| Abstract: | A plasmid pDEP34 that codes for resistance to ampicillin, streptomycin, sulphonamides and tetracyclines has been identified in strains of Salmonella typhimurium phage type 193 which have become increasingly common in England and Wales since 1988. pDEP34 is also self-conjugative, carries the genes responsible for the virulence of host strains for BALB/c mice ( spv genes) and is closely related to the Salm. typhimurium 'serotype-specific' plasmid pSLT. |
