摘要: [目的]掌握河南省鸡源结肠弯曲杆菌的分布和对抗菌药物的耐药情况。[方法]从养殖场抽取鸡泄殖腔拭子460份进行结肠弯曲杆菌分离培养,采用PCR、基质辅助激光解吸电离飞行时间质谱进行鉴定,并通过微量肉汤稀释法对分离菌株进行药物敏感性分析。[结果]共分离结肠弯曲杆菌42株,分离率为9.13%;分离的结肠弯曲杆菌对环丙沙星、萘啶酸、阿奇霉素耐药严重,耐药率分别为95.24%、90.48%、71.43%。[结论]河南省鸡源结肠弯曲杆菌耐药情况较为严重,应规范使用抗菌药物。

Abstract: [Objective] To characterize the distribution and antibiotic resistance pattern of Campylobacter coli from chickens in Henan Province. [Method] A total of 460 cloaca swab samples were collected from chicken farms to isolate the Campylobacter coli strains. The confirmative identification of the isolates was performed using PCR assay and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The antimicrobial susceptibility test was carried out with broth micro-dilution method. [Result] A total of 42 Campylobacter coli strains were obtained with an isolating rate of 9.13%. High levels of resistance to ciprofloxacin, nalidixic acid and azithromycin were observed, and the resistant rate was 95.24%, 90.48% and 71.43%, respectively. [Conclusion] The antimicrobial resistant Campylobacter coli strains isolated from chickens are prevalent in Henan Province. Further attention should be given to the prudential use of veterinary antibiotics.

Key words: Campylobacter coli from chickens, isolation and identification, antibiotic resistance analysis
