In May 2006, a consultant microbiologist noted two isolates of extended spectrum beta-lactamase (ESBL)-producing Escherichia coli associated with urinary tract infections in a single week in two residents in a nursing home in Ireland. On review, five additional patients with ESBL-producing E. coli positive urine cultures were identified from that the same nursing home in the period January to May 2006. The general practitioners (GP) caring for these patients and the regional department of public health were informed, and a multidisciplinary outbreak team meeting was convened. A case was defined as any resident with significant ESBL-producing E. coli bacteriuria (> 100 000 CFU/ml) identified in 2006. In 2005, 56 ESBL producing isolates were detected in the region, but only one of these was from this nursing home, and this case had occurred seven months before January 2006, when the primary case in this outbreak had been reported. The nursing home was visited by members of the outbreak team and data on all residents were collected. Information was provided to residents and consent obtained for collection of rectal swabs to determine the prevalence of colonisation. (Extrait)
