Epidemiology of extended spectrum beta-lactamase producing Enterobacter bacteremia in a brazilian hospital

Rev Soc Bras Med Trop. 2010 Jul-Aug;43(4):452-4. doi: 10.1590/s0037-86822010000400022.

Abstract

Introduction: Enterobacter can be included in the group of extended spectrum beta-lactamases (EBSL)-producing bacteria, though few studies exist evaluating risk factors associated with this microorganism. A retrospective cohort study was conducted to determine risk factors associated with ESBL-producing-Enterobacter and mortality

Methods: A retrospective cohort study with 58 bacteremia caused by ESBL-producing-Enterobacter (28 cases) and non-ESBL (30 cases)

Results: Risk factors associated with ESBL-Enterobacter were trauma, length of hospitalization, admission to the intensive care unit, urinary catheter and elective surgery (p< 0.05). The survival curves were similar for ESBL and non-ESBL CONCLUSIONS: ESBL-producing-Enterobacter bacteremia is prevalent and the survival curve was similar to non-ESBL-producing strains.
