Description: Nucleic acid molecules specific for bacterial antigens and uses thereof. TECHNICAL FIELD The invention relates to novel nucleotide sequences located in a gene cluster which controls the synthesis of a bacterial polysaccharide antigen, especially an O antigen, and the use of those nucleotide sequences for the detection of bacteria which express particular polysaccharide antigens (particularly 0 antigens) and for the identification of the polysaccharide antigens (particularly 0 antigens) of those bacteria. BACKGROUND ART Enteropathogenic E , coli strains are well known causes of diarrhoea and haemorrhagic colitis in humans and can lead to potentially life threatening sequelae including haemolytic uremic syndrome and thrombotic thrombocytopaenic purpura. Some of these strains are commonly found in livestock and infection in humans is usually a consequence of consumption of contaminated meat or dairy products which have been improperly processed. The O specific polysaccharide component (the "0 antigen") of lipopolysaccharide is known to be a major virulence factor of enteropathogenic EL . coli strains. The EL . coli O antigen is highly polymorphic and 166 different forms of the antigen have been defined; Ewing, W. H. [in Edwards and Ewings "Identification of the Enterobacteriacea" Elsevier. Amsterdam (1986)] discusses 128 different 0 antigens while Lior H. (1994) extends the number to 166 [in "Classification of Escherichia coli In Escherichia coli in domestic animals and humans pp31-72. Edited by C.L. Gyles CAB International] . The genus Salmonella enterica has 46 known 0 antigen types [Popoff M.Y. et al (1992) " Antigenic formulas of the Salmonella enterica serovars" 6th revision WHO Collaborating Centre for Reference and Research on Salmonella enterica, Institut Pasteur Paris France] . An important step in determining the biosynthesis of O antigens -and therefore the mechanism of the polymorphism has been to characterise the gene clusters controlling O antigen biosynthesis. The genes specific for the synthesis of the 0 antigen are generally located in a gene cluster at map position 45 minutes on the chromosome of E . coli K-12 [Bachmann, B. J. 1990 "Linkage map of Escherichia coli K-12". Microbiol . Rev. 54: 130-197], and at the corresponding position in _________ enterica LT2 [Sanderson et al (1995) "Genetic map of Salmonella enterica typhimurium" , Edition VIII Microbiol. Rev. 59: 241-303] . In both cases the O antigen gene cluster is close to the gnd gene as is the case in other strains of E . coli and £L_ enterica [Reeves P.R. (1994) "Biosynthesis and assemby of lipopolysaccharide, 281-314. in A. Neuberger and L.L.M. van Deenen (eds) "Bacterial cell wall, new comprehensive biochemistry " vol 27 Elsevier Science Publishers] . These genes encode enzymes for the synthesis of nucleotide diphosphate sugars and for assembly of the sugars into oligosaccharide units and in general for polymerisation to O antigen. The EL . coli 0 antigen gene clusters for a wide range of EL. coli O antigens have been cloned but the 07, 09, 016 and 0111 0 antigens have been studied in more detail with only 09 and 016 having been fully characterised with regard to nucleotide sequence to date [Kido N. , Torgov V.I., Sugiyama T., Uchiya K. , Sugihara H. , Komatsu T., Kato N. & Jann K.

Of the closely related Shiαella (which really can be considered to be part of EL. coli) S . dysenteriae and S_. flexneri 0 antigens have been fully sequenced and are next to gnd. [Klena JD & Schnait an CA (1993) "Function of the rfb gene cluster and the rfe gene in the synthesis of O antigen by Shigella dysenteriae 1" Mol.

Bacteriol 176: 733-747] Inasmuch as the 0 antigen of enteropathogenic EL . coli strains and the 0 antigen of Salmonella enterica strains are major virulence factors and are highly polymorphic, there is a real need to develop highly specific, sensitive, rapid and inexpensive diagnostic assays to detect EL . coli and assays to detect £L_ enterica. There is also a rea-l need to develop diagnostic assays to identify the O antigens of EL . coli strains and assays to identify the 0 antigens of £L_ enterica strains. With regard to the detection of __________ coli these needs extend beyond EHEC (enteropathogenic haemorrhagic EL . coli) strains but this is the area of greatest need. There is interest in diagnostics for ETEC (enterotoxigenic EL . coli) etc in E. coli . The first diagnostic systems employed in this field used large panels of antisera raised against EL_ coli O antigen expressing strains or EL . enterica 0 antigen expressing strains. This technology has inherent difficulties associated with the preparation, storage and usage of the reagents, as well as the time required to achieve a meaningful diagnostic result. Nucleotide sequences derived from the O antigen gene clusters of £L_ enterica strains have been used to determine £L. enterica 0 antigens in a PCR assay [Luk, J.M.C. et al . (1993) "Selective amplification of abequose and paratose synthase genes { rfb) by polymerase chain reaction for identification of £ _ enterica major serogoups (A, B, C2, and D)", J. Clin . Microbiol . 31:2118-2123 ]. The prior complete nucleotide sequence characterisation of the entire rfb locus of serovars Typhimurium, Paratyphi A, Typhi, Muenchen, and Anatum; representing groups B, A, Dl , C2 and El respectively enabled Luk et al . to select oligonucleotide primers specific for those serogroups . Thus the approach of Luk et al . was based on aligning known nucleotide sequences corresponding to CDP-abequose and CDP-paratose synthesis genes within the 0 antigen regions of S . enterica serogroups El, Dl, A, B and C2 and exploiting the observed nucleotide sequence differences in order to identify serotype-specific oligonucleotides . In an attempt to determine the O antigen serotype of a Shiga-like toxin producing EL . coli strain, Paton, A. W. , et al . 1996 ["Molecular microbiological investigation of an outbreak of Hemolytic-Uremic Syndrome caused by dry fermented sausage contaminated with Shiga-like toxin producing -Escherichia coli". J. Clin . Microbiol . 34: 1622- 1627], used oligonucleotides derived from the wbdl ( orf6 ) region, which were believed to be specific to the EL_ coli 0111 antigen and which were derived from EL. coli 0111 sequence, in a PCR diagnostic assay. Unpublished reports indicate that the approach of Paton et al . is deficient in that the nucleotide sequences derived from wbdl may not specifically identify the 0111 antigen and in fact lead to detection of false positive results. Paton et al . disclose the detection of 5 0111 antigen isolates by PCR when in fact from only 3 of those isolates did they detect bacteria which reacted with 0111 specific antiserum. DESCRIPTION OF THE INVENTION Whilst not wanting to be held to a particular hypothesis, the present inventors now believe that the reported false positives found with the Paton et al . method are due to the fact that the nucleic acid molecules employed by Paton et al . were derived from genes which have a putative function as a sugar pathway gene, [Bastin D.A. and Reeves, P.R. (1995) Sequence and analysis of the 0 antigen gene(r£b) cluster of Escherichia coli 0111. Gene 164: 17-23] which they now believe to lack the necessary nucleotide sequence specificity to identify the EL. coli 0 antigen. The inventors now believe that many of the nucleic acid molecules derived from sugar pathway genes expressed in SL_ enterica or other enterobacteria are also likely to lack the necessary nucleotide sequence specificity to identify specific 0 antigens or specific serotypes . In this regard it is important to note that the genes for the synthesis of a polysaccharide antigen include those related to the synthesis of the sugars present in the antigen (sugar pathway genes) and those related to the manipulation of those sugars to form the polysaccharide. The present invention is predominantly concerned with the latter group of genes, particularly the assembly and transport genes such as transferase, polymerase and flippase genes. The present inventors have surprisingly found that the use of nucleic acid molecules derived from particular assembly and transport genes, particularly transferase, wzx and wzy genes, within O antigen gene clusters can improve the specificity of the detection and identification of 0 antigens. The present inventors believe that the invention is not necessarily limited to the detection of the particular O antigens which are encoded by the nucleic acid molecules exemplified herein, but has broad application for the detection of bacteria which express an 0 antigen and the identification of O antigens in general. Further because of the similarities between the gene clusters involved in the synthesis of O antigens and other polymorphic polysaccharide antigens, such as bacterial capsular antigens, the inventors believe that the methods and molecules of the present invention are also applicable to these other polysaccharide antigens. Accordingly, in one aspect the present invention relates to the identification of nucleic acid molecules which are useful for the detection and identification of specific bacterial polysaccharide antigens. The invention provides a nucleic acid molecule derived from: a gene encoding a transferase; or a gene encoding an enzyme for the transport or processing of a polysaccharide or oligosaccharide unit, including a wzx gene, wzy gene, or a gene with a similar function; the gene being involved in the synthesis of a particular bacterial polysaccharide antigen, wherein the sequence of the nucleic acid molecule is specific to the particular bacterial polysaccharide antigen. Polysaccharide antigens, such as capsular antigens of E. coli (Type I and Type II) , the Virulence capsule of __________ enterica sv Typhi and the capsules of species such as Streptococcus pneumoniae and Staphylococcus albus are encoded by genes which include nucleotide sugar pathway genes, sugar transferase genes and genes for the transport and processing of the polysaccharide or oligosaccharide unit. In some cases these are wzx or wzy but in other cases they are quite different because a different processing pathway is used. Examples of other gene clusters include the gene clusters for an extracellular polysaccharide of Streptococcus thermophilus , an exopolysaccharide of Rhizobium melilotti and the K2 capsule of Klebsiella pneumoniae . These all have genes which by experimental analysis, comparison of nucleotide sequence or predicted protein structure, can be seen to include nucleotide sugar pathway genes, sugar transferase genes and genes for oligosaccharide or polysaccharide processing. In the case