Article originalÉpidémiologie des bêtalactamases à spectre étendu (BLSE) chez les entérobactéries dans un hôpital du sud de la France, 1999–2007Epidemiology of extended spectrum beta-lactamases (ESBL) Enterobacteriaceae in a General Hospital, South of France, 1999–2007

Purpose of the study The global epidemiology of extended spectrum betalactamases (ESBL) producing Enterobacteriaceae has evolved in recent years with the emergence of a new type of ESBL: CTX-M, mainly in Escherichia coli. These CTX-M type producing Enterobacteriaceae are responsible for both nosocomial and, more recently, community infections, including urinary tract infections. The aim of our work is to study ESBL producing Enterobacteriaceae evolution between 1999 and 2007 in the population from the Centre Hospitalier du Pays-d’Aix (CHPA), a general hospital from South of France.
