Abstract

Cattle Diseases - microbiology Escherichia coli - drug effects Escherichia coli Infections - microbiology Salmonella enterica - genetics Plasmids - classification Restriction Mapping DNA, Bacterial Genetic Variation Salmonella enterica - drug effects Animals beta-Lactamases - genetics Molecular Epidemiology Cattle Escherichia coli - genetics Escherichia coli - isolation & purification Plasmids - genetics Salmonella Infections, Animal - microbiology Northwestern United States Salmonella enterica - isolation & purification Escherichia coli Infections - veterinary beta-Lactam Resistance - genetics
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.
