[Fecal colonization by extended-spectrum beta-lactamase-producing Klebsiella pneumoniae in a neonatal intensive care unit].

Background: Fecal colonization by multiresistant bacteria can be a source of nosocomial infections. The aim of this work was to study fecal colonization by Klebsiella pneumoniae in neonatal intensive care unit (NICU) patients and investigate the resistance profiles of the strains.

Methods: From May to October 2001, 11 stool specimens were collected from each patient hospitalized in the NICU during this period (425 specimens).
