Introduction. Campylobacter is one of the leading bacterial causes of food-borne disease. The prevalence of Campylobacter species resistant to antimicrobial agents is increasing. This study is intended to determine prevalence and antimicrobial susceptibility patterns of Campylobacter species among under-five children with diarrhea. Methodology. A cross-sectional study was conducted among 227 under-five children with diarrhea from July to October 2012 at Jimma town. Isolation and identification of Campylobacter species were performed using standard bacteriological techniques. Antimicrobial susceptibility test was performed following standard protocol. Chi-square and Fisher's exact tests were used for analysis. Results. From 227 under-five children, 16.7% were positive for Campylobacter spp.; isolates, C. jejuni, C. coli, and C. lari, accounted for 71.1%, 21.1%, and 7.9%, respectively. Higher rate of resistance was observed to ampicillin 76.3%, trimethoprim-sulfamethoxazole (68.4%), tetracycline (39.5%), chloramphenicol (31.6%), clindamycin (26.3%), and doxycycline (23.7%). Erythromycin, ciprofloxacin, gentamicin, norfloxacin, and nalidixic acid were effective for more than 80% of the isolates. Multiple drug resistance was observed among 78.9% of all the three spp. Conclusions. Isolation rate of Campylobacter spp. was high. C. lari was reported for the first time at this study area. Higher rate of resistance was observed to the commonly used drugs.
引言。弯曲杆菌是食源性疾病的主要细菌性病因之一。对抗菌药物耐药的弯曲杆菌属的流行率正在上升。本研究旨在确定五岁以下腹泻儿童中弯曲杆菌属的流行率及抗菌药物敏感性模式。方法。2012年7月至10月在吉马镇对227名五岁以下腹泻儿童进行了一项横断面研究。使用标准细菌学技术进行弯曲杆菌属的分离和鉴定。按照标准方案进行抗菌药物敏感性试验。采用卡方检验和费舍尔精确检验进行分析。结果。在227名五岁以下儿童中,16.7%的儿童弯曲杆菌属检测呈阳性;分离株中,空肠弯曲杆菌、大肠弯曲杆菌和海鸥弯曲杆菌分别占71.1%、21.1%和7.9%。观察到对氨苄西林的耐药率较高(76.3%)、甲氧苄啶 - 磺胺甲恶唑(68.4%)、四环素(39.5%)、氯霉素(31.6%)、克林霉素(26.3%)和强力霉素(23.7%)。红霉素、环丙沙星、庆大霉素、诺氟沙星和萘啶酸对超过80%的分离株有效。在所有三种弯曲杆菌属中,78.9%观察到多重耐药。结论。弯曲杆菌属的分离率较高。本研究区域首次报告了海鸥弯曲杆菌。观察到对常用药物的耐药率较高。
