Description:
This is a division of Application Ser. No. 09/402,039, filed Dec. 23, 1999, abandoned, which is a §371 U.S. national phase application of PCT/EP98/01720 filed Apr. 1, 1998. 
    
    
     BACKGROUND OF THE INVENTION 
     The invention relates to bacterial plasmids. 
     FIELD OF THE INVENTION 
     Plasmids are small, extra-chromosomal, mostly circular and independently replicating DNA molecules, which occur in nearly all bacteria and also in some eukaryons as well as in the mitochondria. The size of the plasmids vary between approximately 1.5 to 300 kb. 
     As a rule bacterial plasmids are circular, covalently closed and supercoiled. They often carry resistance genes against antibiotics or heavy metals, genes for the metabolization of a typical substrates or genes for a number of specie-specific characteristics, such as metabolic properties or virulence factors. Some plasmids can be transferred from one cell into another. Because the pathogenity of bacteria is determined according to present views, partly also by the properties of the plasmids, there exists increasingly a greater interest to clarify the properties of the plasmid DNA. 
     It is known of the family of entereobacteriacea, to whom 14 main varieties and 6 further varieties belong, that family members can develop different properties. Typical family members are, for example, Escherichia, Salmonella and Klebsiella.  Escherichia coli  ( E. coli ) is the classic model for the study of bacterial genetics. By discovering and characterizing different virulence factors of  E. coli , strains of this species were generally found to exhibit differences in human and animal pathogenicities. These differences may be extreme, ranging from avirulence to high grade virulence, such as in the case of the recently spreading variant known as “EHEC”. Thus, a number of virulence factors have been described for extra-intestinal as well as for intestinal  E. coli  strains, which have been partially characterized. The sero-variety 06:K5 virulence factors, such, as for example, haemolycin and P-fimbrial adhesion are known to be associated with pathogenic  E. coli , while apathogenic representations of this sero-variety typically lack these virulence factors. 
     As in rule virulence genes are found at enterobacteria on large plasmids (approximately 60 kb). There are also enterobacteria with small, so-called cryptic plasmids, whose function hitherto could not be reliably determined. 
     SUMMARY OF THE INVENTION 
     Because it is known that  E. coli  virulence factors are at least partly also present in genes of the plasmids, there exists a need for further, data regarding the detection and characterization of plasmids in enterobacteria, especially Escherichia. Such information will improve, for example, diagnostic and therapeutic treatment of enterobacterial infections. Such plasmids, or their bacterial carriers, or corresponding synthethized DNA can be applied medicinally in therapeutics or for prophylaxis of Enterobacterial infections, as well as for nutritional, physiological or probiotic purposes in microbiological analysis or diagnostics testing of such infections. Furthermore, plasmids, especially those of  E. coli , are known expression vectors used in genetic engineering, increasing the interest in and learning more about the properties of such plasmids.

     DETAILED DESCRIPTION OF THE INVENTION 
     Molecular genetic investigations with the  E. coli  strain DSM 6601 were performed for this purpose. The DNA sequences obtained from this strain were examined with the help of data bank programs of DNA sequence analysis and compared with already existing DNA sequences of other bacteria. 
     The strain DSM 6601 contains two small plasmids with a size of 3177 or 5552 bp, which are described respectively as pMUT1 or pMUT2. 
     The DNA of the smaller plasmids pMUT1 were sub-cloned as a linear fragment into the vector pUC18, after restrictional fission with the enzyme HindIII, the DNA sequence was subsequently determined. This is evident from the enclosed FIG. 1 (SEQ ID NO.: 1). The resulting DNA sequence was examined by means of a homologous comparison with the GenEMBL data bank; the results of this comparison are given in FIG.  2 . 
     For this comparison the HindIII intersection was fixed as Position 1. From the position 200 to 800 bp the DNA of the plasmid pMUT1 exhibits significant homologies to different reduplication starting positions (origins of replication) of other enterobacterial plasmids, especially to the plasmids NTP1, NTP16 and CloDF13. In the region of position 950 bp, a 570 bp sized homology starts to the plasmid NTP16, which originally was isolated from Salmonella Typhimurium. This homology contains the mobA-gene, which is necessary for the mobilizability of the plasmids NTP16 as well as for an origin of transfer (oriT). Furthermore, significant homologies to the gene parA and cer were found from position 1790 up to 1920 bp, which are significant for the stability and the continuous transfer and distribution of plasmid molecules during cell division. For the remaining DNA regions, no significant homology could be identified. 
     Furthermore, the DNA sequence of the plasmid pMUT1 were transcribed into an amino acid sequence and analyzed for the existence of open reading frames. Six different reading frame possibilities were investigated. In total, 5 open reading frames with a size of 143, 62, 56, 49 and 48 amino acids could be found. A graphic representation of the analysis is given in FIG.  3 . 
     The DNA of the larger plasmid pMUT2 were likewise sub-cloned after linearization with the restriction enzyme Sphl into the vector pUC18 and subsequently were sequenced completely. The DNA sequence is given in FIG. 4 (SEQ ID NO.: 2). The DNA sequence obtained in this manner was investigated with the help of the GeneEMBL data bank program for homologies with known DNA sequences. The result is graphically represented in FIG.  5 . The DNA of the plasmid pMUT2 exhibits significant homologies to the replication region of different ColE1 plasmids of  E. coli  in the position 890 up to 1660 bp. A further significant homology to CoE1 plasmids is found in the region of position 3800 up to 4950 bp. Here it concerns homologies for the mobilization region of ColE1 plasmids. In the area of position 3770 up to 4980 bp, homologies were found to a plasmid of the  Pasteurella haemolytica  strain A1. There are genes on this plasmid which encode for anti-microbial resistance proteins in Pasteurella. However, the homology stretches over the intergenetic region, so that it possibly also concerns sequences that are necessary for the mobility of the plasmids. 
