Abstract

Abstract: In order to investigate the prevalence of AmpC-type β-lactamase among 16S rRNA methylase-producing Escherichia coli strains isolated from diseased chickens in Henan province,158 16S rRNA methylase-producing E. coli strains isolated from diseased chickens during the years 2005 to 2008 were subjected to PCR for the presence of AmpC-type β-lactamase. The results revealed that of 158 16S rRNA methylase-producing E. coli strains, the positive rates of CMY-2, DHA-1 were 34.8% and 36.1%, respectively, suggesting AmpC-type β-lactmase were prevalent among 16S rRNA methylase-producing E. coli strains isolated from diseased chickens in Henan province.

Key words: Escherichia coli; AmpC; β-lactamase; resistance