of the __________ coli K-12 colanic acid capsule gene cluster [Stevenson et al (1996) "Organization of the Escherichia coli K-12 gene cluster responsible for production of the extracellular polysaccharide colanic acid". J. Bacteriol 178: 4885-4893] genes from the three classes were identified either provisionally or definitively. Colanic acid capsule is classified with the Type I capsule of EL. coli . The present inventors believe that, in general, transferase genes and genes for oligosaccharide processing will be more specific for a given capsule than the genes coding for the nucleotide sugar synthetic pathways as most sugars present in such capsules occur in the capsules of different serotypes. Thus the nucleotide sugar synthesis pathway genes could now be predicted to be common to more than one capsule type . As elaborated below the present inventors recognise that there may be polysaccharide antigen gene clusters which share transferase genes and/or genes for oligosaccharide or polysaccharide processing so that completely random selection of nucleotide sequences from within these genes may still lead to cross-reaction; an example with respect to capsular antigens is provided by the EL_ coli type II capsules for which only transferase genes are -sufficiently specific. However, the present inventors in light of their current results nonetheless consider the transferase genes or genes controlling oligosaccharide or polysaccharide processing to be superior targets for nucleotide sequence selection for the specific detection and characterisation of polysaccharide antigen types. Thus where there is similarity between particular genes, selection of nucleotide sequences from within other transferase genes or genes for oligosaccharide or polysaccharide processing from within the relevant gene cluster will still provide specificity, or alternatively the use of combinations of nucleotide sequences will provide the desired specificity. The combinations of nucleotide sequences may include nucleotide sequences derived from pathway genes together with nucleotide sequences derived from transferase, wzx or wzy genes . Thus the invention also provides a panel of nucleic acid molecules wherein the nucleic acid molecules are derived from a combination of genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes; wherein the combination of genes is specific to the synthesis of a particular bacterial polysaccharide antigen and wherein the panel of nucleic acid molecules is specific to a bacterial polysaccharide antigen. In another preferred form, the nucleic acid molecules are derived from a combination of genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, together with nucleic acid molecules derived from pathway genes . In a second aspect the present invention relates to the identification of nucleic acid molecules which are useful for the detection of bacteria which express O antigens and for the identification of the O antigens of those bacteria in diagnostic assays . The invention provides a nucleic acid molecule derived from: a gene encoding a transferase; or a gene encoding an enzyme for the transport or processing of a polysaccharide or oligosaccharide unit such as a wzx or wzy gene, the gene being involved in the synthesis of a particular bacterial 0 antigen, wherein the sequence of the nucleic acid molecule is specific to the particular bacterial 0 antigen. The nucleic acids of the invention may be variable in length. In one embodiment they are from about 10 to about 20 nucleotides in length. In one preferred embodiment, the invention provides a nucleic acid molecule derived from: a gene encoding a transferase; or a gene encoding an enzyme for the transport or processing of a polysaccharide or oligosaccharide unit including a wzx or wzy gene the gene being involved in the synthesis of an 0 antigen expressed by EL. coli , wherein the sequence of the nucleic acid molecule is specific to the 0 antigen. In one more preferred embodiment, the sequence of the nucleic acid molecule is specific to the nucleotide sequence encoding the 0111 antigen (SEQ ID N0:1). More preferably, the sequence is derived from a gene selected from the group consisting of wbdH (nucleotide position 739 to 1932 of SEQ ID NO:l), wzx (nucleotide position 8646 to 9911 of SEQ ID N0:1), wzy (nucleotide position 9901 to 10953 of SEQ ID NO:l), wbdM (nucleotide position 11821 to 12945 of SEQ ID NO:l) and fragments of those molecules of at least 10-12 nucleotides in length. Particularly preferred nucleic acid molecules are those set out in Table 5 and 5A, with respect to the above mentioned genes . In another more preferred embodiment, the sequence of the nucleic acid molecule is specific to the nucleotide sequence encoding the 0157 antigen (SEQ ID NO: 2) . More preferably the sequence is derived from a gene selected from the group consisting of wbdN (nucleotide position 79 to 861 of SEQ ID NO : 2 ) , wbdO, (nucleotide position 2011 to 2757 of SEQ ID N0:2), wbdP (nucleotide position 5257 to 6471 of SEQ ID NO : 2 ) ) , wbdR (13156 to 13821 of SEQ ID NO:2), wzx- (nucleotide position 2744 to 4135 of " SEQ ID NO: 2) and wzy (nucleotide position 858 to 2042 of SEQ ID NO: 2) . Particularly preferred nucleic acid molecules are those set out in Table 6 and 6A. The invention also provides in a further preferred embodiment a nucleic acid molecule derived from: a gene encoding a transferase; or a gene encoding an enzyme for the transport or processing of a polysaccharide or oligosaccharide unit including a wzx or wzy gene; the gene being involved in the synthesis of an 0 antigen expressed by Salmonella enterica, wherein the sequence of the nucleic acid molecule is specific to the O antigen. In one more preferred form of this embodiment, the sequence of the nucleic acid molecule is specific to the nucleotide sequence encoding the £L_ enterica C2 antigen (SEQ ID NO: 3) . More preferably the sequence of the nucleic acid molecule is derived from a gene selected from the group consisting of wbaR (nucleotide position 2352 to 3314 of SEQ ID NO : 3 ) , wbaL (nucleotide position 3361 to 3875 of SEQ ID NO : 3 ) wbaQ (nucleotide position 3977 to 5020 of SEQ ID NO : 3 ) wbaW (nucleotide position 6313 to 7323 of SEQ ID NO : 3 ) wbaZ (nucleotide position 7310 to 8467 of SEQ ID NO : 3 ) wzx (nucleotide position 1019 to 2359 of SEQ ID NO : 3 ) and wzy (nucleotide position 5114 to 6313 of SEQ ID NO : 3 ) . Particularly preferred nucleic acid molecules are those set out in Table 7. In another more preferred form of this embodiment, the sequence of the nucleic acid molecule is specific to the nucleotide sequence encoding the __________ enterica B antigen (SEQ ID NO: 4). More preferably the sequence is derived from wzx (nucleotide position 12762 to 14054 of SEQ ID NO: 4) or wbaV (nucleotide position 14059 to 15060 of SEQ ID NO: 4) . Particularly preferred nucleic acid molecules are those set out in Table 8 which are derived from wzx and wbaV genes . In a further more preferred form of this embodiment, the sequence of the nucleic acid molecule is specific to the £L . enterica D3 O antigen and is derived from the wzy gene . In yet a further preferred form of this embodiment, the sequence of the nucleic acid molecule is specific to the A_ enterica El 0 antigen and is derived from the wzx gene . While transferase genes, or genes coding for the transport or processing of a polysaccharide or oligosaccharide unit, such as a wzx or wzy gene, are superior targets for specific detection of individual 0 antigen types there may well be individual genes or parts of them within this group that can be demonstrated to be the same or closely related between different O antigen types such that cross-reactions can occur. Cross reactions should be avoided by the selection of a different target within the group or the use of multiple targets within the group. Further, it is recognised that there are cases where 0 antigen gene clusters have arisen from recombination of at least two strains such that the unique 0 antigen type is provided by a combination of gene products shared with at least two other 0 antigen types. The recognised example of this phenomenon is the £L_ enterica O antigen serotype D2 which has genes from Dl and El but none unique to D2. In these circumstances the detection of the O antigen type can still be achieved in accordance with the invention, but requires the use of a combination of nucleic acid molecules to detect a specific combination of genes that exists only in that particular O antigen gene cluster. Thus, the invention also provides a panel of nucleic acid molecules wherein the nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, wherein the panel of nucleic acid molecules is specific to a bacterial 0 antigen. Preferably the particular bacterial 0 antigen is expressed by £L . enterica. More preferably, the panel of nucleic acid molecules is specific to the D2 O antigen and is derived from the El wzy gene and the Dl wzx gene . The combinations of nucleotide sequences may include nucleotide sequences derived from pathway genes, together with nucleotide sequences derived from transferase, wzx or wzy genes . Thus, the invention also provides a panel of nucleic acid molecules, wherein the nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, and sugar pathway genes, wherein the panel of nucleic acid molecules is specific to a particular bacterial O antigen. Preferably the O antigen is expressed £L_ enterica. Further it is recognised that there may be instances where spurious hybridisation will arise through initial selection of a sequence found in many different genes but this is typically recognisable by, for instance, comparison of band sizes against controls in PCR gels, and an alternative sequence can be selected. The present inventors believe that based on the teachings of the present invention and available information concerning polysaccharide antigen gene clusters (including 0 antigen gene clusters), and through use of experimental analysis, comparison of nucleic acid sequences or predicted protein structures, nucleic acid molecules in accordance with the invention can be readily derived for any particular polysaccharide antigen of interest. Suitable bacterial strains can typically be acquired commercially from depositary institutions. As mentioned above there are currently 166 defined E. coli 0 antigens while the SL . enterica has 46 known 0 antigen types [Popoff M.Y. et al (1992) "Antigenic formulas of the Salmonella serovars" 6th revision WHO Collaborating centre for Reference and Research on Salmonella, Institut Pasteur Paris France] . Many other genera of bacteria are known to have O antigens