[Clinical and molecular characterization of ESBL-producing enterobacteria isolated from bacteremia in a university hospital].

Introduction: Extended-spectrum-β-lactamases (ESBL) are plasmid-encoded enzymes that confer resistance to multiple antimicrobials. ESBL-producing enterobacteria that cause bacteremia limit therapeutic options and increase mortality.

Objective: To perform a clinical and molecular description of bacteremia caused by ESBL-producing enterobacteria.
