金黄色葡萄球菌是一种重要病原微生物,广泛存在于奶牛乳腺感染中,特别是乳房炎。随着抗生素广泛使用,金黄色葡萄球菌产生多药耐药性（MDR）能力受到研究者极大关注。特别是从牛中分离菌株对常规抗生素耐药性出现惊人增长,对奶牛健康、乳制品安全造成严重威胁。本文探讨奶牛源多重耐药金黄色葡萄球菌耐药机制,分析其流行病学、耐药机制及防控策略,为保障奶牛健康、乳品安全奠定基础。
Staphylococcus aureus is an important pathogenic microorganism,which widely exists in the mammary gland infection of dairy cows,especially mastitis.With the widespread use of antibiotics,Staphylococcus aureus has shown the ability to produce multidrug-resistant（MDR）,which has attracted great attention from researchers. In particular,the mechanism of strains isolated from cattle to conventional antibiotics has increased dramatically,which poses a serious threat to the health of dairy cows and the safety of dairy products. The purpose of this paper is to explore the drug mechanism characteristics of multidrug-resistant Staphylococcus aureus of dairy cows,analyze its epidemiology,drug mechanism and prevention and control strategies,and lay a foundation for ensuring the health of dairy cows and the safety of dairy products.
