Plasmid resistance to ampicillin in Salmonella typhi.
A Salmonella typhi strain resistant to ampicillin, streptomycin and sulfonamides was isolated in Catania in 1988. It has been shown that these resistances were encoded by an auto-transferable R-plasmid, of molecular weight 70 Md, belonging to the incompatibility group B.
