeric RBP comprising or consisting of the sequence SEQ ID NO: 11, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 19, and said helper phage optionally further comprises a nucleic acid sequence encoding the chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 27, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 28. 
     In a particular embodiment, said helper phage is a lambda prophage wherein (i) the nucleic acid encoding a wild-type STF protein has been replaced by a nucleic acid sequence encoding the chimeric RBP comprising or consisting of the sequence SEQ ID NO: 11, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 19, (ii) the nucleic acid encoding a wild-type gpJ protein has been replaced by a nucleic acid sequence encoding the chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 27, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 28, and (iii) the Cos site has been removed, and wherein optionally (iv) the helper prophage contains a mutation which prevents spontaneous cell lysis, such as the Sam7 mutation and (v) the helper prophage contains a thermosensitive version of the master cI repressor, such as the cI857 version. 
     Another object of the disclosure thus also concerns providing a production cell line, as defined above, comprising a helper phage as defined above. 
     In a particular embodiment, said bacterial delivery vehicle comprises said DNA payload of interest. 
     Payload 
     As used herein, the term “payload” refers to any nucleic acid sequence or amino acid sequence, or a combination of both (such as, without limitation, peptide nucleic acid or peptide-oligonucleotide conjugate) transferred into a bacterium with a delivery vehicle. The term “payload” may also refer to a plasmid, a vector or a cargo. The payload can be a phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome. The payload can also be composed only in part of phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome. 
     In a particular embodiment, the payload has a size superior or equal to 4 kbp, and preferably inferior or equal to 51 kb. 
     In said embodiment, the payload may have a size, an integer multiple of which is between 36 kb and 51 kb. In other words, in that embodiment, there is at least an integer n, such as 36 kb ≤ n × size of the payload ≤ 51 kb . 
     As described herein it is more particularly demonstrated that it is possible to produce a more uniform population of bacterial delivery vehicles comprising an almost unique number of payload copies when said payload has a size of a specific range. 
     In a particular embodiment, the payload has a size strictly superior to 10.000 kb and strictly inferior to 12.000 kb. In an alternative embodiment, the payload has a size strictly superior to 12.500 kb and strictly inferior to 16.667 kb, in particular a size strictly superior to 12.500 kb and inferior to 13.000 kb. 
     In another particular embodiment, the payload has a size superior or equal to 18.000 kb and inferior or equal to 25.000 kb, in particular inferior or equal to 24.000 kb. 
     In a particular embodiment, said payload has a size of 11.6 kb. 
     The payload may be a nucleic acid plasmid that is able to circularize upon transfer into the target cell and then either replicate or integrate inside the chromosome. Replication of the vector DNA is dependent on the presence of a bacterial origin of replication. Once replicated, inheritance of the plasmid into each of the daughter cells can be mediated by the presence of an active partitioning mechanism and a plasmid addiction system such as toxin/anti-toxin system. 
     As used herein, the term “nucleic acid” refers to a sequence of at least two nucleotides covalently linked together which can be single-stranded or double-stranded or contains portion(s) of both single-stranded and double-stranded sequence. Nucleic acids can be naturally occurring, recombinant or synthetic. The nucleic acid can be in the form of a circular sequence or a linear sequence or a combination of both forms. The nucleic acid can be DNA, both genomic or cDNA, or RNA or a combination of both. The nucleic acid may contain any combination of deoxyribonucleotides and ribonucleotides, and any combination of bases, including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine, hypoxanthine, isocytosine, 5-hydroxymethylcytosine and isoguanine. Other examples of modified bases that can be used are detailed in Chemical Reviews 2016, 116 (20) 12655-12687. The term “nucleic acid” also encompasses any nucleic acid analogs which may contain other backbones comprising, without limitation, phosphoramide, phosphorothioate, phosphorodithioate, O-methylphosphoroamidite linkage and/or deoxyribonucleotides and ribonucleotides nucleic acids. Any combination of the above features of a nucleic acid is also encompassed by the present disclosure. 
     Origins of replication known in the art have been identified from species-specific plasmid DNAs (e.g. ColE1, R1, pT181, pSC101, pMB1, R6K, RK2, p15a and the like), from bacterial virus (e.g. φX174, M13, F1 and P4) and from bacterial chromosomal origins of replication (e.g. oriC). In one embodiment, the phagemid according to the disclosure comprises a bacterial origin of replication that is functional in the targeted bacteria. 
     Alternatively, the plasmid according to the disclosure does not comprise any functional bacterial origin of replication or contain an origin of replication that is inactive in the targeted bacteria. Thus, the plasmid of the disclosure cannot replicate by itself once it has been introduced into a bacterium by the bacterial virus particle. 
     In one embodiment, the origin of replication on the plasmid to be packaged is inactive in the targeted bacteria, meaning that this origin of replication is not functional in the bacteria targeted by the bacterial virus particles, thus preventing unwanted plasmid replication. 
     In one embodiment, the plasmid comprises a bacterial origin of replication that is functional in the bacteria used for the production of the bacterial virus particles. 
     Plasmid replication depends on host enzymes and on plasmid-controlled cis and trans determinants. For example, some plasmids have determinants that are recognized in almost all gram-negative bacteria and act correctly in each host during replication initiation and regulation. Other plasmids possess this ability only in some bacteria (Kues, U and Stahl, U 1989 Microbiol Rev 53:491-516). 
     Plasmids are replicated by three general mechanisms, namely theta type, strand displacement, and rolling circle (reviewed by Del Solar et al. 1998 Microhio and Molec Biol. Rev 62:434-464) that start at the origin of replication. These replication origins contain sites that are required for interactions of plasmid and/or host encoded proteins. 
     Origins of replication used on the plasmid of the disclosure may be of moderate copy number, such as colEl ori from pBR322 (15-20 copies per cell) or the R6K plasmid (15-20 copies per cell) or may be high copy number, e.g. pUC oris (500-700 copies per cell), pGEM oris (300-400 copies per cell), pTZ oris (&gt;1000 copies per cell) or pBluescript oris (300-500 copies per cell). 
     In one embodiment, the bacterial origin of replication is selected in the group consisting of ColE1, pMB1 and variants (pBR322, pET, pUC, etc), p15a, ColA, ColE2, pOSAK, pSC101, R6K, IncW (pSa etc), IncFII, pT181, P1, F IncP, IncC, IncJ, IncN, IncP1, IncP4, IncQ, IncH11, RSF1010, CloDF13, NTP16, R1, f5, pPS10, pC194, pE194, BBR1, pBC1, pEP2, pWVO1, pLF1311, pAP1, pWKS1, pLS1, pLS11, pUB6060, pJD4, pIJ101, pSN22, pAMbeta1, pIP501, pIP407, ZM6100(Sa), pCU1, RA3, pMOL98, RK2/RP4/RP1/R68, pB10, R300B, pRO1614, pRO1600, pECB2, pCM1, pFA3, RepFIA, RepFIB, RepFIC, pYVE439-80, R387, phasyl, RA1, TF-FC2, pMV158 and pUB113. 
     In an embodiment, the bacterial origin of replication is a E.coli origin of replication selected in the group consisting of ColE1, pMB1 and variants (pBR322, pET, pUC, etc), p15a, ColA, ColE2, pOSAK, pSC101, R6K, IncW (pSaetc), IncFII, pT181, P1, F IncP, IncC, IncJ, IncN, IncP1, IncP4, IncQ, IncH11, RSF1010, CloDF13, NTP16, R1, f5 and pPS10. 
     In an embodiment, the bacterial origin of replication is selected in the group consisting of pC194, pE194, BBR1, pBC1, pEP2, pWVO1, pLF1311, pAP1, pWKS1, pLS1, pLS11, pUB6060, pJD4, pIJ101, pSN22, pAMbeta1, pIP501, pIP407, ZM6100(Sa), pCU1, RA3, pMOL98, RK2/RP4/RP1/R68, pB10, R300B, pRO1614, pRO1600, pECB2, pCM1, pFA3, RepFIA, RepFIB, RepFIC, pYVE439-80, R387, phasyl, RA1, TF-FC2, pMV158 and pUB113. 
     In an embodiment, the bacterial origin of replication is ColE1. 
     The delivered nucleic acid sequence according to the disclosure may comprise a phage replication origin which can initiate, with complementation of a complete phage genome, the replication of the delivered nucleic acid sequence for later encapsulation into the different capsids. 
     A phage origin of replication comprised in the delivered nucleic acid sequence of the disclosure can be any origin of replication found in a phage. 
     In an embodiment, the phage origin of replication can be the wild-type or non-wildtype sequence of the M13, fl, φX174, P4, lambda, P2, lambda-like, HK022, mEP237, HK97, HK629, HK630, mEP043, mEP213, mEP234, mEP390, mEP460, mEPx1, mEPx2, phi80, mEP234, T2, T4, T5, T7, RB49, phiX174, R17, PRD1 Pl-like, P2-like, P22, P22-like, N15 and N15-like bacteriophages. 
     In an embodiment, the phage origin of replication is selected in the group consisting of phage origins of replication of M13, fl, φX174, P4, and lambda. 
