The prevalence of staphylococcal species isolated from bovine mammary glands was determined in four dairy herds. Staphylococcus aureus and S hyicus were the predominant organisms isolated from cows in a herd with a bulk milk somatic cell count (SCC) greater than 900 X 10(3). One herd with a bulk milk SCC of 565 X 10(3) had a high incidence of S aureus while the predominant coagulase-negative species were S epidermidis and S hyicus. S hyicus predominated in two herds with bulk milk SCC less than 200 X 10(3); prevalence of S aureus was low. The impact of herd management practices such as post-milking teat antisepsis on distribution of staphylococcal species is discussed.
在四个奶牛场中测定了从牛乳腺分离出的葡萄球菌种类的流行情况。在一个批量牛奶体细胞计数（SCC）大于900×10³的牛群中，金黄色葡萄球菌和猪葡萄球菌是从奶牛中分离出的主要微生物。一个批量牛奶SCC为565×10³的牛群中，金黄色葡萄球菌的发生率很高，而主要的凝固酶阴性菌种是表皮葡萄球菌和猪葡萄球菌。猪葡萄球菌在两个批量牛奶SCC小于200×10³的牛群中占主导；金黄色葡萄球菌的流行率很低。本文讨论了诸如挤奶后乳头消毒等牛群管理措施对葡萄球菌种类分布的影响。
