[Evaluation of the in vitro activity of meropenem against strains of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae isolated in the city of Fortaleza, Ceará].

Extended-spectrum beta-lactamases are plasmid-mediated. These enzymes have the ability to hydrolyze beta-lactam antibiotics. In this study, we evaluated the in vitro activity of meropenem against ESBL-producing Klebsiella pneumoniae strains.