     In a particular embodiment, the phage origin of replication is the lambda or P4 origin of replication. In a particular embodiment, the phage origin of replication is from Propionibacterium phages: BW-like phages such as Doucette, B22, E6, G4, BV-like phages such as Anatole, E1, B3, BX-like phages such as PFR1 and PFR2, filamentous B5 phage, BU-like phages ( Cutibacterium acnes  phages). 
     In a particular embodiment, the payload or vector comprises a conditional origin of replication which is inactive in the targeted bacteria but is active in a donor bacterial cell. 
     In the context of the invention, a “conditional origin of replication” refers to an origin of replication whose functionality may be controlled by the presence of a specific molecule. 
     In a particular embodiment, the conditional origin of replication is an origin of replication, the replication of which depends upon the presence of one or more given protein, peptid, RNA, nucleic acid, molecule or any combination thereof. 
     In a particular embodiment, the replication of said origin of replication may further depend on a process, such as transcription, to activate said replication. 
     In the context of the invention, said conditional origin of replication is inactive in the targeted bacteria because of the absence of said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof in said targeted bacteria. 
     In a particular embodiment, said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof. In a particular embodiment, said protein, peptid, RNA nucleic acid, molecule or any combination thereof is expressed in trans in said donor bacterial cell. 
     By “in trans” is meant herein that said protein, peptid, RNA, nucleic acid, molecule or any combination thereof is not encoded on the same nucleic acid molecule as the one comprising the origin of replication. In a particular embodiment, said protein, peptid, RNA, nucleic acid, molecule or any combination thereof is encoded on a chromosome or on a vector, in particular a plasmid. In a particular embodiment, said vector comprises an antibiotic resistance marker. In an alternative embodiment, said vector is devoid of antibiotic resistance marker. 
     Since said conditional origin of replication is inactive in the targeted bacteria because of the absence of said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof in said targeted bacteria, said conditional origin of replication may be selected depending on the specific bacteria to be targeted. 
     The conditional origin of replication disclosed herein may originate from plasmids, bacteriophages or PICIs which preferably share the following characteristics: they contain in their origin of replication repeat sequences, or iterons, and they code for at least one protein interacting with said origin of replication (i.e. Rep, protein O, protein P, pri) which is specific to them. 
     By way of example, mention may be made of the conditional replication systems of the following plasmids and bacteriophages: RK2, R1, pSC101, F, Rts1, RSF1010, P1, P4, lambda, phi82, phi80. 
     In a particular embodiment, said conditional origin of replication is selected from the group consisting of the R6Kλ, DNA replication origin and derivatives thereof, the IncPα oriV origin of replication and derivatives thereof, ColE1 origins of replication modified to be under an inducible promoter, and origins of replication from phage-inducible chromosomal islands (PICIs) and derivatives thereof. 
     In a particular embodiment, said conditional origin of replication is an origin of replication present in less than 50%, or less than 40%, less than 30%, less than 20%, less than 10% or less than 5% of the bacteria of the host microbiome. 
     In another particular embodiment, said conditional origin of replication comprises or consists of a sequence less than 80% identical, in particular less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, less than 5% or less than 1% identical to the sequences of the origins of replication of the bacteria of the host microbiome, in particular of the bacteria representing more than 50%, more particularly more than 60%, more than 70%, more than 80%, more than 90% or more than 95% of the host microbiome. 
     As used herein, the term “phage-inducible chromosomal islands” or “PICIs” refers to mobile genetic elements having a conserved gene organization, and encode a pair of divergent regulatory genes, including a PICI master repressor. Typically, in Gram-positive bacteria, left of rpr, and transcribed in the same direction, PICIs encode a small set of genes including an integrase (int) gene; right of rpr, and transcribed in the opposite direction, the PICIs encode an excision function (xis), and a replication module consisting of a primase homolog (pri) and optionally a replication initiator (rep), which are sometimes fused, followed by a replication origin (ori), next to these genes, and also transcribed in the same direction, PICIs encode genes involved in phage interference, and optionally, a terminase small subunit homolog (terS). 
     In a particular embodiment, said conditional origin of replication is an origin of replication derived from phage-inducible chromosomal islands (PICIs). 
     A particular conditional origin of replication has indeed been derived from PICIs. 
     It was shown that it is possible to derive novel conditionally replicative vectors or payloads, in particular based on the primase-helicase and origin of replication from PICIs. These origins may be relatively rare in target strains, and more advantageously the primase-ori pair may be unique for each PICI, significantly reducing the possibility of undesired recombination or payload spread events. They can further be modified to further limit recombination chances and remove restriction sites to bypass target bacteria defense systems. 
     In a particular embodiment, said conditional origin of replication is derived from the origin of replication from the PICI of the Escherichia coli strain CFT073, disclosed in Fillol-Salom et al. (2018) The ISME Journal 12:2114-2128. 
     In a particular embodiment, said conditional origin of replication is the primase ori from the PICI of the  Escherichia coli  strain CFT073, typically of sequence SEQ ID NO: 46. 
     In another particular embodiment, said conditional origin of replication is the primase ori from the PICI of the  Escherichia coli  strain CFT073, devoid of at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15 or at least 16 restriction site(s) selected from the group consisting of GAAABCC, GCCGGC, RCCGGY, GCNGC, TWCANNNNNNTGG (SEQ ID NO: 47), TGGCCA, ACCYAC, YGGCCR, AGACC, GCWGC, GGGANGC, GKAGATD, GCCGGYYD, GGCYAC, RGCCGGYYD, and VGCCGGYBD. 
     In a particular embodiment, said conditional origin of replication is the primase ori from the PICI of the  Escherichia coli  strain CFT073, devoid of the restriction site GAAABCC. 
     Preferably, said conditional origin of replication is of sequence SEQ ID NO: 48. 
     In another particular embodiment, said conditional origin of replication is the primase ori from the PICI of the Escherichia coli strain CFT073 devoid of the restriction sites GAAABCC, GCCGGC, RCCGGY, GCNGC, TWCANNNNNNTGG (SEQ ID NO: 47), TGGCCA, ACCYAC, YGGCCR, AGACC, GCWGC, GGGANGC, GKAGATD, GCCGGYYD, GGCYAC, RGCCGGYYD, and VGCCGGYBD. Preferably, said conditional origin of replication is of sequence SEQ ID NO: 49. 
     In a particular embodiment, wherein said origin of replication is derived from phage-inducible chromosomal islands (PICIs), said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses a rep protein, in particular a primase-helicase, in particular a primase-helicase of sequence SEQ ID NO: 50, typically encoded by a nucleic acid comprising or consisting of the sequence SEQ ID NO: 51. 
     It was demonstrated that these specific conditional origins of replication were particularly compatible with lambda-based packaging, leading to sufficiently high titers (&gt;10 10  /mL) required for microbiota-related applications. 
     In a particular embodiment, when said payload or vector is a phagemid, said origin of replication may be derived from a microorganism which is different from the one that is used to encode the structural elements of the capsid packaging said phagemid. 
     By “donor bacterial cell” is meant herein a bacterium that is capable of hosting a payload or vector as defined above, of producing a payload or vector as defined above and/or which is capable of transferring said payload or vector as defined above to another bacterium. In a particular embodiment, said payload or vector may be a phagemid, and said donor bacterial cell may then be a bacterial cell able to produce said phagemid, more particularly in the form of a packaged phagemid. 
     Preferably, said donor bacterial cell stably comprises said payload or vector and is able to replicate said payload or vector. 
     In a particular embodiment, when the conditional origin of replication of said payload or vector is an origin of replication, the replication of which depends upon the presence of a given protein, peptid, nucleic acid, RNA, molecule or any combination thereof, said donor bacterial cell expresses said protein, peptid, nucleic acid, RNA, molecule or any combination thereof. 
     Preferably, said protein, peptid, nucleic acid, RNA, molecule or any combination thereof is expressed in trans, as defined above. 
     In a particular embodiment, said donor bacterial cell stably comprises a nucleic acid encoding said protein, peptid, nucleic acid, RNA, molecule or any combination thereof. 
     In a particular embodiment, when said origin of replication is derived from phage-inducible chromosomal islands (PICIs), said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses a rep protein, in particular a primase-helicase, in particular a primase-helicase of sequence SEQ ID NO: 50. 
     In a particular embodiment, said donor bacterial cell stably comprises a nucleic acid encoding said rep protein, in particular said primase-helicase, said nucleic acid typically comprising or consisting of the sequence SEQ ID NO: 51. 
     In a particular embodiment, said donor bacterial cell is a production cell line, in particular a cell line producing packaged phagemids including the payload or vector of the invention. 
