Resistant microbes are more difficult to treat, requiring higher doses, or alternative medications which may prove more toxic. The third plasmid, pA297-3, is 200 kb and carries the sul2 sulphonamide resistance gene and strAB streptomycin resistance gene within Tn 6172 and a mer mercuric ion resistance module elsewhere. Figure 1. These results suggest that pCK41 is a virulence plasmid of substantial importance in the E. tarda pathogenesis to fish. Plasmids associated with resistance to streptomycin, to streptomycin plus chloramphenicol or to tetracycline in Staphylococcus hyicus isolated from the skin of pigs have been compared, by restriction endonuclease digest patterns, with similar staphylococci from human sources and with published DNA base sequences. Plasmid pIP1203 was stable after 100 generations in Y. pestis 16/95 and E. coli K802N (frequency of loss <0.25%). From this streptomycin-sensitive plasmid vector recombinant molecules can thus be directly selected. Sequence determination of the insert in pAT710 revealed that the base composition of this fragment was 57.5% G+C, much higher than the average G+C content of the Y. pestis genome (46%)[16]. transformed plasmid, carrying the complex antibiotic resistance locus for ampicillin, kanamycin, neomycin, streptomycin, sulfathiozole, and trimethoprim, and the ehxA gene, was designated pO26-CRL. to high-level streptomycin resistance in lactic streptococci resides on the chromosome, and its expression is affected by a plasmid. A) Agarose-gel electrophoresis of EcoRV-digested plasmid DNA from representative Yersinia pestis strain 6/69 (1) and from streptomycin-resistant strain 16/95 (2).

Cloningandcharacterization ofthe streptomycin resistance genes frompPSR1.The 1.5-kb SacI-EcoRVfragment, which contains the Smr genes strA and strB from the broad-host-range plasmid RSF1010 (43), was used to identify homolo-gous sequences on plasmids from Cus Smr and Cur Smr strains ofP. Among the Sm Sa-resistant strains, the frequency of nonconjugative r (Sm Sa) plasmids was much higher than that of conjugative R plasmids encoding double resistance. However, 44.1% of the isolates from non-sprayed orchards were also resistant to streptomycin. The subclone DNA hybridized with enzyme-digested genomic or plasmid DNA of three of 17 other resistant strains of X. c. vesicatoria as well as with the DNA from streptomycin-resistant strains Psp 34 and Psp 36 of Pseudomonas syringae pv. Two potentially coding sequences of 801 bp and 834 bp identified in the insert were identical to the strA and strB genes that encode an aminoglycoside 3"-O-phosphotransferase [APH(3")-Ib] and a 6-O-phosphotransferase [APH[6]-Id], respectively[17]. Genetic organization of the strA-strB genes. Adding an antibiotic resistance gene to the plasmid solves both problems at once – it allows a scientist to easily detect plasmid-containing bacteria when the cells are grown on selective media, and provides those bacteria with a pressure to keep your plasmid. Upon mobilization, pRO161 acquires streptomycin resistance (Smr) andcansubsequentlyberemobilized bypMG1atsignificantly higherfrequencies than pRO161 itself. The plasmid profiles of strains C2, ML3, C2 Lac-, ML3 Lac-, and two kinds of transconjugants confirmed the presence of a plasmid of approximately 5.5 megadaltons in strains showing no mutation to high-level streptomycin resistance, while strains missing such a plasmid exhibited high-level streptomycin resistance after incubation with subinhibitory concentrations of the drug.
