Abstract

Genes encoding the CMY-2, CTX-M-14, and SHV-12 beta-lactamases were detected in three of five Escherichia coli isolates from fecal samples from healthy chickens which showed resistance or diminished susceptibility to extended-spectrum cephalosporins. A -42 mutation at the promoter region of the ampC gene was detected in the other two isolates.