     The delivered nucleic acid of interest preferably comprises a nucleic acid sequence under the control of a promoter. In certain embodiments, the nucleic acid of interest is selected from the group consisting of a Cas nuclease gene, a Cas9 nuclease gene, a guide RNA, a CRISPR locus, a toxin gene, a gene expressing an enzyme such as a nuclease or a kinase, a TALEN, a ZFN, a meganuclease, a recombinase, a bacterial receptor, a membrane protein, a structural protein, a secreted protein, a gene expressing resistance to an antibiotic or to a drug in general, a gene expressing a toxic protein or a toxic factor, and a gene expressing a virulence protein or a virulence factor, and any of their combination. In an embodiment, the nucleic acid payload encodes a therapeutic protein. In another embodiment, the nucleic acid payload encodes an antisense nucleic acid molecule. 
     In one embodiment, the sequence of interest is a programmable nuclease circuit to be delivered to the targeted bacteria. This programmable nuclease circuit is able to mediate in vivo sequence-specific elimination of bacteria that contain a target gene of interest (e.g. a gene that is harmful to humans). Some embodiments of the present disclosure relate to engineered variants of the Type II CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-associated) system of Streptococcus pyogenes. Other programmable nucleases that can be used include other CRISPR-Cas systems, engineered TALEN (Transcription Activator-Like Effector Nuclease) variants, engineered zinc finger nuclease (ZFN) variants, natural, evolved or engineered meganuclease or recombinase variants, and any combination or hybrids of programmable nucleases. Thus, the engineered autonomously distributed nuclease circuits provided herein may be used to selectively cleave DNA encoding a gene of interest such as, for example, a toxin gene, a virulence factor gene, an antibiotic resistance gene, a remodeling gene or a modulatory gene (cf. WO2014124226). 
     Other sequences of interest, such as programmable sequences, can be added to the delivered nucleic acid sequence so as to be delivered to targeted bacteria. In an embodiment, the sequence of interest added to the delivered nucleic acid sequence leads to cell death of the targeted bacteria. For example, the nucleic acid sequence of interest added to the plasmid may encode holins or toxins. 
     Alternatively, the sequence of interest circuit added to the delivered nucleic acid sequence does not lead to bacteria death. For example, the sequence of interest may encode reporter genes leading to a luminescence or fluorescence signal. Alternatively, the sequence of interest may comprise proteins and enzymes achieving a useful function such as modifying the metabolism of the bacteria or the composition of its environment. 
     In a particular embodiment, the nucleic acid of interest is selected from the group consisting of Cas9, a single guide RNA (sgRNA), a CRISPR locus, a gene expressing an enzyme such as a nuclease or a kinase, a TALEN, a ZFN, a meganuclease, a recombinase, a bacterial receptor, a membrane protein, a structural protein, a secreted protein, resistance to an antibiotic or to a drug in general, a gene expressing a toxic protein or a toxic factor and a gene expressing a virulence protein or a virulence factor and any of their combination. 
     In a particular embodiment, the nucleic acid of interest is a gene expressing a nuclease. More particularly, the nuclease may target cleavage of a host bacterial cell chromosome or a host bacterial cell plasmid. In a more particular embodiment, the cleavage may occur in an antibiotic resistant gene. 
     In a particular embodiment, the delivered nucleic acid sequence according to the disclosure comprises a nucleic acid sequence of interest that encodes a bacteriocin, which can be a proteinaceous toxin produced by bacteria to kill or inhibit growth of other bacteria. Bacteriocins are categorized in several ways, including producing strain, common resistance mechanisms, and mechanism of killing. Such bacteriocin had been described from gram negative bacteria (e.g. microcins, colicin-like bacteriocins and tailocins) and from gram positive bacteria (e.g. Class I, Class II, Class III or Class IV bacteriocins). 
     In one embodiment, the delivered nucleic acid sequence according to the disclosure further comprises a sequence of interest encoding a toxin selected in the group consisting of microcins, colicin-like bacteriocins, tailocins, Class I, Class II, Class III and Class IV bacteriocins. 
     In a particular embodiment, the corresponding immunity polypeptide (i. e. anti-toxin) may be used to protect bacterial cells (see review by Cotter et al., Nature Reviews Microbiology 11: 95, 2013, which is hereby incorporated by reference in its entirety) for delivered nucleic acid sequence production and encapsidation purpose but is absent in the pharmaceutical composition and in the targeted bacteria in which the delivered nucleic acid sequence of the disclosure is delivered. 
     In one aspect of the disclosure, the CRISPR system is included in the delivered nucleic acid sequence. The CRISPR system contains two distinct elements, i.e. i) an endonuclease, in this case the CRISPR associated nuclease (Cas or “CRISPR associated protein”) and ii) a guide RNA. The guide RNA is in the form of a chimeric RNA which consists of the combination of a CRISPR (RNAcr) bacterial RNA and a RNAtracr (trans-activating RNA CRISPR) (Jinek et al., Science 2012). The guide RNA combines the targeting specificity of the RNAcr corresponding to the “spacing sequences” that serve as guides to the Cas proteins, and the conformational properties of the RNAtracr in a single transcript. When the guide RNA and the Cas protein are expressed simultaneously in the cell, the target genomic sequence can be permanently modified or interrupted. The modification is advantageously guided by a repair matrix. In general, the CRISPR system includes two main classes depending on the nuclease mechanism of action. Class 1 is made of multi-subunit effector complexes and includes type I, III and IV. Class 2 is made of single-unit effector modules, like Cas9 nuclease, and includes type II (II-A,II-B,II-C,II-C variant), V (V-A,V-B,V-C,V-D,V-E,V-U1,V-U2,V-U3,V-U4,V-U5) and VI (VI-A,VI-B1,VI-B2,VI-C,VI-D). 
     The sequence of interest according to the present disclosure comprises a nucleic acid sequence encoding Cas protein. A variety of CRISPR enzymes are available for use as a sequence of interest on the plasmid. In some embodiments, the CRISPR enzyme is a Type II CRISPR enzyme. In some embodiments, the CRISPR enzyme catalyzes DNA cleavage. In some other embodiments, the CRISPR enzyme catalyzes RNA cleavage. In one embodiment, the CRISPR enzymes may be coupled to a sgRNA. In certain embodiments, the sgRNA targets a gene selected in the group consisting of an antibiotic resistance gene, virulence protein or factor gene, toxin protein or factor gene, a bacterial receptor gene, a membrane protein gene, a structural protein gene, a secreted protein gene and a gene expressing resistance to a drug in general. 
     Non-limiting examples of Cas proteins as part of a multi-subunit effector or as a single-unit effector include Cas 1, Cas1B, Cas2, Cas3, Cas4, Cas5, Cas6, Cas7, Cas8, Cas9 (also known as Csn1 and Csx12), Cas10, Cas 11 (SS), Cas12a (Cpf1), Cas12b (C2c1), Cas12c (C2c3), Cas12d (CasY), Cas12e (CasX), C2c4, C2c8, C2c5, C2c10, C2c9, Cas13a (C2c2), Cas13b (C2c6), Cas13c (C2c7), Cas13d, Csa5, Csc1, Csc2, Cse1, Cse2, Csy1, Csy2, Csy3, Csf1, Csf2, Csf3, Csf4, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csn2, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx13, Csx1, Csx15, SdCpf1, CmtCpf1, TsCpf1, CmaCpf1, PcCpf1, ErCpf1, FbCpf1, UbcCpf1, AsCpf1, LbCpf1, Mad4, Mad7, Cms1, homologues thereof, orthologues thereof, variants thereof, or modified versions thereof. In some embodiments, the CRISPR enzyme cleaves both strands of the target nucleic acid at the Protospacer Adj acent Motif (PAM) site. In a particular embodiment, said Cas protein is Cas12a (Cpf1). 
     In a particular embodiment, the CRISPR enzyme is any Cas9 protein, for instance any naturally occurring bacterial Cas9 as well as any variants, homologs or orthologs thereof. 
     By “Cas9” is meant a protein Cas9 (also called Csn1 or Csx12) or a functional protein, peptide or polypeptide fragment thereof, i.e. capable of interacting with the guide RNA(s) and of exerting the enzymatic activity (nuclease) which allows it to perform the double-strand cleavage of the DNA of the target genome. “Cas9” can thus denote a modified protein, for example truncated to remove domains of the protein that are not essential for the predefined functions of the protein, in particular the domains that are not necessary for interaction with the gRNA(s).

     In one embodiment, the CRISPR system is used to target and inactivate a virulence factor. A virulence factor can be any substance produced by a pathogen that alters host-pathogen interaction by increasing the degree of damage done to the host. Virulence factors are used by pathogens in many ways, including, for example, in cell adhesion or colonization of a niche in the host, to evade the host’s immune response, to facilitate entry to and egress from host cells, to obtain nutrition from the host, or to inhibit other physiological processes in the host. Virulence factors can include enzymes, endotoxins, adhesion factors, motility factors, factors involved in complement evasion, and factors that promote biofilm formation. For example, such targeted virulence factor gene can be E. coli virulence factor gene such as, without limitation, EHEC-HlyA, Stx1 (VT1), Stx2 (VT2), Stx2a (VT2a), Stx2b (VT2b), Stx2c (VT2c), Stx2d (VT2d), Stx2e (VT2e) and Stx2f (VT2f), Stx2h (VT2h), fimA, fimF, fimH, neuC, kpsE, sfa, foc, iroN, aer, iha, papC, papGI, papGII, papGIII, hlyC, cnf1, hra, sat, ireA, usp ompT, ibeA, malX, fyuA, irp2, traT, afaD, ipaH, eltB, estA, bfpA, eaeA, espA, aaiC, aatA, TEM, CTX, SHV, csgA, csgB, csgC, csgD, csgE, csgF, csgG, csgH, T1SS, T2SS, T3SS, T4SS, T5SS, T6SS (secretion systems).

