Molecular Epidemiology of blaCMY-2 Plasmids Carried by Salmonella enterica and Escherichia coli Isolates from Cattle in the Pacific Northwest

摘要

Restriction analyses of blaCMY-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.
