Molecular characterization of AmpC-producing Escherichia coli clinical isolates recovered in a French hospital

Abstract

This work sheds new light on the spread of ESAC beta-lactamases in E. coli. It showed that this emerging mechanism of resistance could be as frequent as plasmid-mediated cephalosporinases (0.21% and 0.28% of the E. coli isolates, respectively) and that a phenotypic approach is not able to identify these mechanisms of resistance.