For example, such targeted virulence factor gene can be  Vibrio cholera  virulence factor gene such as, without limitation, ctxA and ctxB (cholera toxin), tcpA (toxin co-regulated pilus), and toxT (master virulence regulator). For example, such targeted virulence factor gene can be  Pseudomonas aeruginosa  virulence factor genes such as, without limitation, pyoverdine (e.g., sigma factor pvdS, biosynthetic genes pvdL, pvdl, pvdJ, pvdH, pvdA, pvdF, pvdQ, pvdN, pvdM, pvdO, pvdP, transporter genes pvdE, pvdR, pvdT, opmQ), siderophore pyochelin (e.g., pchD, pchC, pchB, pchA, pchE, pchF and pchG, and toxins (e.g., exoU, exoS and exoT). For example, such targeted virulence factor gene can be  Klebsiella pneumoniae  virulence factor genes such as, without limitation, fimA (adherence, type I fimbriae major subunit), and cps (capsular polysaccharide). For example, such targeted virulence factor gene can be  Acinetobacter baumannii  virulence factor genes such as, without limitation, ptk (capsule polymerization) and epsA (assembly). For example, such targeted virulence factor gene can be  Salmonella enterica  Typhi virulence factor genes such as, without limitation, MIA (invasion, SPI-1 regulator), ssrB (SPI-2 regulator), and those associated with bile tolerance, including efflux pump genes acrA, acrB and tolC.

     In another embodiment, the CRISPR/Cas system is used to target and inactivate a bacterial toxin gene. Bacterial toxins can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. The response to a bacterial toxin can involve severe inflammation and can lead to sepsis. Such toxin can be for example  Botulinum  neurotoxin,  Tetanus  toxin,  Staphylococus  toxins,  Diphteria  toxin,  Anthrax  toxin, Alpha toxin,  Pertussis  toxin,  Shiga  toxin, Heat-stable enterotoxin ( E.  coli  ST), colibactin, BFT ( B.  fragilis  toxin) or any toxin described in Henkel et al., (Toxins from Bacteria in EXS. 2010; 100: 1-29). In a particular embodiment, said toxin is Shiga toxin. 
     In another embodiment, the nucleic acid of interest encodes a gene or group of genes encoding one or more exogenous enzyme(s) which result(s) in a genetic modification. 
     In a particular embodiment, said nucleic acid of interest is a gene encoding a base-editor or a prime-editor. 
     In some embodiments, the genetic modification is made with one or more of the following enzymes and systems. 
     Cytosine base editors (CBE) and Adenosine base editors (ABE), as described in Rees et al. (2018)  Nat Rev Genet  19:770-788, which is hereby incorporated by reference. 
     So far there is seven types of DNA base editors described:
     Cytosine Base Editor (CBE) that convert C:G into T:A (Komor et al. (2016)  Nature  533:420-424)   Adenine Base Editor (ABE) that convert A:T into G:C (Gaudelli et al. (2017)  Nature  551:464-471)   Cytosine Guanine Base Editor (CGBE) that convert C:G into G:C (Chen et al. (2020) Biorxiv “Precise and programmable C:G to G:C base editing in genomic DNA”; Kurt et al. (2020)  Nat. Biotechnol . “CRISPR C-to-G base editors for inducing targeted DNA transversions in human cells”)   Cytosine Adenine Base Editor (CABE) that convert C:G into A:T (Zhao et al. (2020)  Nature Biotechnol . “New base editors change C to A in bacteria and C to G in mammalian cells”)   Adenine Cytosine Base Editor (ACBE) that convert A:T into C:G (WO2020181180)   Adenine Thymine Base Editor (ATBE) that convert A:T into T:A (WO2020181202)   Thymine Adenine Base Editor (TABE) that convert T:A into A:T (WO2020181193, WO2020181178, WO2020181195)   

     Base editors differ in the base modification enzymes. CBE rely on ssDNA cytidine deaminase among which: APOBEC1, rAPOBEC1, APOBEC1 mutant or evolved version (evoAPOBEC1), and APOBEC homologs (APOBEC3A (eA3A), Anc689), Cytidine deaminase 1 (CDA1), evoCDA1, FERNY, evoFERNY. 
     ABE rely on deoxyadenosine deaminase activity of a tandem fusion TadA-TadA* where TadA* is an evolved version of TadA, an E.coli tRNA adenosine deaminase enzyme, able to convert adenosine into Inosine on ssDNA.TadA* include TadA-8a-e and TadA-7.10. 
     Except from base modification enzyme there has been also modifications implemented to base editor to increase editing efficacy, precision and modularity:
     the addition of one or two uracil DNA glycosylase inhibitor domain (UGI) to prevent base excision repair mechanism to revert base edition   the addition of Mu-GAM that decrease insertion-deletion rate by inhibiting Non-homologous end joining mechanism in the cell (NHEJ)   the use of nickase active Cas9 (nCas9 D10A) that, by creating nicks on the non-edited strand favor its repair and consequently the fixation of the edited base   the use of diverse Cas proteins from for example different organisms, mutants with different PAM motifs or different fidelity or different family (e.g. Cas12a).   

     Non-limiting examples of DNA based editor proteins include BE1, BE2, BE3, BE4, BE4-GAM, HF-BE3, Sniper-BE3, Target-AID, Target-AID-NG, ABE, EE-BE3, YE1-BE3, YE2-BE3, YEE-BE3, BE-PLUS, SaBE3, SaBE4, SaBE4-GAM, Sa(KKH)-BE3, VQR-BE3, VRER-BE3, EQR-BE3, xBE3, Cas12a-BE, Ea3A-BE3, A3A-BE3, TAM, CRISPR-X, ABE7.9, ABE7.10, ABE7.10*, xABE, ABESa, VQR-ABE, VRER-ABE, Sa(KKH)-ABE, ABE8e, SpRY-ABE, SpRY-CBE, SpG-CBE4, SpG-ABE, SpRY-CBE4, SpCas9-NG-ABE, SpCas9-NG-CBE4, enAsBE1.1, enAsBE1.2, enAsBE1.3, enAsBE1.4, AsBE1.1, AsBE1.4, CRISPR-Abest, CRISPR-Cbest, eA3A-BE3, AncBE4. 
     Cytosine Guanine Base Editors (CGBE) consist of a nickase CRISPR fused to:
     [a] A cytosine deaminase (rAPOBEC) and base excision repair proteins (e.g. rXRCC1) (Chen et al. (2020)  Biorxiv  “Precise and programmable C:G to G:C base editing in genomic DNA”).   [b] A rat APOBEC1 variant (R33A) protein and an E. coli-derived uracil DNA N-glycosylase (eUNG) (Kurt et al. (2020)  Nat. Biotechnol . “CRISPR C-to-G base editors for inducing targeted DNA transversions in human cells”).   

     Cytosine Adenine Base Editors (CABE) consist of a Cas9 nickase, a cytidine deaminase (e.g. AID), and a uracil-DNA glycosylase (Ung) (Zhao et al. (2020)  Nature Biotechnol . “New base editors change C to A in bacteria and C to G in mammalian cells”). 
     ACBE include a nucleic acid programmable DNA-binding protein and an adenine oxidase (WO2020181180). 
     ATBE consist of a Cas9 nickase and one or more adenosine deaminase or an oxidase domain (WO2020181202). 
     TABE consist of a Cas9 nickase and an adenosine methyltransferase, a thymine alkyltransferase, or an adenosine deaminase domain (WO2020181193, WO2020181178, WO2020181195). 
     Base editor molecules can also consist of two or more of the above listed editor enzymes fused to a Cas protein (e.g. combination of an ABE and CBE). These biomolecules are named dual base editors and enable the editing of two different bases (Grunewald et al. (2020)  Nature Biotechnol . “A dual-deaminase CRISPR base editor enables concurrent adenine and cytosine editing”; Li et al. (2020)  Nature Biotechnol . “Targeted, random mutagenesis of plant genes with dual cytosine and adenine base editors”). 
     Prime editors (PE), as described in  Anzalone  et al. (2019)  Nature  576:149-157, which is hereby incorporated by reference, consist of nCas9 fused to a reverse transcriptase used in combination with a prime editing RNA (pegRNA, a guide RNA that includes a template region for reverse transcription). 
     Prime Editing allows introduction of insertions, deletions (indels) and 12 base-to-base conversions. Prime editing relies on the ability of a reverse transcriptase (RT), fused to a Cas nickase variant, to convert RNA sequence brought by a prime editing guide RNA (pegRNA) into DNA at the nick site generated by the Cas protein. The DNA flap generated from this process is then included or not in the targeted DNA sequence. 
