Molecular characterization and antimicrobial susceptibility of extended-spectrum {beta}-lactamase-producing Enterobacteriaceae isolates at a tertiary-care centre in Monterrey, Mexico.

Abstract excerpt

Our objective was to analyse phenotypic and genetic data of extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae, Enterobacter cloacae, Escherichia coli and Serratia marcescens that cause infections in our hospital. Over a 3 year period, 342 randomly selected clinical Enterobacteriaceae isolates were tested for ESBL production and evaluated for the presence of the β-lactamase genes bla(SHV),...
