The Campylobacter detection is performed by conventional culture methods and the identification of Campylobacter jejuni and Campylobacter coli is principally based on the hippurate hydrolysis test. The two major drawbacks of this biochemical test for species identification include the inconsistency of the results and the presence of atypical strains, which can lead to the misidentification of an isolate. As an alternative, multiplex polymerase chain reaction (mPCR) protocols for the simultaneous detection and identification of different Campylobacter species have been developed. This study examined the performances of an experimental BAX System assay for the C. jejuni and C. coli identification in comparison to a multiplex PCR protocol recently published. The samples tested were represented by 106 environmental swabs collected on Teflon strips and tables, stainless steel saws, hooks and trays, ceramic floors and walls, as well as equipment surfaces, located in a swine (N=50) and a poultry (N=56) slaughterhouse. The highest Campylobacter detection rate was obtained after 48 h of enrichment by using both the PCR procedures. After 24 h, the BAX System provides a more rapid and accurate Campylobacter detection and identification assay than the multiplex PCR. Except for two samples, all the broths where Campylobacter cells were detected after 24 or 48 h of enrichment, with at least one of the PCR protocols, gave Campylobacter colonies using the culture method.
