Extended-spectrum beta-lactamase CTX-M-1 in Escherichia coli isolates from healthy poultry in France

Appl Environ Microbiol. 2007 Jul;73(14):4681-5. doi: 10.1128/AEM.02491-06. Epub 2007 May 18.

Abstract

Genes encoding extended-spectrum beta-lactamase CTX-M-1 were detected in 12 Escherichia coli isolates recovered over a 7-month period from the ceca of healthy poultry in seven districts in France in 2005. Eleven of those strains were not clonally related and had a bla(CTX-M-1) gene located on transferable plasmids of different sizes and structures.