     Prime editing systems include:
     a Cas nickase variant such as Cas9-H840A fused to a reverse transcriptase domain such as M-MLV RT or its mutant version (M-MLV RT(D200N), M-MLV RT(D200N/L603W), M-MLV RT(D200N/L603W/T330P/ T306K/W313F)   a prime editing guide RNA (pegRNA)   

     To favor editing the prime editing system can include the expression of an additional sgRNA targeting the Cas nickase activity towards the non-edited DNA strand ideally only after the resolution of the edited strand flap by designing the sgRNA to anneal with the edited strand but not with the original strand. 
     Non-limiting examples of prime editing systems include PE1, PE1-M1, PE1-M2, PE1-M3, PE1-M6, PE1-M15, PE1-M3inv, PE2, PE3, PE3b. 
     Cas9 Retron precISe Parallel Editing via homologY (‘CRISPEY’), a retron RNA fused to the sgRNA and expressed together with Cas9 and the retron proteins including at least the reverse transcriptase (Sharon etal. (2018)  Cell  175:544-557.e16). 
     The SCRIBE strategy: a retron system expressed in combination with a recombinase promoting the recombination of single stranded DNA, also known as single stranded annealing proteins (SSAPs) (Farzadfard &amp; Lu (2014)  Science  346:1256272). Such recombinases include but are not limited to phage recombinases such as lambda red, recET, Sak, Sak4, and newly described SSAPs described in Wannier et al. (2020)  Proc Natl Acad Sci USA  117(24):13689-13698 which is hereby incorporated by reference. 
     The targetron system based on group II introns described in Karberg et al. (2001)  Nat Biotechnol  19:1162-7, which is hereby incorporated by reference, and which has been adapted to many bacterial species. 
     Other retron based gene targeting approaches are described in Simon et al. (2019)  Nucleic Acids Res  47:11007-11019, which is hereby incorporated by reference. 
     In various embodiments, the nucleic acid of interest encodes fusion proteins comprising a Cas, in particular Cas9 (e.g., a Cas9 nickase), domain and a deaminase domain. In some embodiments, the fusion protein comprises a Cas, in particular Cas9, and a cytosine deaminase enzyme, such as APOBEC enzymes, or adenosine deaminase enzymes, such as ADAT enzymes, for example as disclosed in U.S. Pat. Publ. 2015/0166980, which is hereby incorporated by reference. In one embodiment, the deaminase is an ACF1/ASE deaminase. 
     In various embodiments, the APOBEC deaminase is selected from the group consisting of APOBEC1 deaminase, APOBEC2 deaminase, APOBEC3A deaminase, APOBEC3B deaminase, APOBEC3C deaminase, APOBEC3D deaminase, APOBEC3F deaminase, APOBEC3G deaminase, and APOBEC3H deaminase. In various embodiments, the fusion protein comprises a Cas9 domain, a cytosine deaminase domain, and a uracil glycosylase inhibitor (UGI) domain. 
     In one embodiment, the deaminase is an adenosine deaminase that deaminate adenosine in DNA, for example as disclosed in U.S. Pat. 10,113,163, which is hereby incorporated by reference. In some embodiments, the fusion proteins further comprise an inhibitor of base repair, such as, a nuclease dead inosine specific nuclease (dISN), for example as disclosed in U.S. Pat. 10,113,163. In various embodiments, the nucleic acid of interest encodes fusion proteins comprising a catalytically impaired Cas, in particular Cas9, endonuclease fused to an engineered reverse transcriptase, programmed with a prime editing guide RNA (pegRNA) that both specifies the target site and encodes the desired edit, for example as described in Anzalone et al. (2019)  Nature  576: 149-157, which is hereby incorporated by reference. 
     In some embodiments, the genetic modification is made at the RNA level. RNA base editing is based on the same principle as DNA base editing: an enzyme catalyzing the conversion of a RNA base into another must be brought close to the target base to perform its conversion locally. In one embodiment, the enzyme used for RNA editing is an adenosine deaminase from ADAR family that converts Adenosine into Inosine in dsRNA structure. Several seminal studies used this specificity for dsRNA and fused the ADAR deaminase domain (ADAR DD ) to an antisense oligo in order to program local RNA base editing. More recently the ability of some CRISPR-Cas systems to bind RNA molecules was repurposed into RNA editing. Using catalytically dead Cas13b enzyme (dPspCas13b) fused to a hyperactive mutant of ADAR2 deaminase domain (ADAR2DD-E488Q for REPAIRv1 and ADAR2 DD -E488Q-T375G for REPAIRv2) Cox et al improved specificity and efficiency compare to previous RNA editing strategies. Non-limiting examples of RNA based editor proteins include REPAIRv1, REPAIRv2. 
     In some embodiments, the nucleic acid of interest encodes other programmable nucleases. These include an engineered TALEN (Transcription Activator-Like Effector Nuclease) and variants, engineered zinc finger nuclease (ZFN) variants, natural, evolved or engineered meganuclease or recombinase variants, and any combination or hybrids of programmable nucleases. Thus, the programmable nucleases provided herein may be used to selectively modify DNA encoding a gene of interest such as, for example, a toxin gene, a virulence factor gene, an antibiotic resistance gene, a remodeling gene or a modulatory gene (cf. WO2014124226 and US2015/0064138). 
     In a particular embodiment, said payload comprises or consists of the nucleic acid sequence SEQ ID NO: 33. In an alternative embodiment, said payload comprises or consists of the nucleic acid sequence SEQ ID NO: 42. 
     In an alternative embodiment, the nucleic acid of interest encodes a therapeutic protein. In another embodiment, the nucleic acid of interest encodes an antisense nucleic acid molecule. 
     The present disclosure thus also provides a production cell line, as defined above, comprising a helper prophage as defined above, and further comprising a phagemid comprising or consisting of the payload as defined above, in particular of the nucleic acid sequence SEQ ID NO: 33 or of the nucleic acid sequence SEQ ID NO: 42. 
     In a particular embodiment, the bacterial delivery vehicle provided herein comprises chimeric STF of sequence SEQ ID NO: 11 and chimeric gpJ variant of sequence SEQ ID NO: 27, and further comprises a payload which comprises or consists of the nucleic acid sequence SEQ ID NO: 33.

     A microbiome may comprise a variety of endogenous bacterial species, any of which may be targeted in accordance with the present disclosure. In some embodiments, the genus and/or species of targeted endogenous bacterial cells may depend on the type of bacteriophages being used for preparing the bacterial delivery vehicles. For example, some bacteriophages exhibit tropism for, or preferentially target, specific host species of bacteria. Other bacteriophages do not exhibit such tropism and may be used to target a number of different genus and/or species of endogenous bacterial cells. 
     Examples of bacterial cells include, without limitation, cells from bacteria of the genus  Yersinia spp., Escherichia spp., Klebsiella spp., Acinetobacter spp., Bordetella spp., Neisseria spp., Aeromonas spp., Franciesella spp., Corynebacterium spp., Citrobacter spp., Chlamydia spp., Hemophilus spp., Brucella spp., Mycobacterium spp., Legionella spp., Rhodococcus spp., Pseudomonas spp., Helicobacter spp., Vibrio spp., Bacillus spp., Erysipelothrix spp., Salmonella spp., Streptomyces spp., Streptococcus spp., Staphylococcus spp., Bacteroides spp., Prevotella spp., Clostridium spp., Bifidobacterium spp., Clostridium spp., Brevibacterium spp., Lactococcus spp., Leuconostoc spp., Actinobacillus spp., Selnomonas spp., Shigella spp., Zymonas spp., Mycoplasma spp., Treponema spp., Leuconostoc spp., Corynebacterium spp., Enterococcus spp., Enterobacter spp., Pyrococcus spp., Serratia spp., Morganella spp., Parvimonas spp., Fusobacterium spp., Actinomyces spp., Porphyromonas spp., Micrococcus spp., Bartonella spp., Borrelia spp., Brucelia spp., Campylobacter spp., Chlamydophilia spp., Cutibacterium (formerly Propionibacterium) spp., Ehrlichia spp., Haemophilus spp., Leptospira spp., Listeria spp., Mycoplasma spp., Nocardia spp., Rickettsia spp., Ureaplasma spp., and Lactobacillus spp , and a mixture thereof. 
     Thus, bacterial delivery vehicles may target (e.g., specifically target) a bacterial cell from any one or more of the foregoing genus of bacteria to specifically deliver the payload of interest according to the disclosure. 
     In an embodiment, the targeted bacteria can be selected from the group consisting of  Yersinia spp., Escherichia spp., Klebsiella spp., Acinetobacter spp., Pseudomonas spp., Helicobacter spp., Vibrio spp, Salmonella spp., Streptococcus spp., Staphylococcus spp., Bacteroides spp., Clostridium spp., Shigella spp., Enterococcus spp., Enterobacter spp., and Listeria spp . 
