Use of automated repetitive-sequence-based PCR for rapid laboratory confirmation of nosocomial outbreaks.
Rapid and reliable diagnosis of genetic relatedness of clinical isolates in microbiologic laboratory is essential in case of nosocomial outbreak investigation. Most molecular techniques used to type microorganisms are technically demanding and time consuming. Currently repetitive-sequence-based PCR (rep-PCR) technique has been adapted to an automated format on the DiversiLab system (bioMérieux, Marcy l'Etoile, France). Aim of this study was to compare the performance of the DiversiLab system to that of pulsed-field gel electrophoresis (PFGE) in nosocomial outbreaks. ⋯ Automated rep-PCR assays on the DiversiLab system were used for MRSA, A. baumannii and for the first time ESBL-producing Klebsiella spp. and proved as a rapid and reliable method for molecular analysis of nosocomial outbreaks.
