Molecular Diversity of ESBL-Producing Escherichia coli from Foods of Animal Origin and Human Patients.

ABSTRACT: Dissemination of enterobacteria that produce extended spectrum β-lactamases (ESBL) throughout the food chain has become an important health concern. This work aimed to evaluate the occurrence of ESBL-producing bacteria in foods of animal origin and to investigate the similarities between food and human isolates. The presence of beta-lactam-resistant Enterobacteriaceae was analyzed in 108 food samples, isolating 10 strains of Escherichia coli, one strain of Citrobacter freundi, and one of Hafnia alvei. E. coli isolates were compared to a group of 15 strains isolated from human patients by antibiotic susceptibility testing, characterization of ESBL genes (bla_TEM, bla_CTX,), multilocus sequence typing (MLST) and pulse-field gel electroph
