Abstract

Two major subspecies of Staphylococcus cohnii, namely S. cohnii subsp. cohnii, from humans, and S. cohnii subsp. urealyticum, from humans and other primates, are described on the basis of a study of 14 to 25 strains and 18 to 33 strains, respectively. DNA-DNA hybridization studies conducted in our laboratory in 1983 (W. E. Kloos and J. F. Wolfshohl, Curr. Microbiol. 8:115-121, 1983) demonstrated that strains representing the different subspecies were significantly divergent. S. cohnii subsp. urealyticum can be distinguished from S. cohnii subsp. cohnii on the basis of its greater colony size; pigmentation; positive urease, beta-glucuronidase, and beta-galactosidase activities; delayed alkaline phosphatase activity; ability to produce acid aerobically from alpha-lactose; and fatty acid profile. The type strain of S. cohnii subsp. cohnii is ATCC 29974, the designated type strain of S. cohnii Schleifer and Kloos 1975b, 55. The type strain of S. cohnii subsp. urealyticum is ATCC 49330.

摘要

根据分别对14至25株菌株和18至33株菌株的研究，描述了科氏葡萄球菌的两个主要亚种，即来自人类的科氏葡萄球菌科氏亚种，以及来自人类和其他灵长类动物的科氏葡萄球菌解脲亚种。1983年在我们实验室进行的DNA - DNA杂交研究（W. E. 克洛斯和J. F. 沃尔夫肖尔，《当前微生物学》8:115 - 121，1983）表明，代表不同亚种的菌株有显著差异。科氏葡萄球菌解脲亚种可根据其更大的菌落大小、色素沉着、脲酶、β - 葡萄糖醛酸酶和β - 半乳糖苷酶活性呈阳性、碱性磷酸酶活性延迟、需氧条件下从α - 乳糖产酸的能力以及脂肪酸谱与科氏葡萄球菌科氏亚种区分开来。科氏葡萄球菌科氏亚种的模式菌株是ATCC 29974，即1975年施莱费尔和克洛斯指定的科氏葡萄球菌模式菌株55。科氏葡萄球菌解脲亚种的模式菌株是ATCC 49330。
