title: Characterization of blaTEM-52-carrying plasmids of extended-spectrum-β-lactamase-producing Salmonella enterica isolates from chicken meat with a common supplier in Japan.
abstract: The acquisition of resistance to cephalosporins among Salmonella spp. is a major public health concern. This study identified clonal plasmids carrying bla(TEM-52) from 10 Salmonella enterica serovar Infantis and Manhattan isolates from retail chicken meats that originated from a common supplier in Japan. Whole-genome analyses of the representative plasmids, including pYM4, revealed that they are 38 kb in size and that pYM4 is identical to pDKX1 from beef in Denmark, suggesting a global dissemination of resistance mediated by the plasmids.
