A total of 168 coagulase-negative staphylococci (CNS) strains were isolated from milk samples taken from cows with clinical mastitis. The samples were collected between January 1990 and August 1992 from cows in the veterinary surveillance area of the Ambulatory Clinic, College of Veterinary Medicine, Hautjärvi, Finland. In 100 cases the effect of antibiotic treatment was evaluated 3-4 weeks after initial sampling. Clinical symptoms of the animals were recorded, and the inflammatory status of their udders was evaluated using the CMT test and assessing milk NAGase activity. CNS mastitis was most common in young cows during early lactation. Staphylococcus hyicus, S. simulans and S. epidermidis were the most frequently isolated CNS. Clinical symptoms were most severe with S. hyicus. Cure rates for CNS induced mastitis were high.
从患有临床型乳腺炎的奶牛所采集的牛奶样本中，共分离出168株凝固酶阴性葡萄球菌（CNS）。这些样本于1990年1月至1992年8月期间，从芬兰豪蒂耶尔维兽医学院门诊诊所兽医监测区域的奶牛身上采集。在100例病例中，在初次采样3 - 4周后评估抗生素治疗效果。记录动物的临床症状，并使用CMT试验和评估牛奶N - 乙酰 - β - 氨基葡萄糖苷酶（NAGase）活性来评估其乳房的炎症状态。CNS乳腺炎在初产早期的年轻奶牛中最为常见。猪葡萄球菌、模仿葡萄球菌和表皮葡萄球菌是最常分离出的CNS。猪葡萄球菌引起的临床症状最为严重。CNS引起的乳腺炎治愈率很高。
