李斯特菌病主要由单核细胞增生李斯特菌引起，由于其临床严重性和高死亡率，特别是在高危人群中，已成为公共卫生当局的主要关注点。目前，关于埃塞俄比亚贡达尔镇动物源性即食食品中寄生虫属物种的流行率和抗菌药物敏感性特征的信息有限。本研究的目的是确定李斯特菌的流行和抗菌药物敏感性模式，从即食食品的动物源性的公共餐饮场所在贡达尔镇，埃塞俄比亚。本研究对主要超市、肉店、糕点店、餐馆和酒店的动物源性即食食品进行了横断面研究。采用培养、生化和糖代谢试验对分离菌株进行菌种鉴定，并采用纸片扩散法对分离菌株进行药敏试验。在三百八十四个食物样本中，九十六个（百分之二十五）对李斯特菌呈阳性反应。24例（6.25%）检出单核细胞增生李斯特菌。从蛋糕、生肉、冰淇淋、碎牛肉、鱼、生牛乳和比萨饼中分离出单核细胞增生李斯特菌的比例从高到低依次为：L.的抗菌药物敏感性分析。单核细胞增多症显示存在四种多药耐药分离株。青霉素、萘啶酸、四环素、氯霉素的耐药率依次升高。阿尔湖在当前研究中鉴定的单核细胞增多症对阿莫西林、头孢噻吩、氯唑西林、磺胺甲恶唑、庆大霉素和万古霉素敏感。L的存在。在一些即食食品中检测到的单核细胞增多症菌株，包括抗药性和多重抗药性菌株，是对消费者，特别是高危人群的公共卫生存在危害的指标。因此，强烈建议提高对食品安全的认识，并实施关于人类和动物使用药物的法规。本文的在线版本（doi：10.1186/s12866-015-0434-4）包含补充材料，可供授权用户使用。
Listeriosis, mostly caused by Listeria monocytogenes species, has become a major concern to public health authorities due to its clinical severity and high mortality rate, particularly in high risk groups. Currently, there is limited information regarding the prevalence and antimicrobial susceptibility profiles of listeria species in ready-to-eat foods of animal origin in Gondar town, Ethiopia. The aim of this study was to determine the prevalence and antimicrobial susceptibility pattern of Listeria species isolated from ready-to-eat food of animal origin from public dinning places in Gondar town, Ethiopia. A cross sectional study on ready-toeat foods of animal origin sampled from major supermarkets, butcher shops, pastry shops, restaurants and hotels was carried out. Culture, biochemical and sugar tests were conducted for listeria species identification and disc diffusion test was performed to study the antimicrobial susceptibility profiles of the isolates. Out of 384 food samples examined, 96 (25%) were positive for Listeria species. Listeria monocytogenes was detected in 24 (6.25%) of the samples. Listeria monocytogenes was isolated from cake, raw meat, ice cream, minced beef, fish, unpasteurized milk and pizza in that order from higher to lower rate. Assessment of antimicrobial susceptibility profile of L. monocytogenes revealed the presence of four multi-drug resistant isolates. The higher resistance rate was recorded for penicillin, nalidixic acid, tetracycline and chloramphenicol, in decreasing order. All L. monocytogenes identified in the current study were sensitive to amoxicillin, cephalothin, cloxacillin, sulfamethoxazole, gentamicin and vancomycin. The presence of L. monocytogenes including drug resistant and multidrug resistant isolates in some ready-to-eat food items is an indicator of the presence of public health hazards to the consumer, particularly to the high-risk groups. Hence awareness creation on food safety and implementation of regulations about the use of drugs in humans and animals is strongly recommended.
