has been found to be the major cause of foodborne diseases and a serious public health problem in the world, with an increasing concern for the emergence and spread of antimicrobial-resistant strains. A cross-sectional study was conducted between February 2014 and December 2015 on food items of animal origin to assess the prevalence and antimicrobial resistance profiles of isolates using standard bacteriological methods. The overall prevalence rate of 5.5% was recorded from the total analyzed food items of animal origin. isolates were detected from 12% of raw meat, 8% of minced meat, 2.9% of burger samples, 18% of raw eggs, and 6% of raw milk. Furthermore, antimicrobial susceptibility test identified 47.6% resistant isolates, 28.6% intermediately sensitive isolates, and 23.8% susceptible isolates. Among isolates tested, 42.6%, 28.6%, and 14.3% were found to be relatively resistant to tetracycline, sulfamethoxazole-trimethoprim, and ampicillin, respectively, while 9.5%-19% were intermediately resistant to tetracycline, amoxicillin, ampicillin, cephalothin, and nitrofurantoin. Therefore, our findings provide the prevalence and drug resistance of from foods of animal origin and contribute information to scientists as well as public health researchers to minimize the prevalent and resistant foodborne species in Ethiopia.
已被发现是食源性疾病的主要原因以及全球一个严重的公共卫生问题，人们对抗菌素耐药菌株的出现和传播日益关注。2014年2月至2015年12月期间，对动物源性食品进行了一项横断面研究，以使用标准细菌学方法评估分离株的流行情况和抗菌药物耐药性概况。在所有分析的动物源性食品中，总体流行率记录为5.5%。从12%的生肉、8%的碎肉、2.9%的汉堡样本、18%的生鸡蛋和6%的生牛奶中检测到分离株。此外，抗菌药物敏感性试验确定47.6%的分离株耐药，28.6%的分离株中度敏感，23.8%的分离株敏感。在测试的分离株中，分别发现42.6%、28.6%和14.3%对四环素、磺胺甲恶唑-甲氧苄啶和氨苄青霉素相对耐药，而9.5%-19%对四环素、阿莫西林、氨苄青霉素、头孢噻吩和呋喃妥因中度耐药。因此，我们的研究结果提供了动物源性食品中该菌的流行情况和耐药性，并为科学家以及公共卫生研究人员提供信息，以尽量减少埃塞俄比亚流行的和耐药的食源性病原体种类。
