[Epidemiology of ESBL-positive Enterobacteriaceae in Mantova hospital (Italy)].

In a retrospective study concerning the epidemiology of extended-spectrum beta-lactamase (ESBL) positive Enterobacteriaceae during 2007-2008 in the wards of the Carlo Poma hospital in Mantova, Mercurio surveillance software was used to detect alert microorganisms. Our objective was to link the epidemiological data with the type of patient and ward, and to assess the risk factors for such infections in particular nosocomial environments. The study enabled the change in the relative epidemiological data to be detected, and showed that such bacteria can be found almost throughout the hospital.
