Background. Cockroaches are source of bacterial infections and this study was aimed to assess bacterial isolates and their antimicrobial profiles from cockroaches in Gondar town, Ethiopia. Methods. A total of 60 cockroaches were collected from March 1 to May 30, 2014, in Gondar town. Bacterial species were isolated from external and internal parts of cockroaches. Disk diffusion method was used to determine antibiotic susceptibility patterns. Data were entered and analyzed by using SPSS version 20; P values <0.005 were considered as statistically significant. Results. Of 181 identified bacteria species, 110 (60.8%) and 71 (39.2%) were identified from external and internal parts of cockroaches, respectively. Klebsiella pneumoniae 32 (17.7%), Escherichia coli 29 (16%), and Citrobacter spp. 27 (15%) were the predominant isolates. High resistance rate was observed to cotrimoxazole, 60 (33.1%), and least resistance rate was noted to ciprofloxacin, 2 (1.1%). Additionally, 116 (64.1%) of the isolates were MDR strains; Salmonella spp. were the leading MDR isolates (100%) followed by Enterobacter (90.5%) and Shigella spp. (76.9%). Conclusion. Cockroaches are the potential source of bacteria pathogens with multidrug resistant strains and hence effective preventive and control measures are required to minimize cockroach related infections.
背景。蟑螂是细菌感染的来源，本研究旨在评估埃塞俄比亚贡德尔镇蟑螂的细菌分离株及其抗菌谱。方法。2014年3月1日至5月30日期间，在贡德尔镇共收集了60只蟑螂。从蟑螂的外部和内部分离细菌种类。采用纸片扩散法测定抗生素敏感性模式。数据使用SPSS 20版录入和分析；P值<0.005被认为具有统计学意义。结果。在181种已鉴定的细菌种类中，分别从蟑螂的外部和内部鉴定出110种（60.8%）和71种（39.2%）。肺炎克雷伯菌32株（17.7%）、大肠杆菌29株（16%）和柠檬酸杆菌属27株（15%）是主要分离株。观察到对复方新诺明的耐药率较高，为60株（33.1%），对环丙沙星的耐药率最低，为2株（1.1%）。此外，116株（64.1%）分离株为多重耐药菌株；沙门氏菌属是主要的多重耐药分离株（100%），其次是肠杆菌属（90.5%）和志贺氏菌属（76.9%）。结论。蟑螂是具有多重耐药菌株的细菌病原体的潜在来源，因此需要采取有效的预防和控制措施，以尽量减少与蟑螂相关的感染。