     Two regions were identified, which exhibit significant homologies to other enterobacterial plasmids. These hemologous regions concerns the origin-of-replication-regions and mob-regions, which are necessary for the mobilizability of the plasmids. For pMUT2 no significant homology could be identified for the remaining DNA sections. 
     The DNA sequence of the plasmid pMUT2 was subsequently circumscribed into an amino acid sequence and analyzed for the existence of open reading frames. The results are graphically represented in FIG.  3 . Five open reading frames with amino acid sequences in the order of 327, 318, 264, 76 and 63 amino acids were found. 
     The previously unknown plasmids pMUT1 and pMUT2, were not known heretofore to be present either alone or in combination in  E. coli  strains or other enterobacteria. 
     The occurrence of the plasmids may be related to the metabolic and medicinal and/or nutritional, physiological, or probiotic usable properties of the strain DSM 6601. 
     The investigation of the plasmids allows a more precise determination and analysis of enterobacteria, especially the Escherichia groups. Furthermore, these plasmids offer themselves as reliable expression vectors for genetic engineering. 
     The invention shall now be further explained by way of examples: 
     EXAMPLE 1 
     Plasmid Isolation. 
     The isolation of the plasmid DNA occurred according to the process of Birnboim et al. (Birnboim, A.C. und Doly, J. (1979) Nucl. Acids Res. 7:1513-1523 A rapid alkaline extraction procedure for screening recombinant plasmid DNA). 
     3 ml LB-medium were inoculated with a bacteria colony and agitated overnight at 37° C. This culture is centrifuged off in an Eppendorf vessel, the medium residue is removed by means of a pipette. The cell sediment is re-suspended with 100 μl of solution I (50 mM glucose; 10 mM EDTA, pH 8; 25 mM Tris-HCl, pH 8). After 5 minutes of incubation at room temperature 200 μl of solution II (0,2 N NaOH; 1% SDS) is added, mixed until clarification and the Eppendorf vessel is left on ice for a further 5 minutes. Then 150 μl of solution III (3 M Na-acetate, pH 4.8)is added thereto, agitated briefly until the chromosomal DNA precipitates flocculantly, and the sediment is left again on ice for 5 minutes. The precipitated chromosomal DNA and the cell residues are pelletized for 5 minutes in the centrifuge and the residue with the plasmid DNA is transferred to a new vessel. For the purification of the plasmid DNA, 50 μl phenol and 150 μl chloroform/isoamyl alcohol (24:1) are added and after brief agitation centrifuged off for 2 minutes. The aqueous phase is pipetted into a new vessel. The plasmid DNA is precipitated with 2 volumes ice-cold ethanol and centrifuged off for 10 minutes. The pellet is washed with 70% ethanol and dried in the Speedvac. The plasmid DNA is re-suspended in 20 μl H 2 O bidest  and preserved at −20° C. 
     EXAMPLE 2 
     DNA Sequencing 
     The DNA sequencing occurs according to the process of F. Sanger et al. (Sanger, F., Nicklen, S. and Coulson, A. R. (1977) Proc. Natl. Acad. Sci. USA 74:5463-5467 DNA sequencing with chain terminating inhibitors). 
     The DNA sequencing occurs with the T7-sequencing kit of the company Pharmacia LKB. 
     For the denaturization step 8 μl (1.5 up to 2 μg) plasmid DNA is mixed with 2 μl 2 N NaOH, briefly centrifuged off and incubated for 10 minutes at room temperature. The DNA is precipitated with 3 μl 3 M Na-acetate, pH 4.8 as well as 7 μl H 2 O bidest  and 60 μl ice-cold ethanol absolute  for 15 minutes at −70° C. The precipitated DNA is centrifuged off for 10 minutes, washed with 70% ethanol and dried. 
     For the annealing reaction the denaturated DNA is suspended in 10 μl H 2 O bidest  and mixed with 2 μl annealing powder and 2 μl primer (40 ng). The sediment is incubated for 20 minutes at 37° C., so that a bonding of the primer to the template-DNA can occur. The reaction sediment is cooled down for 10 minutes at room temperature and then either immediately used for the labelling reaction or is frozen at −20° C. For the labelling reaction 3 μl labelling mixture, 1 μl [α-P 32 ]dATP and 2 μl T7-polymer (the T7-polymer was diluted 1:5 with enzyme dilution powder) are pipetted in the annealing reaction sediment and after briefly mixing are incubated for 5 minutes at room temperature. Meanwhile the already prepared sequencing mixture for the termination reaction (each 1 vessel with 2.5 μl ‘G’-, ‘A’-, ‘T’- and ‘C’-Mix “short”) is preheated at 37° C. After completion of the labelling reaction 4 μl thereof is added to each of the four sequencing mixtures and briefly mixed by means of the pipette. The termination reactions are incubated for 5 minutes at 37° C. For the conclusion of the termination reaction 5 μl stop solution is added respectively. The sediments are now transferred into an incubator at 95° C., denaturized for 2 minutes and then placed on ice. Each 2.5 μl of the reactions are spread on a sequencing gel [25.2 g carbamide, 22 ml H 2 O bidest , 6 ml 10× TBE, 10 ml polyacryl amide (40%), 2 ml ammonium persulfate (16 mg/ml), 60 μl TEMED] in the sequence of a ‘G’, ‘A’, ‘T’, ‘C’. The electrophoresis occurs at 40 Watt and 1500 Volt for 4.5 hours.
