Molecular epidemiology of blaCMY-2 plasmids carried by Salmonella enterica and Escherichia coli isolates from cattle in the Pacific Northwest

Appl Environ Microbiol. 2007 Dec;73(24):8005-11. doi: 10.1128/AEM.01325-07. Epub 2007 Oct 12.

Abstract

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.
