Caracterización fenotípica y genotípica de la resistencia enzimática a las cefalosporinas de tercera generación en Enterobacter spp. / [Phenotypic and genotypic characterization of resistance to third-generation cephalosporins in Enterobacter spp]

ABSTRACT

Enterobacter spp. are becoming increasingly frequent nosocomial pathogens with multiple resistance mechanism to beta-lactam antibiotics. We carried out the phenotypic and genotypic characterization of beta-lactamases in 27 Enterobacter spp. (25 Enterobacter cloacae y 2 Enterobacter aerogenes), as well as the ability of different extended spectrum-lactamase (ESBL) screening methods. Resistance to third generation cephalosporins was observed in 15/27 (63