and these include Citrobacter , Shigella, Yersinia, Plesiomonas , Vibrio and Proteus . Samples of the 166 different E. coli O antigen serotypes are available from Statens Serum Institut, Copenhagen, Denmark. The 46 £L_ enterica serotypes are available from Institute of Medical and Veterinary Science, Adelaide, Australia. In another aspect, the invention relates to a method of testing a sample for the presence of one or more bacterial polysaccharide antigens comprising contacting the sample with at least one oligonucleotide molecule capable of specifically hybridising to: (i) a gene encoding a transferase, or (ii) a gene encoding an enzyme for transport or processing of oligosaccharide or polysaccharide units, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the bacterial polysaccharide antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial polysaccharide antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules. Where a single specific oligonucleotide molecule is unavailable a combination of molecules hybridising specifically to the target region may be used. Thus the invention provides a panel of nucleic acid molecules for use in the method of testing of the invention, wherein the nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, wherein the panel of nucleic acid molecules is specific to a particular bacterial polysaccharide. The panel of nucleic acid molecules can include nucleic acid molecules derived from sugar pathway genes where necessary. In another aspect, the invention relates to a method of testing a sample for the presence of one or more bacterial polysaccharide antigens comprising contacting the sample -with at least one pair of oligonucleotide molecules, with at least one oligonucleotide molecule of the pair capable of specifically hybridising to: (i) a gene encoding a transferase, or (ii) a gene encoding an enzyme for transport or processing oligosaccharide or polysaccharide units, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the bacterial polysaccharide antigen; under conditions suitable to permit the at least one oligonucleotide molecule of the pair of molecules to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial polysaccharide antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules. The pair of oligonucleotide molecules may both hybridise to the same gene or to different genes. Only one oligonucleotide molecule of the pair need hybridise specifically to sequence specific for the particular antigen type. The other molecule can hybridise to a nonspecific region. Where the particular polysaccharide antigen gene cluster has arisen through recombination, the at least one pair of oligonucleotide molecules may be selected to be capable of hybridising to a specific combination of genes in the cluster specific to that polysaccharide antigen, or multiple pairs may be selected to provide hybridisation to the specific combination of genes. Even where all the genes in a particular cluster are unique, the method may be carried out using nucleotide molecules which recognise a combination of genes within the cluster. Thus the invention provides a panel containing pairs of nucleic acid molecules for use in the method of testing of the invention, wherein the pairs of nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, wherein the panel of nucleic acid molecules is specific to a particular bacterial polysaccharide antigen. The panel of nucleic acid molecules can include pairs of nucleic acid molecules derived from sugar pathway genes where necessary. In another aspect, the invention relates to a method of testing a sample for the presence of one or more particular bacterial 0 antigens comprising contacting the sample with at least one oligonucleotide molecule capable of specifically hybridising to: (i) a gene encoding an O antigen transferase, or (ii) a gene encoding an enzyme for transport or processing of the oligosaccharide or polysaccharide unit, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the particular 0 antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial 0 antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules . Preferably the bacteria are EL . coli or SL_ enterica. More preferably, the EL. coli express the 0157 serotype or the 0111 serotype. More preferably the S . enterica express the C2 or B serotype. Preferably, the method is a Southern blot method. More preferably, the nucleic acid molecule is labelled and hybridisation of the nucleic acid molecule is detected by autoradiography or detection of fluorescence. The inventors envisage circumstances where a single specific oligonucleotide molecule is unavailable. In these circumstances a combination of molecules hybridising specifically to the target region may be used. Thus the invention provides a panel of nucleic acid molecules for use in the method of testing of the invention, wherein the nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, wherein the panel of nucleic acid molecules is specific to a particular bacterial O antigen. Preferably the particular bacterial O antigen is expressed by £L_ enterica . The panel of nucleic acid molecules can include nucleic acid molecules derived from sugar pathway genes where necessary. In another aspect, the invention relates to a method of testing a sample for the presence of one or more particular bacterial 0 antigens comprising contacting the sample with at least one pair of oligonucleotide molecules with at least one oligonucleotide molecule of the pair being capable of specifically hybridising to: (i) a gene encoding an O antigen transferase, or (ii) a gene encoding an enzyme for transport or processing of the oligosaccharide or polysaccharide unit, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the particular 0 antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial O antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules. Preferably the bacteria are EL . coli or SL_ enterica. More preferably, the EL. coli are of the 0111 or the 0157 serotype. More preferably the £A enterica express the C2 or B serotype. Preferably, the method is a polymerase chain reaction method. More preferably the oligonucleotide molecules for use in the method of the invention are labelled. Even more preferably the hybridised oligonucleotide molecules are detected by electrophoresis. Preferred oligonucleotides for use with 0111 which provide for specific detection of 0111 are illustrated in Table 5 and 5A with respect to the genes wbdH, wzx, wzy and wbdM. Preferred oligonucleotide molecules for use with 0157 which provide for specific detection of 0157 are illustrated in Table 6 and 6A. With respect to serotypes C2 and B, suitable oligonucleotide molecules can be selected from appropriate regions described in column 3 of Tables 7 and 8. The inventors envisage rare circumstances whereby two genetically similar gene clusters encoding serologically different 0 antigens have arisen through recombination of genes or mutation so as to generate polymorphic variants . In these circumstances multiple pairs of oligonucleotides may be selected to provide hybridisation to the specific combination of genes . The invention thus provides a panel containing pairs of nucleic acid molecules for use in the method of testing of the invention, wherein the pairs of nucleic acid molecules are derived from genes encoding transferases and/or enzymes for the transport or processing of a polysaccharide or oligosaccharide unit including wzx or wzy genes, wherein the panel of nucleic acid molecules is specific to a particular bacterial 0 antigen. Preferably the particular bacterial 0 antigen is expressed by S_=. enterica. The panel of nucleic acid molecules can include pairs of nucleic acid molecules derived from sugar pathway genes where necessary. In another aspect, the invention relates to a method for testing a food derived sample for the presence of one or more particular bacterial O antigens comprising contacting the sample with at least one pair of oligonucleotide molecules with at least one oligonucleotide molecule of the pair being capable of specifically hybridising to: (i) a gene encoding an 0 antigen transferase, or (ii) a gene encoding an enzyme for transport or processing of the oligosaccharide or polysaccharide unit, including a wzx or wzy gene; wherein the gene is involved in the synthesis of the particular O antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial polysaccharide antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules . Preferably the bacteria are E . coli or S_ enterica. More preferably, the EL. coli are of the 0111 or 0157 serotype. More preferably the S . enterica are of the C2 or B serotype. Preferably, the method is a polymerase chain reaction method. More preferably the oligonucleotide molecules for use in the method of the invention are labelled. Even more preferably the hybridised oligonucleotide molecules are detected by electrophoresis . In another aspect the present invention relates to a method for testing a faecal derived sample for the presence of one or more particular bacterial O antigens comprising contacting the sample with at least one pair of oligonucleotide molecules with at least one oligonucleotide molecule of the pair being capable of specifically hybridising to: (i) a gene encoding an 0 antigen transferase, or (ii) a gene encoding an enzyme for transport or processing of the oligosaccharide or polysaccharide unit, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the particular O antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one of said genes of any bacteria expressing the particular bacterial 0 antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules.

Even more preferably the hybridised oligonucleotide molecules are detected by electrophoresis . In another aspect, the present invention relates to a method for testing a sample derived from a patient for the presence of one or more particular bacterial 0 antigens comprising contacting the sample with at least one pair of oligonucleotide molecules with at least one oligonucleotide molecule of the pair being capable of specifically hybridising to: (i) a gene encoding an O antigen transferase, or (ii) a gene encoding an enzyme for transport or processing of the oligosaccharide or polysaccharide unit, including a wzx or wzy gene; wherein said gene is involved in the synthesis of the particular O antigen; under conditions suitable to permit the at least one oligonucleotide molecule to specifically hybridise to at least one such gene of any bacteria expressing the particular bacterial 0 antigen present in the sample and detecting any specifically hybridised oligonucleotide molecules .

