Strains formerly identified as Streptococcus bovis were allotted to two groups by sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of whole-cell proteins. Strains from humans with infections, mostly patients with endocarditis, and strains from pigeons with septicemia clustered with the recently described species Streptococcus gallolyticus. The original S. bovis type strain and strains exclusively from ruminants formed the second cluster. The findings indicate that S. gallolyticus is more likely to be involved in human and animal infections than S. bovis. Growth characteristics and several biochemical reactions were found to be useful in the differentiation of S. gallolyticus from S. bovis.
通过对全细胞蛋白进行十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分析,先前鉴定为牛链球菌的菌株被分为两组。来自感染人类(主要是心内膜炎患者)的菌株以及来自患有败血症的鸽子的菌株,与最近描述的解脲链球菌属物种聚集在一起。原始的牛链球菌模式菌株和仅来自反刍动物的菌株形成了第二组。研究结果表明,与牛链球菌相比,解脲链球菌更有可能参与人类和动物感染。发现生长特性和一些生化反应有助于区分解脲链球菌和牛链球菌。
