Campylobacter jejuni and C. coli isolates from poultry, cattle, and humans were studied using pulsed-field gel electrophoresis (PFGE) and PCR of candidate livestock-associated marker genes. Human isolates showed 5.7 and 61% overlap with cattle and poultry isolates, respectively, by use of PFGE. No unambiguous association was found between marker genes (the Cj1321 and Cj1324 genes) and livestock-associated isolates.