Preferably, the method is a polymerase chain reaction method. More preferably the oligonucleotide molecules for use in the method of the invention are labelled. Even more preferably the hybridised oligonucleotide molecules are detected by electrophoresis. In the above described methods it will be understood that where pairs of oligonucleotides are used one of the oligonucleotide sequences may hybridise to a sequence that is not from a transferase, wzx or wzy gene. Further where both hybridise to one of these gene products they may hybridise to the same or a different one of these genes. In addition it will be understood that where cross reactivity is an issue a combination of oligonucleotides may be chosen to detect a combination of genes to provide specificity. The invention further relates to a diagnostic kit which can be used for the detection of bacteria which express bacterial polysaccharide antigens and the identification of the bacterial polysaccharide type of those bacteria. Thus in a further aspect, the invention relates to a kit comprising a first vial containing a first nucleic acid molecule capable of specifically hybridising to: (i) a gene encoding a transferase, or (ii) a gene encoding an enzyme for transport or processing oligosaccharide or polysaccharide, including a wzx or wzy gene, wherein the said gene is involved in the synthesis of a bacterial polysaccharide. The kit may also provide in the same or a separate vial a second specific nucleic acid capable of specifically hybridising to : (i) a gene encoding a transferase, or (ii) a gene encoding an enzyme for transport or processing oligosaccharide or polysaccharide, including a wzx or wzy gene, wherein the said gene is involved in the synthesis of a bacterial polysaccharide, wherein the sequence of the second nucleic acid molecule is different from the sequence of the first nucleic acid molecule . In a further aspect the invention relates to a kit comprising a first vial containing a first nucleic acid molecule capable of specifically hybridising to: (i) a gene encoding a transferase, or (ii) a gene encoding an enzyme for transport or processing oligosaccharide or polysaccharide including wzx or wzy, wherein the said gene is involved in the synthesis of a bacterial O antigen. The kit may also provide in the same or a separate vial a second specific nucleic acid capable of specifically hybridising to: (i) a gene encoding a transferase , or (ii) a gene encoding an enzyme for transport or processing oligosaccharide or polysaccharide including wzx or wzy, wherein the said gene is involved in the synthesis of 0 antigen, wherein the sequence of the second nucleic acid molecule is different from the sequence of the first nucleic acid molecule. Preferably the first and second nucleic acid sequences are derived from £L_ coli or the first and second nucleic acid sequences are derived from S . enterica. The present inventors provide full length sequence of the 0157 gene cluster for the first time and recognise that from this sequence of this previously uncloned full gene cluster appropriate recombinant molecules can be generated and inserted for expression to provide expressed 0157 antigens useful in applications such as vaccines . DEFINITIONS The phrase, "a nucleic acid molecule derived from a gene" means that the nucleic acid molecule has a nucleotide sequence which is either identical or substantially similar to all or part of the identified gene. Thus a nucleic acid molecule derived from a gene can be a molecule which is isolated from the identified gene by physical separation from that gene, or a molecule which is artificially synthesised and has a nucleotide sequence which is either identical to or substantially similar to all or part of the identified gene. While some workers consider only the DNA strand with the same sequence as the mRNA transcribed from the gene, here either strand is intended. Transferase genes are regions of nucleic acid which have a nucleotide sequence which encodes gene products that transfer monomeric sugar units. Flippase or wzx genes are regions of nucleic acid which have a nucleotide sequence which encodes a gene product that flips oligosaccharide repeat units generally composed of three to six monomeric sugar units to the external surface of the membrane. Polymerase or wzy genes are regions of nucleic acid which have a nucleotide sequence which encodes gene products that polymerise repeating oligosaccharide units generally composed of 3-6 monomeric sugar units. The nucleotide sequences provided in this specification are described in the sequence listing as anti-sense sequences. This term is used in the same manner as it is used in Glossary of Biochemistry and Molecular Biology Revised Edition, David M. Glick, 1997 Portland Press Ltd. , London on page 11 where the term is described as referring to one of the two strands of double-stranded DNA usually that which has the same sequence as the mRNA. We use it to describe this strand which has the same sequence as the mRNA.

BEST METHOD FOR CARRYING OUT THE INVENTION Materials and Methods-part 1 The experimental procedures for the isolation and characterisation of the EL . coli 0111 0 antigen gene cluster (position 3,021-9,981) are according to Bastin D.A. , et al . 1991 "Molecular cloning and expression in Escherichia coli K-12 of the rfb gene cluster determining the 0 antigen of an L . coli 0111 strain". Mol . Microbiol . 5:9 2223-2231 and Bastin D.A. and Reeves, P.R. 1995 "Sequence and analysis of the O antigen gene ( rfb) cluster of Escherichia coli 0111". Gene 164: 17-23. A. Bacterial strains and growth media Bacteria were grown in Luria broth supplemented as required. B . Cosmids and phage Cosmrds in the host strain x2819 were repackaged in vivo . Cells were grown in 250mL flasks containing 30mL of culture, with moderate shaking at 30°C to an optical density of 0.3 at 580 nm. The defective lambda prophage was induced by heating in a water bath at 45°C for 15min followed by an incubation at 37°C with vigorous shaking for 2hr. Cells were then lysed by the addition of 0.3mL chloroform and shaking for a further lOmin. Cell debris were removed from lmL of lysate by a 5min spin in a microcentrifuge, and the supernatant removed to a fresh microfuge tube. One drop of chloroform was added then shaken vigorously through the tube contents. C. DNA preparation Chromosomal DNA was prepared from bacteria grown overnight at 37°C in a volume of 30mL of Luria broth. After harvesting by centrifugation, cells were washed and resuspended in lOmL of 50mMTris-HCl pH 8.0. EDTA was added and the mixture incubated for 20min. Then lysozyme was added and incubation continued for a further lOmin. Proteinase K, SDS, and ribonuclease were then added and the mixture incubated for up to 2hr for lysis to occur. All incubations were at 37°C. The mixture was then heated to 65°C and extracted once with 8mL of phenol at the same temperature. The mixture was extracted once with 5mL of phenol/chloroform/iso-amyl alcohol at 4°C. Residual phenol was removed by two ether extractions . DNA was precipitated with 2 vols . of ethanol at 4°C, spooled and washed in 70% ethanol, resuspended in l-2mL of TE and dialysed. Plasmid and cosmid DNA was prepared by a modification of the Birnboim and Doly method [Birnboim, H. C. And Doly, J. (1979) A rapid alkaline extraction procedure for screening recombinant plasmid DNA Nucl . Acid Res . 7:1513-1523. The volume of culture was lOmL and the lysate was extracted with phenol/chloroform/iso-amyl alcohol before precipitation with isopropanol . Plasmid DNA to be used as vector was isolated on a continuous caesium chioride gradient- following alkaline lysis of cells grown in 1L of culture. D. Enzymes and buffers. Restriction endonucleases and DNA T4 ligase were purchased from Boehringer Mannheim (Castle Hill, NSW, Australia)or Pharmacia LKB (Melbourne, VIC Australia). Restriction enzymes were used in the recommended commercial buffer. E. Construction of a gene bank. Individual aliquots of M92 chromosomal DNA (strain Stoke W, from Statens Serum Institut, 5 Artillerivej , 2300 Copenhagen S, Denmark) were partially digested with 0.2U Sau3Al for l-15mins . Aliquots giving the greatest proportion of fragments in the size range of approximately 40-50kb were selected and ligated to vector pPR691 previously digested with Ba ϋl and PvuII. Ligation mixtures were packaged in vi tro with packaging extract. The host strain for transduction was x2819 and recombinants were selected with kanamycin. F. Serological procedures. Colonies were screened for the presence of the 0111 antigen by immunoblotting . Colonies were grown overnight, up to 100 per plate then transferred to nitrocellulose discs and lysed with 0.5N HC1. Tween 20 was added to TBS at 0.05% final concentration for blocking, incubating and washing steps. Primary antibody was EL. coli O group 111 antiserum, diluted 1:800. The secondary antibody was goat anti-rabbit IgG labelled with horseradish peroxidase diluted 1:5000. The staining substrate was 4-chloro-l- napthol . Slide agglutination was performed according to the standard procedure. G. Recombinant DNA methods. Restriction mapping was based on a combination of standard methods including single and double digests and sub-cloning. Deletion derivatives of entire cosmids were produced as follows: aliquots of 1.8μg of cosmid DNA were digested in a volume of 20μl with 0.25U of restriction enzyme for 5-80min. One half of each aliquot was used to check the degree of digestion on an agarose gel . The sample which appeared to give a representative range of fragments was ligated at 4°C overnight and transformed by the CaCl 2 method into JM109. Selected plasmids were transformed into sφl74 by the same method. P4657 was transformed with pPRl244 by electroporation . H. DNA hybridisation Probe DNA was extracted from agarose gels by electroelution and was nick-translated using [α-32P] -dCTP . Chromosomal or plasmid DNA was electrophoresed in 0.8% agarose and transferred to a nitrocellulose membrane. The hybridisation and pre-hybridisation buffers contained either 30% or 50% formamide for low and high stringency probing respectively. Incubation temperatures were 42°C and 37°C for pre-hybridisation and hybridisation respectively. Low stringency washing of filters consisted of 3 x 20min washes in 2 x SSC and 0.1% SDS. High- stringency washing consisted of 3 x 5min washes in 2 x SSC and 0.1% SDS at room temperature, a lhr wash in 1 x SSC and 0.1% SDS at 58°C and 15min wash in 0.1 x SSC and 0.1% SDS at 58°C. I. Nucleotide sequencing of EL . coli 0111 0 antigen gene cluster (position 3,021-9,981) Nucleotide sequencing was performed using an ABI 373 automated sequencer (CA, USA) . The region between map positions 3.30 and 7.90 was sequenced using uni-directional exonuclease III digestion of deletion families made in PT7T3190 from clones pPRl270 and pPR1272. Gaps were filled largely by cloning of selected fragments into M13mpl8 or M13mpl9. The region from map positions 7.90-10.2 was sequenced from restriction fragments in M13mpl8 or Ml3mpl9. Remaining gaps in both the regions were filled by priming from synthetic oligonucleotides complementary to determined positions along the sequence, using a single stranded DNA template in Ml3 or phagemid. The oligonucleotides were designed after analysing the adjacent sequence. All sequencing was performed by the chain termination method. Sequences were aligned using SAP [Staden, R. , 1982 "Automation of the computer handling of gel reading data produced by the shotgun method of DNA sequencing". Nuc . Acid Res . 10: 4731-4751; Staden, R. , 1986 "The current status and portability of our sequence handling software". Nuc . Acid Res . 14: 217-231]. The program NIP [Staden, R. 1982 "An interactive graphics program for comparing and aligning nucleic acid and amino acid sequence". Nuc . Acid Res . 10: 2951-2961] was used to find open reading frames and translate them into proteins . J. Isolation of clones carrying EL. coli 0111 0 antigen gene cluster The EL . coli 0 antigen gene cluster was isolated according to the method of Bastin D.A. , et al . [1991 "Molecular cloning and expression in Escherichia coli K-12 of the rfb gene cluster determining the 0 antigen of an E. coli 0111 strain". Mol . Microbiol . 5(9), 2223-2231]. Cosmid gene banks of M92 chromosomal DNA were established in the in vivo packaging strain x2819. From the genomic bank, 3.3 x 10 3 colonies were screened with EA coli 0111 antiserum using an immuno-blotting procedure: 5 colonies (pPR1054, pPRl055, pPRl056, pPRl058 and pPRl287) were positive. The cosmids from these strains were packaged in vivo into lambda particles and transduced into the EL_ coli deletion mutant Sφl74 which lacks all 0 antigen genes. In this host strain, all plasmids gave positive agglutination with 0111 antiserum. An Eco Rl restriction map of the 5 independent cosmids showed that they have a region of approximately 11.5 kb in common (Figure 1) . Cosmid pPR1058 included sufficient flanking DNA to identify several chromosomal markers linked to 0 antigen gene cluster and was selected for analysis of the O antigen gene cluster region. K. Restriction mapping of cosmid pPRl058 Cosmid pPR1058 was mapped in two stages. A preliminary map was constxucted first, and then the region between map positions 0.00 and 23.10 was mapped in detail, since it was shown to be sufficient for 0111 antigen expression. Restriction sites for both stages are shown in Figure 2. The region common to the five cosmid clones was between map positions 1.35 and 12.95 of pPRl058. To locate the O antigen gene cluster within pPRl058, PPR1058 cosmid was probed with DNA probes covering O antigen gene cluster flanking regions from _________ enterica LT2 and EL coli K-12. Capsular polysaccharide ( cps) genes lie upstream of 0 antigen gene cluster while the gluconate dehydrogenase ( gnd) gene and the histidine (his) operon are downstream, the latter being further from the O antigen gene cluster. The probes used were pPR472 (3.35kb), carrying the gnd gene of LT2 , pPR685 (5.3kb) carrying two genes of the cps cluster, cpsB and cpsG of LT2 , and K350 (16.5kb) carrying all of the his operon of K-12. Probes hybridised as follows: pPR472 hybridised to 1.55kb and 3.5 kb (including 2.7 kb of vector) fragments of Pstl and Hindlll double digests of pPRl246 (a Hindlll /EcoRl subclone derived from pPR1058, Figure 2), which could be located at map positions 12.95-15.1; pPR685 hybridised to a 4.4 kb EcoRl fragment of pPR1058 (including 1.3 kb of vector) located at map position 0.00- 3.05; and K350 hybridised with a 32kb EcoRl fragment of pPRl058 (including 4. Okb of vector), located at map position 17.30-45.90. Subclones containing the presumed gnd region complemented a gnd ' edd ' strain GB23152. On gluconate bromothymol blue plates, pPRl244 and pPRl292 in this host strain gave the green colonies expected of a gnd * edd ~ genotype . The his * phenotype was restored by plasmid pPR1058 in the his deletion strain Sφl74 on minimal medium plates, showing that the plasmid carries the entire his operon. It is likely that the O antigen gene cluster region lies between gnd and cps , as in other E. coli and S . enterica strains, and hence between the approximate map positions 3.05 and 12.95. To confirm this, deletion derivatives of pPR1058 were made as follows: first, PPR1058 was partially digested with HindiII and self ligated. Transformants were selected for kanamycin resistance and screened for expression of 0111 antigen. Two colonies gave a positive reaction. EcoRl digestion showed that the two colonies hosted identical plasmids, one of which was designated pPRl230, with an insert which extended from map positions 0.00 to 23.10. Second pPR1058 was digested with Sail and partially digested with Xhol and the compatible ends were re-ligated. Transformants were selected with kanamycin and screened for 0111 antigen expression. Plasmid DNA of 8 positively reacting clones was checked using EcoRl and Xhol digestion and appeared to be identical. The cosmid of one was designated pPR1231. The insert of pPR1231 contained the DNA region between map positions 0.00 and 15.10. Third, pPRl231 was partially digested with Xhol, self-ligated, and transformants selected on spectinomycin/ streptomycin plates. Clones were screened for kanamycin sensitivity and of 10 selected, all had the DNA region from the Xhol site in the vector to the Xhol site at position 4.00 deleted. These clones did not express the 0111 antigen, showing that the Xhol site at position 4.00 is within the O antigen gene cluster. One clone was selected and named pPR1288. Plasmids pPRl230, pPRl231, and pPR1288 are shown in Figure 2. L. Analysis of the E. coli 0111 0 antigen gene cluster (position 3,021-9,981) nucleotide sequence data Bastin and Reeves [1995 "Sequence and analysis of the 0 antigen gene ( rfb) cluster of Escherichia coli 0111". Gene 164: 17-23] partially characterised the EL. coli 0111 O antigen gene cluster by sequencing a fragment from map position 3,021-9,981. Figure 3 shows the gene organisation of position 3,021-9,981 of EL_ coli 0111 O antigen gene cluster. orf3 and orf6 have high level amino acid identity with wcaH and wcaG (46.3% and 37.2% respectively) , and are likely to be similar in function to sugar biosynthetic pathway genes in the _____ coli K-12 colanic gene cluster. orf4 and orf5 show high levels of amino acid homology to manC and manB genes respectively. orfl shows high level homology with rfbH which is an abequose pathway gene. orf8 encodes a protein with 12 transmembrane segments and has similarity in secondary structure to other wzx genes and is likely therefore to be the 0 antigen flippase gene. Materials and Methods-part 2 A. Nucleotide sequencing of 1 to 3,020 and 9,982 to 14,516 of the EL . coli 0111 O antigen gene cluster The sub clones which contained novel nucleotide sequences, pPR1231 (map position 0 and 1,510), pPR1237 (map position -300 to 2,744), pPRl239 (map position 2,744 to 4,168), pPR1245 (map position 9,736 to 12,007) and PPR1246 (map position 12,007 to 15,300) (Figure 2), were characterised as follows: the distal ends of the inserts of pPR1237, pPR1239 and pPR1245 were sequenced using the M13 forward and reverse primers located in the vector. PCR walking was carried out to sequence further into each insert using primers based on the sequence data and the primers were tagged with M13 forward or reverse primer sequences for sequencing. This PCR walking procedure was repeated until the entire insert was sequenced. pPRl246 was characterised from position 12,007 to 14,516. The DNA of these sub clones was sequenced in both directions . The sequencing reactions were performed using the dideoxy termination method and thermocycling and reaction products were analysed using fluorescent dye and an ABI automated sequencer (CA, USA) . B. Analysis of the EL . coli 0111 0 antigen gene cluster (positions 1 to 3,020 and 9,982 to 14,516 of SEQ ID N0:1) nucleotide sequence data The gene organisation of regions of EL. coli 0111 O antigen gene cluster which were not characterised by Bastin and Reeves [1995 "Sequence and analysis of the 0 antigen gene (rfb) cluster of Escherichia coli 0111." Gene 164: 17-23] , (positions 1 to 3,020 and 9,982 to 14,516) is shown in Figure 3. There are two open reading frames in region 1. Four open reading frames are predicted in region 2. The position of each gene is listed in Table 5. The deduced amino acid sequence of orfl ( wbdH) shares about 64% similarity with that of the rfp gene of Shigella dysenteriae . Rfp and WbdH have very similar hydrophobicity plots and both have a very convincing predicted transmembrane segment in a corresponding position. rfp is a galactosyl transferase involved in the synthesis of LPS core, thus wbdH is likely to be a galactosyl transferase gene. orf2 