To evaluate the prevalence of multidrug resistant Staphylococcus aureus (S. aureus) in dairy products.
Isolation and identification of S. aureus were performed in 3 dairy-based food products. The isolates were tested for their susceptibility to 5 different common antimicrobial drugs.
Of 50 samples examined, 5 (10%) were contaminated with S. aureus. Subsequently, the 5 isolates were subjected to antimicrobial resistance pattern using five antibiotic discs (methicillin, vancomycin, kanamycin, chloramphenicol and tetracycline). Sample 29 showed resistance to methicillin and vancomycin. Sample 18 showed intermediate response to tetracycline. The other samples were susceptible to all the antibiotics tested.
The results provide preliminary data on sources of food contamination which may act as vehicles for the transmission of antimicrobial-resistant Staphylococcus. Therefore, it enables us to develop preventive strategies to avoid the emergence of new strains of resistant S. aureus.
评估乳制品中耐多药金黄色葡萄球菌（S. aureus）的流行情况。
对3种乳制品进行金黄色葡萄球菌的分离和鉴定。对分离株进行5种不同常用抗菌药物的敏感性测试。
在50份检测样本中，5份（10%）被金黄色葡萄球菌污染。随后，使用5种抗生素药敏纸片（甲氧西林、万古霉素、卡那霉素、氯霉素和四环素）对这5株分离株进行耐药模式检测。样本29对甲氧西林和万古霉素耐药。样本18对四环素呈中度反应。其他样本对所有测试抗生素敏感。
研究结果提供了关于食品污染来源的初步数据，这些污染来源可能是耐抗菌药物金黄色葡萄球菌传播的载体。因此，有助于我们制定预防策略，以避免新的耐甲氧西林金黄色葡萄球菌菌株出现。
