is well-known globally as one of the most significant foodborne bacterial pathogens. Listeriosis may trigger life-threatening illness, such as severe sepsis, meningitis, sometimes resulting in lifelong harm and even death. This study aimed to determine the occurrence and antibiotic resistance pattern of in red meats sold at retail outlets in Erbil city, Kurdistan region, Iraq. Three hundred and seventy-five (375) samples were aseptically collected from retail meat shops between July and December 2018 For isolation of , samples were cultured on selective media and tested for their susceptibility to common antibiotics by disk diffusion assay. The results revealed that the overall occurrence of in red meat samples was 13.9%. Warm season was associated with increase in occurrence. The results of antimicrobial susceptibility testing showed that 98.1%, 94.2%, and 82.7% of isolates were resistant to Streptomycin, Gentamicin, and Ampicillin respectively. This resistance pattern of is critically alarming owing to the aforementioned antibiotics are the drugs of choice of treatment of listeriosis. This level of resistance requires further investigations and effective countermeasures since it may pose a public health hazard.
作为最重要的食源性细菌病原体之一，在全球范围内广为人知。李斯特菌病可能引发危及生命的疾病，如严重败血症、脑膜炎，有时会导致终身伤害甚至死亡。本研究旨在确定伊拉克库尔德地区埃尔比勒市零售网点销售的红肉中该菌的发生率及抗生素耐药模式。2018年7月至12月期间，从零售肉店无菌采集了375份样本。为分离该菌，将样本接种在选择性培养基上，并通过纸片扩散法检测其对常用抗生素的敏感性。结果显示，红肉样本中该菌的总体发生率为13.9%。温暖季节与该菌发生率的增加有关。抗菌药敏试验结果表明，分别有98.1%、94.2%和82.7%的分离株对链霉素、庆大霉素和氨苄西林耐药。鉴于上述抗生素是治疗李斯特菌病的首选药物，该菌的这种耐药模式令人极为担忧。由于这种耐药水平可能对公众健康构成危害，因此需要进一步调查并采取有效对策。