has 85.7% identity at amino acid level to the gmd gene identified in the _____ coli K-12 colanic acid gene cluster and is likely to be a gmd gene. orf9 encodes a protein with 10 predicted transmembrane segments and a large cytoplasmic loop. This inner membrane topology is a characteristic feature of all known 0 antigen polymerases thus it is likely that orf9 encodes an 0 antigen polymerase gene, wzy. orfl O (wbdL) has a deduced amino acid sequence with low homology with Lsi2 of Neisseria αonorrhoeae . Lsi2 is responsible for adding GlcNAc to galactose in the synthesis of lipooligosaccharide . Thus it is likely that wbdL is either a colitose or glucose transferase gene. orfll ( wbdM) shares high level nucleotide and amino acid similarity with TrsE of Yersinia enterocholi tica . TrsE is a putative sugar transferase thus it is likely that wbdM encodes the colitose or glucose transferase. In summary three putative transferase genes and an 0 antigen polymerase gene were identified at map position 1 to 3,020 and 9,982 to 14,516 of E ^ coli 0111 0 antigen gene cluster. A search of GenBank has shown that there are no genes with significant similarity at the nucleotide sequence level for two of the three putative transferase genes or the polymerase gene. SEQ ID N0:1 and Figure 7 provide the nucleotide sequence of the 0111 antigen gene cluster. Materials and Methods-part 3 A. PCR amplification of 0157 antigen gene cluster from an EL . coli 0157 :H7 strain (Strain C664-1992, from Statens Serum Institut, 5 Artillerivej , 2300, Copenhagen S, Denmark) E. coli 0157 0 antigen gene cluster was amplified by using long PCR [Cheng et al . 1994, Effective amplification of long targets from cloned inserts and human and genomic DNA" P.N.A.S. USA 91: 5695-569] with one primer (primer #412: att ggt age tgt aag cca agg gcg gta gcg t) based on the JumpStart sequence usually found in the promoter region of 0 antigen gene clusters [Hobbs, et al . 1994 "The JumpStart sequence: a 39 bp element common to several polysaccharide gene dusted" Mol. Microbiol. 12: 855-856], and another primer #482 (cac tgc cat ace gac gac gec gat ctg ttg ctt gg) based on the gnd gene usually found downstream of the 0 antigen gene cluster. Long PCR was carried out using the Expand Long Template PCR System from Boehringer Mannheim (Castle Hill NSW Australia) , and products, 14 kb in length, from several reactions were combined and purified using the Promega Wizard PCR preps DNA purification System (Madison WI USA) . The PCR product was then extracted with phenol and twice with ether, precipitated with 70% ethanol, and resuspended in 40μL of water. B. Construction of a random DNase I bank: Two aliquots containing about 150ng of DNA each were subjected to DNase I digestion using the Novagen DNase I Shotgun Cleavage (Madison WI USA) with a modified protocol as described. Each aliquot was diluted into 45μl of 0.05M Tris -HC1 (pH7.5), 0.05mg/mL BSA and lOmM MnCl 2 . 5μL of 1:3000 or 1:4500 dilution of DNasel (Novagen) (Madison WI USA) in the same buffer was added into each tube respectively and lOμl of stop buffer (lOOmM EDTA) , 30% glycerol, 0.5% Orange G, 0.075% xylene and cyanol (Novagen) (Madison WI USA) was added after incubation at 15°C for 5 min. The DNA from the two DNasel reaction tubes were then combined and fractionated on a 0.8% LMT agarose gel, and the gel segment with DNA of about lkb in size (about 1.5mL agarose) was excised. DNA was extracted from agarose using Promega Wizard PCR Preps DNA Purification (Madison WI USA) and resuspended in 200 μL water, before being extracted with phenol and twice with ether, and precipitated. The DNA was then resuspended in 17.25 μL water and subjected to T4 DNA polymerase repair and single dA tailing using the Novagen Single dA Tailing Kit (Madison WI USA) . The reaction product (85μl containing about 8ng DNA) was then extracted with chloroform: isoamyl alcohol (24:1) once and ligated to 3x 10 ~3 p ol pGEM-T (Promega) (Madison WI USA) in a total volume of 100μL. Ligation was carried out overnight at 4°C and the ligated DNA was precipitated and resuspended in 20μL water before being electroporated into EL. coli strain JM109 and plated out on BCIG-IPTG plates to give a bank. C. Sequencing DNA templates from clones of the bank were prepared for sequencing using the 96-well format plasmid DNA miniprep kit from Advanced Genetic Technologies Corp (Gaithersburg MD USA) The inserts of these clones were sequenced from one or both ends using the standard M13 sequencing primer sites located in the pGEM-T vector. Sequencing was carried out on an ABI377 automated sequencer (CA USA) as described above, after carrying out the sequencing reaction on an ABI Catalyst (CA USA) . Sequence gaps and areas of inadequate coverage were PCR amplified directly from 0157 chromosomal DNA using primers based on the already obtained sequencing data and sequenced using the standard M13 sequencing primer sites attached to the PCR primers . D. Analysis of the _______ coli 0157 0 antigen gene cluster nucleotide sequence data Sequence data were processed and analysed using the Staden programs [Staden, R., 1982 "Automation of the computer handling of gel reading data produced by the shotgun method' of DNA sequencing." Nuc . Acid Res . 10: 4731-4751; Staden, R. , 1986 "The current status and portability of our sequence handling software" . Nuc . Acid Res . 14: 217-231; Staden, R. 1982 "An interactive graphics program for comparing and aligning nucleic acid and amino acid sequence". Nuc . Acid Res . 10: 2951-2961]. Figure 4 shows the structure of EL . coli 0157 0 antigen gene cluster. Twelve open reading frames were predicted from the sequence data, and the nucleotide and amino acid sequences of all these genes were then used to search the GenBank database for indication of possible function and specificity of these genes. The position of each gene is listed in Table 6. The nucleotide sequence is presented in SEQ ID NO : 2 and Figure 8. orfs 10 and 11 showed high level identity to manC and manB and were named manC and manB respectively . orfl showed 89% identity (at amino acid level) to the gmd gene of the EL. coli colanic acid capsule gene cluster (Stevenson G., K. et al . 1996 "Organisation of the Escherichia coli K-12 gene cluster responsible for production of the extracellular polysaccharide colanic acid".J. Bacteriol. 178:4885-4893) and was named gmd. orf8 showed 79% and 69% identity (at amino acid level) respectively to wcaG of the EL . coli colanic acid capsule gene cluster and to wbcJ ( or f 14 . 8) gene of the Yersinia enterocolitica 08 O antigen gene cluster (Zhang, L. et al . 1997 "Molecular and chemical characterization of the lipopolysaccharide O-antigen and its role in the virulence of Y ^ . enterocolitica serotype 08".Mol. Microbiol. 23:63- 76) . Colanic acid and the Yersinia 08 0 antigen both contain fucose as does the 0157 0 antigen. There are two enzymatic steps required for GDP-L-fucose synthesis from GDP-4-keto-6-deoxy-D-mannose, the product of the gmd gene product. However, it has been shown recently (Tonetti, M et al . 1996 Synthesis of GDP-L-fucose by the human FX protein J. Biol. Chem. 271:27274-27279) that the human FX protein has "significant homology" with the wcaG gene (referred to as Yefb in that paper) , and that the FX protein carries out both reactions to convert GDP-4-keto- 6-deoxy-D-mannose to GDP-L-fucose. We believe that this makes a very strong case for orf8 carrying out these two steps and propose to name the gene fcl . In support of the one enzyme carrying out both functions is the observation that there are no genes other than manB, manC, gmd and fcl with similar levels of similarity between the three bacterial gene clusters for fucose containing structures. orf5 is very similar to wbeE (rfbE) of Vibrio cholerae 01, which is thought to be the perosamine synthetase, which converts GDP-4-keto-6-deoxy-D-mannose to GDP-perosa ine (Stroeher, U.H et al . 1995 "A putative pathway for perosamine biosynthesis is the first function encoded within the rfb region of Vibrio cholerae " 01. Gene 166: 33-42) . _____ cholerae 01 and _____ coli 0157 0 antigens contain perosamine and N-acetyl-perosamine respectively. The _____ cholerae 01 manA, manB, gmd and wbeE genes are the only genes of the _7__ cholerae 01 gene cluster with significant similarity to genes of the EL. coli 0157 gene cluster and we believe that our observations both confirm the prediction made for the function of wbe of V. cholerae. and show that orf5 of the 0157 gene cluster encodes GDP-perosamine synthetase. orf5 is therefore named per. orf5 plus about lOObp of the upstream region (postion 4022-5308) was previously sequenced by Bilge, S.S. et al . [1996 "Role of the Escherichia coli 0157-H7 0 side chain in adherence and analysis of an rfb locus" . Infect . Immun. 64:4795-4801]. orfl2 shows high level similarity to the conserved region of about 50 amino acids of various members of an acetyltransferase family (Lin, W. , et al . 1994 "Sequence analysis and molecular characterisation of genes required for the biosynthesis of type 1 capsular polysaccharide in Staphylococcus aureus". J. Bateriol . 176: 7005-7016) and we believe it is the N-acetyltransferase to convert GDP- perosamine to GDP-perNAc . orfl2 has been named wbdR . The genes manB, manC, gmd, fcl , per and wbdR account for all of " the expected biosynthetic pathway genes of the 0157 gene cluster. The remaining biosynthetic step(s) required are for synthesis of UDP-GalNAc from UDP-Glc . It has been proposed (Zhang, L., et al . 1997 "Molecular and chemical characterisation of the lipopolysaccharide 0-antigen and its role in the virulence of Yersinia enterocolitica serotype 08".Mol. Microbiol. 