A total of 122 samples were collected from the farms, slaughterhouses and retail shops/super markets as materials for this study. There were 90/122 samples positive with Campylobacter spp bacteria (accounted for 73.77%). The contamination rate of each sample type as follows the fecal samples: 83.3% (25/30 samples), the cecum samples: 95.45% (42/44 samples), and chicken meat samples: 47.92% (23/48 samples). The result of testing susceptibility of 150 Campylobacter bacteria strains with eight common antibiotics showed that 100 % of Campylobacter bacteria strains resisted to at least 2 antibiotics. The antibiotic resistant rate of Campylobacter bacteria strains was quite high, ranging from 52.67% (resisted to nitrofurantoin) to 100% (resisted to ampicilline). The result of this study indicated that the risk of antibiotic resistance in treatement for human suffering with Campylobacter bacteria infection is very high.
