In the last few years, various PCR based methods have been developed that enable detection of Cronobacter spp. to the genus and species level. Moreover, several real-time PCR based systems for detection of Cronobacter spp. are available, however, comparative evaluation studies are not available. The current study represents a comparative evaluation of three commercial diagnostic systems, namely the BAX® System PCR Assay Enterobacter sakazakii (DuPont, Qualicon, Wilmington, USA), the Assurance GDS™ Enterobacter sakazakii (BioControl, Bellvue, USA) and the foodproof® Enterobacter sakazakii Detection Kit (Biotecon Diagnostics, Potsdam, Germany) for the rapid identification of Cronobacter spp. Twenty-one target and non-target strains were included in the study and results were compared for specificity and convenience in performance. A specificity of 100% was observed for two of the three real time PCR systems tested, namely the Assurance GDS™ Enterobacter sakazakii and the foodproof® Enterobacter sakazakii Detection Kit for pure cultures as well as artificially contaminated powdered infant formula (PIF) samples.
