Abstract

Salmonellosis is one of the major food-borne diseases in many countries. This study was carried out to determine the occurrence of Salmonella spp., Salmonella Enteritidis, and Salmonella Typhimurium in raw chicken meat from wet markets and hypermarkets in Selangor, as well as to determine the antibiotic susceptibility profile of S. Enteritidis and S. Typhimurium. The most probable number (MPN) in combination with multiplex polymerase chain reaction (mPCR) method was used to quantify the Salmonella spp., S. Enteritidis, and S. Typhimurium in the samples. The occurrence of Salmonella spp., S. Enteritidis, and S. Typhimurium in 120 chicken meat samples were 20.80%, 6.70%, and 2.50%, respectively with estimated quantity varying from <3 to 15 MPN/g. The antibiogram testing revealed differential multi-drug resistance among S. Enteritidis and S. Typhimurium isolates. All the isolates were resistance to erythromycin, penicillin, and vancomycin whereas sensitivity was recorded for Amoxicillin/Clavulanic acid, Gentamicin, Tetracycline, and Trimethoprim. Our findings demonstrated that the retail chicken meat could be a source of multiple antimicrobial-resistance Salmonella and may constitute a public health concern in Malaysia.

摘要

沙门氏菌病是许多国家主要的食源性疾病之一。本研究旨在确定马来西亚雪兰莪州湿货市场和大型超市的生鸡肉中沙门氏菌属、肠炎沙门氏菌和鼠伤寒沙门氏菌的存在情况,并确定肠炎沙门氏菌和鼠伤寒沙门氏菌的抗生素敏感性谱。采用最大可能数(MPN)结合多重聚合酶链反应(mPCR)方法对样本中的沙门氏菌属、肠炎沙门氏菌和鼠伤寒沙门氏菌进行定量。120份鸡肉样本中沙门氏菌属、肠炎沙门氏菌和鼠伤寒沙门氏菌的检出率分别为20.80%、6.70%和2.50%,估计数量在<3至15 MPN/g之间。抗菌谱测试显示肠炎沙门氏菌和鼠伤寒沙门氏菌分离株之间存在不同的多重耐药性。所有分离株对红霉素、青霉素和万古霉素耐药,而对阿莫西林/克拉维酸、庆大霉素、四环素和甲氧苄啶敏感。我们的研究结果表明,零售鸡肉可能是多重耐药性沙门氏菌的一个来源,可能构成马来西亚的公共卫生问题。