23:63-76) that in Yersinia enterocolitica UDP-GalNAc is synthesised from UDP-GlcNAc by a homologue of galactose epimerase (GalE) , for which there is a galE like gene in the Yersinia enterocolitica 08 gene cluster. In the case of 0157 there is no galE homologue in the gene cluster and it is not clear how UDP- GalNAc is synthesised. It is possible that the galactose epimerase encoded by the galE gene in the gal operon, can carry out conversion of UDP-GlcNAc to UDP-GalNAc in addition to conversion of UDP-Glc to UDP-Gal . There do not appear to be any gene(s) responsible for UDP-GalNAc synthesis in the 0157 gene cluster. orf4 shows similarity to many wzx genes and is named wzx and orf2 which shows similarity of secondary structure in the predicted protein to other wzy genes and is for that reason named wzy. The orfl , orf3 and orfβ gene products all have characteristics of transferases, and have been named wbdN, wbdO and jbdP respectively. The 0157 0 antigen has 4 sugars and 4 transferases are expected. The first transferase to act would put a sugar phosphate onto undecaprenol phosphate. The two transferases known to perform this function, WbaP (RfbP) and WecA (Rfe) transfer galactose phosphate and N-acetyl-glucosamine phosphate respectively to undecaprenol phosphate. Neither of these sugars is present in the 0157 structure. Further, none of the presumptive transferases in the 0157 gene cluster has the transmembrane segments found in WecA and WbaP which transfer a sugar phosphate to undecaprenol phosphate and expected for any protein which transferred a sugar to undecaprenol phosphate which is embedded within the membrane. The WecA gene which transfers GlcNAc-P to undecaprenol phosphate is located in the Enterobactereal Common Antigen (ECA) gene cluster and it functions in ECA synthesis in most and perhaps all ________ coli strains, and also in 0 antigen synthesis for those strains which have GlcNAc as the first sugar in the O unit. It appears that WecA acts as the transferase for addition of GalNAc-1-P to undecaprenol phosphate for the Yersinia enterocolitica 08 O antigen [Zhang et al.1997 "Molecular and chemical characterisation of the lipopolysaccharide O antigen and its role in the virulence of Yersinia enterocolitica serotype 08" Mol. Microbiol. 23: 63-76.] and perhaps does so here as the 0157 structure includes GalNAc . WecA has also been reported to add Glucose-1-P phosphate to undecaprenol phosphate in EL_ coli 08 and 09 strains, and an alternative possibility for transfer of the first sugar to undecaprenol phosphate is WecA mediated transfer of glucose, as there is a glucose residue in the 0157 0 antigen. In either case the requisite number of transferase genes are present if GalNAc or Glc is transferred by WecA and the side chain Glc is transferred by a transferase outside of the 0 antigen gene cluster. orf9 shows high level similarity (44% identity at amino acid level, same length) with wcaH gene of the E. coli colanic acid capsule gene cluster. The function of this gene is unknown, and we give orf9 the name wbdQ. The DNA between manB and wdbR has strong sequence similarity to one of the H-repeat units of EL. coli K12. Both of the inverted repeat sequences flanking this region are still recognisable, each with two of the 11 bases being changed. The H-repeat associated protein encoding gene located within this region has a 267 base deletion and mutations in various positions. It seems that the H- repeat unit has been associated with this gene cluster for a long period of time since it translocated to the gene cluster, perhaps playing a role in assembly of the gene cluster as ~ has been proposed in other cases. Materials and Methods - part 4 To test our hypothesis that 0 antigen genes for transferases and the wzx, wzy genes were more specific than pathway genes for diagnostic PCR, we first carried out PCR using primers for all the EL . coli 016 0 antigen genes (Table 4) . The PCR was then carried out using PCR primers for EL . coli 0111 transferase, wzx and wzy genes (Table 5, 5A) . PCR was also carried out using PCR primers for the EL. coli 0157 transferase, wzx and wzy genes (Table 6, 6A) . Chromosomal DNA from the 166 serotypes of EL. coli available from Statens Serum Institut, 5 Artillerivej , 2300 Copenhagen Denmark was isolated using the Promega Genomic (Madison WI USA) isolation kit. Note that 164 of the serogroups are described by Ewing W. H. : Edwards and Ewings "Identification of the Enterobacteriacea" Elsevier, Amsterdam 1986 and that they are numbered 1-171 with numbers 31, 47, 67, 72, 93, 94 and 122 no longer valid. Of the two serogroup 19 strains we used 19ab strain F8188- 41. Lior H. 1994 ["Classification of Eschericia coli In Eschericia coli in domestic animals and humans pp 31-72. Edited by CL. Gyles CAB international] adds two more numbered 172 and 173 to give the 166 serogroups used. Pools containing 5 to 8 samples of DNA per pool were made . Pool numbers 1 to 19 (Table 1) were used in the E. coli 0111 and 0157 assay. Pool numbers 20 to 28 were also used in the 0111 assay, and pool numbers 22 to 24 contained E. coli 0111 DNA and were used as positive controls (Table 2) . Pool numbers 29 to 42 were also used in the 0157 assay, and pool numbers 31 to 36 contained E. coli 0157 DNA, and were used as positive controls (Table 3) . Pool numbers 2 to 20, 30, 43 and 44 were used in the EL . coli 016 assay (Tables 1 to 3) . Pool number 44 contained DNA of EL. coli K-12 strains C600 and WG1 and was used as a positive control as between them they have all of the _____ coli K-12 016 O antigen genes. PCR reactions were carried out under the following conditions: denaturing 94°C/30"; annealing, temperature varies (refer to Tables 4 to 8)/30"; extension, 72°C/1'; 30 cycles. PCR reaction was carried out in an volume of 25μL for each pool. After the PCR reaction, 10μL PCR product from each pool was run on an agarose gel to check for amplified DNA. Each _____ coli and SA enterica chromosomal DNA sample was checked by gel electrophoresis for the presence of chromosomal DNA and by PCR amplification of the EL_ coli or S. enterica mdh gene using oligonucleotides based on E . coli K-12 or Salmonella enterica LT2 [Boyd et al . (1994) "Molecular genetic basis of allelic polymorphism in malate degydrogenase (mdh) in natural populations of Escherichia coli and Salmonella enterica" Proc . Nat. Acad. Sci. USA. 91:1280-1284.] Chromosomal DNA samples from other bacteria were only checked by gel electrophoresis of chro osom 1 DNA. A. Primers based on EL . coli 016 O antigen gene cluster sequence . The O antigen gene cluster of EL. coli 016 was the only typical EL . coli 0 antigen gene cluster that had been fully sequenced prior to that of 0111, and we chose it for testing our hypothesis. One pair of primers for each gene was tested against pools 2 to 20, 30 and 43 of EL. coli chromosomal DNA. The primers, annealing temperatures and functional information for each gene are listed in Table 4. For the five pathway genes, there were 17/21, 13/21, 0/21, 0/21, 0/21 positive pools for rmlB, rmlD, rmlA, rmlC and glf respectively (Table 4) . For the wzx, wzy and three transferase genes there were no positives amongst the 21 pools of EL . coli chromosomal DNA tested (Table 4) . In each case the #44 pool gave a positive result. B. Primers based on the EL . coli 0111 O antigen gene clsuter sequence. One to four pairs of primers for each of the transferase, wzx and wzy genes of 0111 were tested against the pools 1 to 21 of EL . coli chromosomal DNA (Table 5) . For wbdH, four pairs of primers, which bind to various regions of this gene, were tested and found to be specific for 0111 as there was no amplified DNA of the correct size in any of those 21 pools of ______ coli chromosomal DNA tested. Three pairs of primers for wbdM were tested, and they are all specific although primers #985/#986 produced a band of the wrong size from one pool. Three pairs of primers for wzx were tested and they all were specific. Two pairs of primers were tested for wzy, both are specific although #980/#983 gave a band of the wrong size in all pools. One pair of primers for wbdL was tested and found unspecific and therefore no further test was carried out. Thus, wzx, wzy and two of the three transferase genes are highly specific to 0111. Bands of the wrong size found in amplified DNA are assumed to be due to chance hybridisation of genes widely present in EL. coli . The primers, annealing temperatures and positions for each gene are in (Table 5) . The 0111 assay was also performed using pools including DNA from O antigen expressing Yersinia pseudotuberculosis , Shigella boydii and Salmonella enterica strains (Table 5A) . None of the oligonucleotides derived from wbdH, wzx, wzy or wbdM gave amplified DNA of the correct size with these pools. Notably, pool number 25 includes £L enterica Adelaide which has the same 0 antigen as E. coli 0111: this pool did not give a positive PCR result for any primers tested indicating that these genes are highly specific for E. coli 0111. Each of the 12 pairs binding to wbdH, wzx, wzy and wbdM produces a band of predicted size with the pools containing 0111 DNA (pools number 22 to 24) . As pools 22 to 24 included DNA from all strains present in pool 21 plus 0111 strain DNA (Table 2), we conclude that the 12 pairs of primers all give a positive PCR test with each of three unrelated 0111 strains but not with any other strains tested. Thus these genes are highly specific for E. coli 0111. C. Primers based on the EL . coli 0157 O antigen gene cluster sequence. Two or three primer pairs for each of the transferase, wzx and wzy genes of 0157 were tested against _____ coli chromosomal DNA of pools 1 to 19, 29 and 30 (Table 6) . For wbdN, three pairs of primers, which bind to various regions of this gene, were tested and found to be specific for 0157 as there was no amplified DNA in any of those 21 pools of EL . coli chromosomal DNA tested. Three pairs of primers for wbdO were tested, and they are all specific although primers # 1211/#1212 produced two or three bands of the wrong size from all pools. Three pairs of primers were tested for wbdP