Abstract:
A total of 244 CMY-2 plasmids from 5 separate studies involving Escherichia coli and Salmonella human clinical cases as well as E. coli from feedlots and water sources were examined. Genetically similar CMY-2 plasmids isolated from either E. coli or Salmonella from human, animal, and environmental sources are widely distributed across Canada and cluster into replicon types I1, A/C, and K/B and an unidentified group.
Keywords:AmpC   Canada   Plasmids   Enterobacteriaceae