     In some embodiments, targeted bacterial cells of the present disclosure are anaerobic bacterial cells (e.g., cells that do not require oxygen for growth). Anaerobic bacterial cells include facultative anaerobic cells such as but not limited to  Escherichia coli ,  Shewanella oneidensis  and  Listeria . Anaerobic bacterial cells also include obligate anaerobic cells such as, for example,  Bacteroides  and  Clostridium  species. In humans, anaerobic bacteria are most commonly found in the gastrointestinal tract.

     Pharmaceutical or Veterinary Composition 
     The present disclosure also provides a pharmaceutical or veterinary composition comprising the bacterial delivery vehicle as defined in the section “Bacterial delivery vehicle” above and a pharmaceutically acceptable carrier. 
     Generally, for pharmaceutical use, the bacterial delivery vehicles may be formulated as a pharmaceutical preparation or composition comprising at least one bacterial delivery vehicle and at least one pharmaceutically acceptable carrier, diluent or excipient, and optionally one or more further pharmaceutically active compounds. Such a formulation may be in a form suitable for oral administration, for parenteral administration (such as by intravenous, intramuscular or subcutaneous injection or intravenous infusion), for topical administration, for administration by inhalation, by a skin patch, by an implant, by a suppository, etc. In a particular embodiment, said composition is for oral administration. Such administration forms may be solid, semi-solid or liquid, depending on the manner and route of administration. For example, formulations for oral administration may be provided with an enteric coating that will allow the synthetic bacterial delivery vehicles in the formulation to resist the gastric environment and pass into the intestines. More generally, synthetic bacterial delivery vehicle formulations for oral administration may be suitably formulated for delivery into any desired part of the gastrointestinal tract. In addition, suitable suppositories may be used for delivery into the gastrointestinal tract. Various pharmaceutically acceptable carriers, diluents and excipients useful in bacterial delivery vehicle compositions are known to the skilled person 
     The pharmaceutical or veterinary composition according to the disclosure may further comprise a pharmaceutically acceptable vehicle. A solid pharmaceutically acceptable vehicle may include one or more substances which may also act as flavouring agents, lubricants, solubilisers, suspending agents, dyes, fillers, glidants, compression aids, inert binders, sweeteners, preservatives, dyes, coatings, or tablet- disintegrating agents. Suitable solid vehicles include, for example calcium phosphate, magnesium stearate, talc, sugars, lactose, dextrin, starch, gelatin, cellulose, polyvinylpyrrolidone, low melting waxes and ion exchange resins. 
     The pharmaceutical or veterinary composition may be prepared as a sterile solid composition that may be suspended at the time of administration using sterile water, saline, or other appropriate sterile injectable medium. The pharmaceutical or veterinary compositions disclosed herein may be administered orally in the form of a sterile solution or suspension containing other solutes or suspending agents (for example, enough saline or glucose to make the solution isotonic), bile salts, acacia, gelatin, sorbitan monoleate, polysorbate 80 (oleate esters of sorbitol and its anhydrides copolymerized with ethylene oxide) and the like. The particles according to the disclosure can also be administered orally either in liquid or solid composition form. Compositions suitable for oral administration include solid forms, such as pills, capsules, granules, tablets, and powders, and liquid forms, such as solutions, syrups, elixirs, and suspensions. Forms useful for enteral administration include sterile solutions, emulsions, and suspensions. 
     The bacterial delivery vehicles disclosed herein may be dissolved or suspended in a pharmaceutically acceptable liquid vehicle such as water, an organic solvent, a mixture of both or pharmaceutically acceptable oils or fats. The liquid vehicle can contain other suitable pharmaceutical additives such as solubilisers, emulsifiers, buffers, preservatives, sweeteners, flavouring agents, suspending agents, thickening agents, colours, viscosity regulators, stabilizers or osmo-regulators. Suitable examples of liquid vehicles for oral and enteral administration include water (partially containing additives as above, e.g. cellulose derivatives, preferably sodium carboxymethyl cellulose solution), alcohols (including monohydric alcohols and polyhydric alcohols, e.g. glycols) and their derivatives, and oils (e.g. fractionated coconut oil and arachis oil). For parenteral administration, the vehicle can also be an oily ester such as ethyl oleate and isopropyl myristate. Sterile liquid vehicles are useful in sterile liquid form compositions for enteral administration. The liquid vehicle for pressurized compositions can be a halogenated hydrocarbon or other pharmaceutically acceptable propellant.

     It has been shown that a chimera between lambda STF and V10 STF (originating from a prophage found in 0157 strains), said chimera being of sequence SEQ ID NO: 15, is able to target 0157 strains with high efficiency in vitro by recognizing and degrading the 0157 antigen group IV capsule. However, initial in vivo experiments showed that lambda packaged phagemids containing the V10 chimeric STF did not deliver with high efficiency into 0157 strains colonizing the mouse gut. Efficiencies of delivery in this mouse model were, on average, 20% and the delivery was not improved by increasing the dosage given to the mouse (MOI). 
     One possible reason for this observation was that the chimeric lambda particles containing V10 fusions were stable in in vitro conditions, where delivery and killing experiments were done in the presence of known reagents (for instance, LB), but lost part of their activity once they passed through the mouse gut. 
     It had been observed that wild-type lambda particles are able to pass and replicate in the gut suggesting that some part of the engineering process to generate the lambda-V10 fusion had rendered it at least less stable and partly susceptible to degradation in in vivo conditions. Apart from the lambda STF-V10 fusion, the lambda particles used in these experiments have also been engineered at the gpJ level to modify its primary receptor, and contain the 1A2 gpJ variant (and are thus called herein 1A2-V10 particles). Thus, it was possible that either the 1A2 gpJ variant and/or the STF-V10 fusion were the sources of reduced stability in in vivo conditions. 
     In vitro assays were set up to differentiate between 1A2 gpJ activity and STF-V10 activity based on the fact that, for some strains, the presence of a functional STF is dispensable for injection, as is the case for the MG1655 K-12 strain. Since the 1A2 gpJ variant recognizes the OmpC receptor of 0157 strains, but not that of MG1655, an MG1655 variant was engineered in which the OmpC receptor was replaced to encode that of the 0157 variant. This strain was called MG1656-OmpCO157. On the other hand, efficient delivery in 0157 strains is completely dependent on the presence of a functional STF containing V10. Hence, by exposing the 1A2-V10 packaged phagemids to different conditions and evaluating the gpJ versus STF-V10 activity in vitro, it was possible to determine which part of the packaged phagemid was unstable. 
     The 1A2-V10 packaged phagemids were then exposed to simulated intestinal fluid (SIF) in the presence or absence of pancreatin (which contains the digestive enzymes trypsin and chymotrypsin) and bile salts. Specifically, packaged phagemids were produced, diluted 1:100 in the buffer of choice and incubated at 37° C. for 3 hours. After that, the packaged phagemids were directly titrated on MG1656-OmpCO157 and H10 (O157)-delta-stx strains. As a control, the wild-type lambda packaged phagemid produced with CYC3 strains was also exposed to the same conditions. H10-delta-stx is a variant of 0157 strain for which the stx gene has been deleted. Briefly, the wild-type H10 strain was transduced with packaged lambda phagemids containing a lambda-V10 STF chimera and a packaged circuit encoding a Cpf1 nuclease programmed to target the stx2 gene. After transduction, survivor colonies were checked by PCR to verify the presence or absence of the stx gene and only colonies with stx gene deleted were kept. 
     As can be seen in  FIG.  1   , the wild-type lambda particle produced with CYC3 strains was stable under any conditions, as the titers remained the same across all experiments. However, for the 1A2-V10 variant, a constant gpJ activity (central bars in  FIG.  1   ) was observed, which indicates that this gpJ variant was not degraded in the presence of pancreatin. Finally, the titers of the 1A2-V10 dropped by a factor of 2 log when titrated in H10-delta-stx (0157) strains only in the presence of pancreatin. Bile salts by themselves did not affect the activity of the packaged phagemids. These results clearly demonstrate that the STF-V10 chimera is at least partially degraded in the presence of pancreatin. 
     It was hypothesized that the source of reduced stability was not in the V10 moiety itself, but in the way the fusion with the lambda STF was generated. Further, it was hypothesized that although no linker amino acids were inserted in the initial lambda STF-V10 chimera, the context of the fusion was not natural, and hence, had not been selected for stability in the presence of proteolytic enzymes. To test this hypothesis, two types of lambda STF-V10 chimeras were generated: the first type contains point mutations in phenylalanine (F) and lysine (K) residues present in the fusion point between lambda STF and V10 STF ( FIG.  2   ); for the second type, a more detailed structural analysis was performed. Structural homology analyses with the original V10 fusion showed a crystallized STF with high identity to the V10 moiety (PDB ID: 5W6S): this STF contains a short helix at its N-terminus which has a homolog in V10, but that was not included in the original lambda STF-V10 chimera. The helix forms a very tight bundle that “fastens” the domain right after it in the crystal structure. Based on the delivery efficiency results that were obtained with the original lambda STF-V10 version, this helix may not be important for activity but it may be important for stability since it may confer a proper folding where exposed trypsin- and chymotrypsin-accessible residues are buried ( FIG.  2   ). 
