Abstract
Nuclease was produced by 47 of the Staphylococcus epidermidis strains isolated from bovine quarter milk samples. The quantity of enzyme produced by different strains varied considerably. The nuclease of bovine S. epidermidis strains was heat-stable, the average D-value at 120°G being estimated to be 19 min. The nucleases of S. epidermidis and S. aureus could be identified, and consequently differentiated by serological methods. S. epidermidis was a less severe udder pathogen than S. aureus. However, no difference was observed in udder pathogenicity between S. epidermidis strains with low or high in vitro nuclease production.
摘要
从奶牛乳房乳样中分离出的47株表皮葡萄球菌产生了核酸酶。不同菌株产生的酶量差异很大。奶牛表皮葡萄球菌菌株的核酸酶具有热稳定性，在120℃下的平均D值估计为19分钟。表皮葡萄球菌和金黄色葡萄球菌的核酸酶可以通过血清学方法进行鉴定，从而加以区分。表皮葡萄球菌作为乳房病原体，其致病性不如金黄色葡萄球菌严重。然而，体外核酸酶产量低或高的表皮葡萄球菌菌株在乳房致病性方面未观察到差异。
