摘要

采用数值分类学方法对从牛前乳样品中分离得到的300株分离菌株进行了分组。按相似度聚类得到19个类群;其中,有8个小组的成员超过9人。其余11组共分离38株。所有19个组在75%相似水平上连接,其中17个组在85%相似水平上连接。结果表明,除16株外,其余均为葡萄球菌属。它们可能属于一个物种(金黄色葡萄球菌),或者至少属于密切相关的物种。除17株外,其余均为过氧化氢酶阳性。各组间差异最大的是碳水化合物利用率、显色性、明胶酶产量。在0和7摄氏度以及15%的盐中生长。

Classification by Numerical Taxonomy of Staphylococci Isolated From the Bovine Udder
Three hundred and three isolates obtained from plating bovine foremilk samples on Baird-Parker Agar were grouped using numerical taxonomy. Clustering of the isolates according to their percent similarity resulted in 19 groups; of these, eight groups contained over nine members. The other 11 groups contained 38 isolates. All 19 groups were joined at the 75% similarity level, with 17 of the groups being joined above the 85% similarity level. Results indicate that all but 16 of the isolates belonged to the same genus (Staphylococcus). and they probably belonged to one species (Staphylococcus aureus) or at least to closely related species. All but 17 isolates were catalase-positive. The greatest variations among the groups were in utilization of carbohydrates, chromogenesis, gelatinase production. and growth at 0 and 7 C and in 15% salt.
