| 摘 要： | 为研究金黄色葡萄球菌(S.aureus)的因型特征,本实验利用聚合酶链式反(PCR)方法,对S.aureus的3个标准株和30个临床分离株的凝集因子A、凝固酶、溶血素等33种致病因子进行了检测.结果表明各分离株在毒力因子方面存在一定差异.这些差异的检测将为进一步研究S.aureus的致病性和有效防治提供参考. |

| Abstract: | The present study was carried out to genotypically characterize Staphylococcus aureus strains isolated from bovine mastitis cases. A total of 33 S. Aureus strains were characterized by polymerase chain reaction (PCR) using primers that amplify 31 genes encoding coagulase (coa), clumping factor (clfA), hemolysin, capsular polysaccharides (CP), and other virulence factors. The findings of the present studies would provide better understanding of the distribution of the prevalent S. Aureus clones among bovine mastiffs isolates, therefore aid in the development control measures against S. Aureus infections in dairy herds. |