     Accordingly, three lambda-STF-V10 fusion variants were constructed: V10-[FA] (SEQ ID NO: 9), where a lysine (K) residue was exchanged by an alanine (A); V10-[AAH] (SEQ ID NO: 10), where an FKF tripeptide was exchanged to AAH tripeptide; and V10-Helix (SEQ ID NO: 11), where the short 10-amino acid helix bundle GSATDVMIQLA (SEQ ID NO: 7) was included as part of the chimeric protein just after the insertion site. The insertion site with the lambda STF, GAGENS (SEQ ID NO: 5), was not changed for any of the variants. 
     The three variants were then exposed to buffer at different pH values (5.0 and 6.8) in the presence or absence of pancreatin as detailed for the original lambda STF-V10 fusion above. As can be seen in  FIG.  3   , all variants showed some degree of resistance to pancreatin treatment: the V10-[FA] and V10-[AAH] variants showed between 1 and 1.5 log higher particle levels than the original V10 counterpart, although the stability was not complete and was dependent on pH. However, the V10-Helix variant showed an apparent complete resistance to digestive proteases at any pH tested. Taken together, the results showed that one can engineer lambda STF-V10 variants that are resistant to digestive proteases by only engineering the linker region, and that are good candidates for in vivo use, with V10-Helix showing highly positive results in vitro. 
     In vivo studies were next conducted. It was difficult to deliver 0157 strains in vivo at a decent efficiency (max 40%, but typically under 20%) and interestingly, the delivery was not improved by increasing the MOI administered to the mouse. However, delivery was observed with the same vector while using a strain deleted for the 0157 antigen (ΔwaaJ mutants). Based on this result, it was possible that the V10 activity somehow may not survive the transit through the GIT. 
     In vivo assays were conducted to measure the kinetics of shedding of packaged phagemids with 1A2 gpJ and chimeric lambda STF-V10 after oral administration to streptomycin-treated, uncolonized BALB/c mice as well as the residual V10 activity. The specific V10 activity was evaluated by comparing transduction efficiencies on H10Δstx, where 1A2 and V10 are both needed and MG-ompC_O157 where only 1A2 is required. Packaged phagemids were produced at high titer and given to 3 mice in sucrose-bicarbonate buffer to reduce the stomach acidity and to help packaged phagemids to reach the intestine. Stool samples were collected at T0, T2h, T4h, T6h and T8h, and resuspended in PBS. After centrifugation, supernatants containing shed packaged phagemids were used in transduction assays against H10Δstx and MG-ompC_O157. 
     Interestingly, as can be seen in  FIG.  4   , the initial dose of packaged phagemid contained approximately 10% of the particles with V10 activity. Most of the 1A2 activity could be recovered between 6 to 8 hours after oral gavage, which indicates that this gpJ variant is not degraded after transit through the entire Gastrointestinal Tract (GIT). However, the estimated titers measuring the V10 activity were very low. Less than 1% of the recovered packaged phagemids kept their V10 functionality. This result indicates that at least 90% of the packaged phagemid with 1A2 gpJ and chimeric lambda STF-V10 lose their V10 activity in the GIT. The presence of numerous proteolytic enzymes (trypsin and chymotrypsin) secreted by the pancreas in the gut may be responsible for this degradation. This experiment finally demonstrates that 1A2-V10 can survive through the GI tract but loses an important part of its V10 activity which would explain why one cannot deliver in 0157 strains at high efficiency. 
     Following on from this experiment and the result of in vitro stability testing of 3 new lambda-STF-V10 fusion variants, 2 variants that seemed to better resist the digestive proteases were used: lambda-STF-V10-[FA] and lambda-STF-V10-[Helix], disclosed above. Indeed, in vitro experiments have shown that these packaged phagemids (also called eligobiotics or EB) seemed able to resist in pancreatin-containing medium at least 1h without losing their capacity to deliver into strains where V10 activity is required. This was especially true for the lambda-STF-V10-[Helix] variant. Then, in the exact same conditions as with the original 1A2-V10, the inventors assessed the residual activity of V10 after passage through the entire GI tract of uncolonized BALB/c mice. 
     As can be seen on  FIG.  5   , V10 activity of the variant 1A2-V10-[FA] was approximately at 1% after passage through the gut. As opposed to this observation, the new 1A2-V10-[Helix] showed a V10 activity approximately similar to the total activity of this packaged phagemid after passage through the GIT. These data indicate that 1A2-V10-[Helix] could perform optimally in vivo due to the high stability of its V10 activity (as opposed to the original version of 1A2-V10). To further confirm this stability, a simplified pharmacokinetics study was conducted in mice, where the shedding of the 1A2-V10-[Helix] over time was observed, following oral gavage of uncolonized BALB/c mice with a single dose of this packaged phagemid (administered as a 1:1 mixture with a sucrose/bicarbonate buffer). 
     As shown in  FIG.  6   , the STF activity (required to enter into H10 but not into MG1656) was just as stable over time as the Tip/overall capside functionality, as indicated by the identical pattern of shedding in the stool. 
     In another experiment, the in vivo delivery of the two new versions through plasmid curing was studied. The lambda-STF-V10-[Helix] and lambda-STF-V10-[FA] packaged phagemids were administered (2 doses, 6 h apart) targeting one part of the pRFP plasmid into mice colonized with H10Δstx/pRFP. Assuming that the payload is fully effective (100% cutting efficacy once expressed in the cell), the delivery can be calculated as the ratio of bacteria that lost the target plasmid over the total number of bacteria. Practically, the plasmid carries a kanamycin resistance gene; this makes it easier to check for colonies that kept versus lost the plasmid by simply patching streptomycin-resistant bacteria onto Kan plates. 
     As can be seen on  FIG.  7   , the curing efficiency was great with this mixture of packaged phagemids as most of the mice displayed a curing percentage of 80% or more (9 mice out of 10). Even though a great peak was observed after a single administration at t = 6 h, the peak of curing efficacy was higher at 24 hours post-treatment likely reflecting the interest of a second administration, although this may be due to transit time variations between animals. Another interesting observation is that pRFP curing (i.e., sensitivity to kanamycin) was still visible at T24h and T48h whereas payload delivery (i.e., resistance to chloramphenicol) had strongly decreased. This indicates that the curing method could give a more stable view of delivery/nuclease efficacy over time. The results clearly demonstrate that the mixture of new packaged phagemids tested is much more capable of targeting strains of interest in the mouse intestine. 
     In order to optimize for phagemids, PCRs were conducted on several clones from the feces to discriminate between lambda-STF-V10-[Helix] and lambda-STF-V10-[FA]: out of 38 tested clones, 71% had received the payload from lambda-STF-V10-[Helix], indicating that this version was significantly efficient under in vivo conditions. 
     According to previous results, a decolonization experiment in vivo of the STEC strain H10WT with the new mutant 1A2-V10-[Helix] was conducted. In order to avoid colonization rebound immediately after treatment with packaged phagemids, it was decided to remove the antibiotic pressure (streptomycin) that was used to clear and maintain a niche for Enterobacteriaceae in the gut of mice with conventional specific-pathogen-free flora. Mice were treated with 5 doses of the packaged phagemid, 2 days apart, and compared with a control group treated with 5 doses of buffer (sucrose Bicarbonate). 
     As can be observed in  FIGS.  8  and  9    on the control group, the colonization was not totally stable overtime. A slow decrease day after day can be seen from D6 to D12. However, the buffer did not seem to have an impact on the colonization level. In contrast, the colonization level of the STEC strains presented a great response to treatment. Indeed, a 2 logs reduction was observed after the first dose and more than 3 logs after the second for 4 mice out of 5. After the full 5-dose regimen (D7), a total of 4 logs of killing was obtained. Interestingly, no rebound of the colonization was observed after the last treatment. 
     To check for a potential resistant population to the packaged phagemids (natural or acquired) at the end of the experiment, surviving colonies on D7/D8 were patched and a transduction experiment was carried out. Interestingly, no resistance (entry or nuclease) was observed in this experiment. Taken together, the results described herein show an increased efficacy of variants, such as the variant 1A2-V10-[Helix] to decolonize STEC strains from the mouse gut. 
     Example 2 
     To test if the approach followed with the lambda-STF-V10 chimeric STF in Example 1 above was generalizable to other STF chimeras, a second set of experiments was performed. In this case, a functional chimeric STF was engineered between lambda STF and the K5 tailspike, called lambda-K5 (SEQ ID NO: 37) which has been described in the literature to infect K5-encapsulated E. coli strains and for which a crystal structure is available [11]. The same approach as for lambda-V10 chimera was followed, including the insertion point in the lambda STF protein (GAGENS (SEQ ID NO: 5)). In this case, the readout strain for K5 STF activity was LMR_503 and the readout for gpJ activity was MG1656-OmpCO157, as explained before. Packaged phagemids harboring the 1A2 gpJ (SEQ ID: 27) and the lambda-K5 STF were produced and titrated in both LMR_503 or MG1656-OmpCO157 after treatment with or without pancreatin at pH 6.8. 
