Abstract
The number of emerging pathogenic species described within the genus Arcobacter has increased rapidly during the last few years. In this work a genus-specific polymerase chain reaction (PCR) assay was developed for detection of the species of Arcobacter most commonly associated with foods. The assay uses primers designed to amplify an 85 bp DNA fragment on the 16S rRNA gene and was applied to the detection of Arcobacter spp. in retail chicken meat. Primer specificity was tested against a panel of Arcobacter spp., related Campylobacter and Helicobacter spp. and other food bacteria. Arcobacter primers consistently and selectively amplified the expected DNA fragment in all tested Arcobacter spp. Bacterial control primers confirmed the presence of amplifiable DNA in the samples. The applicability of the PCR assay to food was validated through screening of fresh retail chicken samples for the presence of Arcobacter spp., with a result of 45% (23 out of 51) positive samples. The genus-specific PCR assay developed has the potential to be used as a quick and sensitive alternative method for the survey of Arcobacter contamination in meats.
