Spread of Extended-Spectrum β-Lactamase CTX-M-Producing <i>Escherichia coli</i> Clinical Isolates in Community and Nosocomial Environments in Portugal

20 Mar 2007

Abstract excerpt

Of the 181 unduplicated Escherichia coli strains isolated in nine different hospitals in three Portuguese regions, 119 were extended-spectrum beta-lactamase (ESBL)-CTX-M producers and were selected for phenotype and genotype characterization. CTX-M producer strains were prevalent among community-acquired infections (56%), urinary tract infections (76%), and patients >/=60 years old (76%). In MIC tests, all...