     As can be seen in  FIG.  10   , although the lambda-K5 STF chimera was completely functional as measured by its ability to inject into the LMR_503 strain in PBS, it was not very stable in the presence of pancreatin, showing up to 4-log loss in the number of functional particles. This was similar to what was observed for the lambda-STF-V-10 chimeric STF. 
     Next, the crystal structure was analyzed for the original K5 STF (PDB ID: 2X3H) and it was observed that it also contained a three helical bundle at its N-terminus. However, as opposed to the V10 structure, the helical bundle of K5 was capped by a turn, which in the lambda-K5 STF was directly at the fusion point. It was hypothesized that this non-natural insertion point may be the cause for the pancreatin reduced stability observed. To test this hypothesis, several lambda-K5 variants were constructed in which the fusion point was modified to contain different versions of the helical bundle.
     Lambda K5 5.0 (SEQ ID NO: 13): contains part of the helical bundle from V10 (GSATDVMIQL (SEQ ID NO: 6)) fused to the K5 STF without its original helical bundle   Lambda K5 5.1 (SEQ ID NO: 14): contains the helical bundle from V10 (GSATDVMIQLA (SED ID NO: 7)) fused to the K5 STF without its original bundle   

     Packaged phagemids harboring the 1A2 gpJ and each of the K5 helix chimeras were produced and titrated on MG1656-OmpCO157 or LMR 503, as explained above. 
       FIGS.  11  and  12    show that the variants containing V10 helix versions K5 5.0 and K5 5.1 were mostly resistant to pancreatin treatment, as there was only 1 log loss compared to other STF fusions. It is also important to note that no functional differences in terms of titers were observed for any of the K5 variants constructed, which suggests a high degree of flexibility in terms of linkers to be used when creating non-homologous STF chimeras. 
     It has thus been shown that there was no correlation between function (injection in a given strain) and stability, and that the latter was dependent on the amino acid content of the fusion point. Additionally, the inventors showed that the sequence GSATDVMIQL(A) (SEQ ID NO: 6 and 7) originating from V10 Helix can be used as a pancreatin-resistant linker even in proteins that contain no homology to V10 STF (K5 STF) and protect the new chimera from degradation by pancreatin. 
     Example 3 
     Alternative pancreatin-resistant linkers conferring stability to a lambda STF-K5 chimera were designed from a STF protein having homology, at its C-terminal portion, with the C-terminal portion of the K5 STF starting at amino acid G62, namely candidate STF protein from  scherichia phage  ZG49 (SEQ ID NO: 43 and SEQ ID NO: 44). 
     An analysis of this ZG49 STF protein using HHPRED software (Söding et al. (2005) Nucleic Acids Res. 33:W244-8) showed that it contains a helical bundle from amino acid 212 to amino acid 217. This helical bundle was included in the linkers designed by the inventors. More particularly, these linkers comprise the amino acid sequence located between amino acids G210 or D211 and amino acid E272 of the ZG49 phage STF protein. They are typically of sequence SEQ ID NO: 34 or SEQ ID NO: 36. 
     Two chimeric STFs were then built that contain the N-terminus of Lambda STF up to amino acid sequence GAGENS (SEQ ID NO: 5), followed by the linker designed above of sequence SEQ ID NO: 34 or SEQ ID NO: 36, and followed by the K5 moiety starting from position G62. The DNA sequences of the designed linkers were recoded for expression in Escherichia coli and were respectively of sequence SEQ ID NO: 35 and SEQ ID NO: 37. The two chimeric STFs were called K5 9.0 (for linker starting at position G210, SEQ ID NO: 38 and SEQ ID NO: 39) and K5 9.1 (for linker starting at position D211, SEQ ID NO: 40 and SEQ ID NO: 41) and only differ in the presence or absence, respectively, of a glycine at the start of the linker. 
     The production and pancreatin tests of both chimeric STFs were done as shown in Examples 1 and 2, and showed that the use of a linker designed from a STF protein having homology at this C-terminal portion with the K5 STF also provided pancreatin resistance to the chimeric STFs, and even improved the pancreatin resistance of the chimera as compared to K5 5.0 and K5 5.1 ( FIG.  15   ). 
     Finally, in vivo assays were performed to attempt decolonization of the LMR_503 strain, which should be targeted in the gut only if the chimeric STF is resistant to proteolytic enzymes, as has been shown in Example 2. To do this, 10 BALB/c mice were treated with streptomycin and colonized with strain LMR_503. An Eligobiotic® harboring the A8 gpJ and the chimeric K5 9.1 STF was produced carrying a plasmid (p775, SEQ ID NO: 45) encoding a nuclease and a guide targeting the ctx gene found in strain LMR_503. The decolonization assay was identical to that described for strain H10WT, following a single dose of Eligobiotic® ( FIG.  16   ). 
     A 2.6 log median reduction in strain levels was observed after treatment with Eligobiotic®, which shows that the engineering of the K5 9.1 STF was successful, and that K5 9.1 STF was able to withstand proteolytic degradation in the mouse gut. 
     The inventors thus showed that other linkers could be designed to confer pancreatin resistance to chimeric RBP proteins. In particular, it is herein shown that the sequences SEQ ID NO: SEQ ID NO: 34 and SEQ ID NO:36 designed from the ZG49 phage STF protein can be used as a pancreatin-resistant linker to protect chimera comprising a lambda STF N-terminal portion and a K5 STF C-terminal portion from degradation by pancreatin. 
     Example 4 
     To evaluate the effect of DNA payload size on the number of payloads packaged in Eligobiotics®, 3 different payloads were used to produce Eligobiotics® as summarized in Table 1.

     After fermentation, lysis (3 h incubation at 37° C. with 0.1% Triton X-100, 2000 U/L Benzonase) and clarification on a Zeta Plus Capsule (3M), the Eligobiotics® were purified by anion exchange chromatography on a Sartobind Q capsule (Sartorius). This initial purification was followed by a buffer exchange and concentration step by tangential flow filtration on a Pellicon 2 minicassette Biomax 300 kDa (Millipore). A final polishing step of size exclusion chromatography on Sepharose 6FF resin (GE Healthcare) was performed to yield the purified Eligobiotics®. 
     Analysis of the Eligobiotics®’s DNA content was performed by analytical ultracentrifugation in a Beckman Coulter Optima AUC using an AN50Ti rotor at 6 krpm. The sedimentation coefficients of different particles present in solution for each EB batch were extracted from sedimentation velocity data (acquired at 260 and 280 nm). 
     Based on the molecular weight calculated from their sedimentation coefficient and their 260/280 nm ratios, the different populations of particles detected could be separated as Eligobiotics® containing either 3 copies (centered on 290 S) or 4 copies (centered on 330-340 S) of the payload ( FIG.  13   ). 
     Important differences were observed between Eligobiotics® depending on the size of the packaged payload. Although Eligobiotics® packaging the smaller p1392 (11.615 kb) yielded almost exclusively particles containing 4 copies of the payload, small increases (up to 800 bp) in the size of the payload correlate with a shift towards packaging 3 copies. As such, Eligobiotics® produced with p779 (12.428 kb) packaged preferentially 3 copies of the payload while approximately a third of the particles contained 4 copies ( FIG.  14   ). 
     Thus, it appears that p1392 is close to an ideal size to package exclusively 4 copies of payload in Eligobiotics® particles, yielding an homogenous population. Increasing the size of the payload compared to p1392 generates more heterogeneous Eligobiotics® populations, with increasing proportions of particles containing 3 copies of payload. From this dataset, it appears that there is a lower limit for concatemer packaging close to 36 kb, as described in the literature [28]. p1085, with a size of 12.125 kb, could package 3 copies per head (36.375 kb) or 4 copies per head (48.5 kb), although the 4 copies species is preferred as seen in  FIG.  14   . Increasing the size to 12.428 kb would allow packaging of 3 copies per head (37.284 kb) and 4 copies per head (49.712 kb); in this case, 4 copies are preferred. From these two data points, the inventors inferred that the lower limit for packaging is indeed around 36 kb but with a lower efficiency. Increasing the size just by 909 bp completely shifts the packaged species to 4 copies: the limit for optimal efficiency of packaging, probably driven by a pressure signal in the capsid, lies within these two sizes. Finally, the 11.615 kb payload packages virtually only 4 copies per head (46.46 kb), as the 3-copy species is slightly below the packaging limit, even at low efficiency (34.845 kb). 
     From these data, it can also be predicted which sizes would give packaging of single and multimeric species, as shown below in Tables 2 and 3. Smaller sizes yielding single packaged species are generally preferred for several reasons, including ease of manipulation and lower probability of introducing unwanted restriction sites. Finally, sizes that allow for very efficient packaged species that are not too small (26-39 kb) or too large (50-51 kb) are also preferred in some cases as it has been shown that the amount of DNA present in the capsid may alter the packaging and stability of the particles due to intracapsid pressure [29]-[30]. Finally, sizes that are large enough to allow for production of packaged phagemids at high titer are also more particularly preferred.
