Abstract

The degree of binding was determined between DNA preparations from 65 staphylococci representing cluster defined in a numerical phenetic survey and 3H-labelled DNA from reference strains of S. epidermidis, S. haemolyticus, S. hominis, S. saprophyticus and S. warneri. The congruence between the DNA pairing and numerical phenetic data was good with S. epidermidis and S. saprophyticus being shown to be genomic species. However, some strains identified as S. epidermidis using recommended diagnostic procedures were found to belong to other taxa, notably S. simulans and S. warneri. The moles percent guanine plus cytosine content of the DNA of the test strains was within the range 27 to 34.

摘要

在一项数量分类学调查中，测定了代表不同菌群的65株葡萄球菌的DNA制剂与表皮葡萄球菌、溶血葡萄球菌、人葡萄球菌、腐生葡萄球菌和沃氏葡萄球菌参考菌株的3H标记DNA之间的结合程度。DNA配对与数量分类学数据之间的一致性在表皮葡萄球菌和腐生葡萄球菌中表现良好，表明它们是基因组种。然而，使用推荐的诊断程序鉴定为表皮葡萄球菌的一些菌株被发现属于其他分类群，尤其是模仿葡萄球菌和沃氏葡萄球菌。测试菌株DNA的鸟嘌呤加胞嘧啶摩尔百分比在27%至34%的范围内。