and they all were specific. Two pairs of primers were tested for wbdR and they were all specific. For wzy, three pairs of primers were tested and all were specific although primer pair #1203/#1204 produced one or three bands of the wrong size in each pool. For wzx, two pairs of primers were tested and both were specific although primer pair #1217/#1218 produced 2 bands of wrong size in 2 pools, and 1 band of wrong size in 7 pools. Bands of the wrong size found in amplified DNA are assumed to be due to chance hybridisation of genes widely present in EL. coli . The primers, annealing temperatures and function information for each gene are in Table 6. The 0157 assay was also performed using pools 37 to 42, including DNA from 0 antigen expressing Yersinia pseudotuberculosis , Shigella . boydii , Yersinia enterocolitica 09 , Brucella abortus and Salmonella enterica strains (Table 6A) . None of the oligonucleotides derived from wbdN, wzy, wbdO, wzx, wbdP or wbdR reacted specifically with these pools, except that primer pair #1203/#1204 produced two bands with Y ^ _ enterocolitica 09 and one of the bands is of the same size with that from the positive control. Primer pair #1203/#1204 binds to wzy. The predicted secondary structures of Wzy proteins are generally similar, although there is very low similarity at amino acid or DNA level among the sequenced wzy genes. Thus, it is possible that _____ enterolcolitica 09 has a wzy gene closely related to that of EL. coli 0157. It is also possible that this band is due to chance hybridization of another gene, as the other two wzy primer pairs (#1205/#1206 and #1207/#1208) did not produce any band with Y ^ enterocolitica 09. Notably, pool number 37 includes £A enterica Landau which has the same 0 antigen as EL. coli 0157, and pool 38 and 39 contain DNA of B. abortus and Y___ enterocolitica 09 which cross react serologically with EL. coli 0157. This result indicates that these genes are highly 0157 specific, although one primer pair may have cross reacted with Y___ enterocolitica 09. Each of the 16 pairs binding to wbdN, wzx, wzy, wbdO, WjdP and wbdR produces a band of predicted size with the pools containing 0157 DNA (pools number 31 to 36) . As pool 29 included DNA from all strains present in pools 31 to 36 other than 0157 strain DNA (Table 3), we conclude that the 16 pairs of primers all give a positive PCR test with each of the five unrelated 0157 strains. Thus PCR using primers based on genes wbdN, wzy, wbdO, wzx, wbdP and wbdR is highly specific for EL_ coli 0157, giving positive results with each of six unrelated 0157 strains while only one primer pair gave a band of the expected size with one of three strains with 0 antigens known to cross-react serologically with EL_ coli 0157. D. Primers based on the Salmonella enterica serotype C2 and B 0 antigen gene cluster sequences . We also performed a PCR using primers for the S . enterica C2 and B serogroup transferases, wzx, wzy and genes (Tables 7 to 9) . The nucleotide sequences of C2 and B O antigen gene clusters are listed as SEQ ID NO : 3 (Fig. 9) and SEQ ID NO: 4 (Fig. 10 ) respectively. Chromosomal DNA from all the 46 serotypes of Salmonella enterica (Table 9) was isolated using the Promega Genomic isolation kit, 7 pools of 4 to 8 samples per pool were made. Salmonella enterica serotype B or C2 DNA was omitted from the pool for testing primers of 46 respective serotypes but added to a pool containing 6 other samples to give pool number 8 for use as a positive control. PCR reactions were carried out under the following conditions: denaturing, 94°C/30"; annealing, temperature varies (see below) /30"; extension, 72°C/1'; 30 cycles. PCR reaction was carried out in a volume of 25μL for each pool. After the PCR reaction, 10μL PCR product from each pool was run on an agarose gel to check for amplified DNA. For pools which gave a band of correct size, PCR was repeated using individual chromosomal samples of that pool, and agarose gel was run to check for amplified DNA from each sample . The Salmonella enterica serotype B O antigen gene cluster (of strain LT2 ) was the first O antigen gene cluster to be fully sequenced, and the function of each gene has been identified experimentally [Jiang, X. M. , Neal, B., Santiago, F., Lee, S. J. , Romana, L. K. , and Reeves, P. R. (1991) "Structure and sequence of the rfb (O antigen) gene cluster of Salmonella serovar typhimurium (strain LT2 ) . " Mol. Microbiol. 5(3), 695-713; Liu, D. , Cole, R. , and Reeves, P. R. (1996). "An O antigen processing function for Wzx (RfbX) : a promising candidate for O-unit flippase" J. Bacteriol., 178 (7 ), 2102-2107 ; Liu, D. , Haase, A. M. , Lindqvist, L., Lindberg, A. A., and Reeves, P. R. (1993). "Glycosyl transferases of O-antigen biosynthesis in S. enterica : identification and characterisation of transferase genes of groups B, C2 and El." J. Bacteriol., 175, 3408-3413; Liu, D., Lindquist, L., and Reeves P. R. (1995). "Transferases of O-antigen biosynthesis in Salmonella enterica : dideoxhexosyl transferases of groups B and C2 and acetyltransferase of group C2." " j. Bacteriol./ 177, 4084-4088; Romana, L. K., Santiago, F. S., and Reeves, P. R. (1991). "High level expression and purification dThymidine-diphospho-D-glucose 4,6 dehydratase ( rfbB) from Salmonella serovar typhimurium LT2. " BBRC, 174, 846-852]. One pair of primers for each of the pathway genes and wbaP was tested against the pools of Salmonella enterica DNA, two to three pairs of primers for each of the other transferases and wzx genes were also tested. See Table 8 for a list of primers and functional information of each gene, as well as the annealing temperature of the PCR reaction for each pair of primers. For pathway genes of group B strain LT2 , there are 19/45, 14/45, 15/45, 12/45, 6/45, 6/45, 6/45, 6/45, 1/45, 9/45, 8/45 positives for rmlB, rmlD, rmlA, rmlC, ddhD, ddhA, ddhB, ddhC, abe , manC, and manB repsectively (Table 9) . For the LT2 wzx gene we used three primer pairs each of which gave 1/45 positive. For the 4 transferase genes we used a total of 9 primer pairs. 2 primer pairs for wbaV gave 2/90 positives. For 3 primer pairs of wbaN, 11/135 gave a positive result. For the wbaP primer pair 10/45 gave a positive result (Table 9). The experimental data show that oligonucleotides derived from the wzx and wbaV group B O antigen genes are specific for group B 0 antigen amongst all 45 Salmonella enterica O antigen groups except O group 67. The oligonucleotides derived from Salmonella enterica B group wbaN and wbaU genes detected B group O antigen and also produced positive results with groups A, Dl and D3. WbaU encodes a transferase for a Mannose α(l-4) Mannose linkage and is expressed in groups A, B and Dl while wbaN, which encodes a transferase for Rhamnose α(l-3) Galactose linkage is present in groups A, B, Dl, D2 , D3 and El. This accounts for the positive results with the group B wbaU and wbaN genes . The wbaN gene of groups E and D2 has considerable sequence differences from that of groups A, B, Dl and D3 and this accounts for the positive results only with groups B, Dl and D3. The Salmonella enterica B primers derived from wzx and transferase genes produced a positive result with Salmonella enterica 067. We find that Salmonella enterica 067 has all the genes of the group B 0 antigen cluster. There are several possible explanations for this finding including the possibility that the gene cluster is not functional due to mutation and the group 067 antigenicity is due to another antigen, or the 0 antigen is modified after synthesis such that its antigenicity is changed. Salmonella enterica 067 would therefore be scored as Salmonella enterica group B in the PCR diagnostic assay. However, this is of little importance because Salmonella enterica 067 is a rare O antigen and only one (serovar Crossness) of the 2324 known serovars has the 067 serotype [Popoff M.Y. et al (1992) "Antigenic formulas of the Salmonella enterica serovars" 6th revision WHO Collaborating Centre for Reference and Research on Salmonella enterica, Institut Pasteur Paris France] , and serovar Crossness had only been isolated once [M. Popoff, personal communication] . The Salmonella enterica B primers derived from wbaP reacted with group A, C2 , Dl, D2 , D3 , El, 54, 55, 67 and E4 O antigen groups. WbaP encodes the galactosyl transferase which initiates 0 unit synthesis by transfer of Galactose phosphate to the lipid carrier Undecaprenol phosphate. This reaction is common to the synthesis of several 0 antigens . As such wba is distinguished from other transferases of the invention as it does not make a linkage within an 0 antigen. We also tested 20 primer pairs for the wzx, wzy and 5 transferase genes of serotype C2 and found no positives in all the 7 pools (Table 7) . Groups A, B, Dl, D2 , D3 , C2 and El share many genes in common. Some of these genes occur with more than one sequence in which case each specific sequence can be named after one of the serogroups in which it occurs. The distribution of these sequence specificities is shown in Table 10. The inventors have aligned the nucleotide sequences of Salmonella enterica wzy, wzx genes and transferase genes so as to determine specific combinations of nucleic acid molecules which can be employed to specifically detect and identify the Salmonella enterica groups A, B, Dl, D2 , D3 , C2 and El (Table 10). The results show that many of the O antigen groups can be detected and identified using a single specific nucleic acid molecule although other groups in particular D2 and El, and A and Dl require a panel of nucleic acid molecules derived from a combination of genes . It will be understood that in carrying out the methods of the invention with respect to the testing of particular sample types including samples from food, patients and faeces the samples are prepared by routine techniques routinely used in the preparation of such samples for DNA based testing.
