Abstract

An atypical Staphylococcus aureus (S. aureus) strain, isolated in a dairy herd over an 8 month period, was examined. The S. aureus strain was clumping factor negative, weakly heat-resistant deoxyribonuclease positive and produced narrow zones of double haemolysis. In total, 57 quarter infections were observed. Prevalence data per month, calculated as the percentage of quarters infected with this atypical S. aureus strain varied from 7.5% to 17.7% and the new infection rate varied from 0.14 to 0.55. In routine bacteriology, the large number of quarters infected with the atypical S. aureus could easily be misclassified as quarters infected with non-aureus staphylococci.

摘要

对一株在一个奶牛场8个月期间分离出的非典型金黄色葡萄球菌菌株进行了检测。该金黄色葡萄球菌菌株凝固因子阴性，耐热性脱氧核糖核酸酶弱阳性，且产生狭窄的双溶血环。总共观察到57个乳房感染病例。每月的患病率数据（以感染该非典型金黄色葡萄球菌菌株的乳房百分比计算）在7.5%至17.7%之间，新感染率在0.14至0.55之间。在常规细菌学中，大量感染非典型金黄色葡萄球菌的乳房很容易被误分类为感染非金黄色葡萄球菌的乳房。
