Using the PCR technique, the presence of the seven genotypie virulence markers of Campylobacter has been tested. It was found that all C. coli (92 strains) and C. jejuni (105 strains) possessed the flaA and cadF markers. Several strains were positive for the CDT toxin genes (76.6%, 85.3%, and 83.2% strains with the A, B, and C cdt gene variants, respectively). On the other hand, only 66.0% and 20.8% isolates had the iam and virB genes.
