Thirty-one Campylobacter jejuni isolates (22 from various local sources, 9 from imported chicken meats) were subtyped with PFGE and flaA typing to investigate their genetic relatedness. Based on a 90% similarity criterion, 23 and 21 genotypic patterns were formed by PFGE and flaA typing, respectively. The discriminatory indices for PFGE, flaA typing, and a composite analysis of PFGE and flaA typing were 0.9785, 0.9527, and 0.9871, respectively. Similar patterns in composite analysis were observed between sources (cattle and chicken, and cattle and human), indicating that reservoir animals may have been the source of human campylobacteriosis. Therefore, strict hygiene measures from farm to table should be implemented to prevent diseases due to C. jejuni in humans.
