Molecular epidemiology of bla(CMY-2) plasmids carried by Salmonella enterica and Escherichia coli isolates from cattle in the pacific northwest

摘要

Restriction analyses of bla(CMY-2)-bearing plasmids and Salmonella and Escherichia coli hosts identified (i) shared highly similar plasmids in these species in rare cases, (ii) a clonal host-plasmid relationship in Salmonella enterica serotype Newport, and (iii) a very high diversity of strain types and plasmids among commensal E. coli isolates.
