The oral streptococci have undergone considerable taxonomic revision in recent years but there is still little information concerning associations between the newly defined species and disease. This study examined the identities of 47 strains of oral streptococci collected from 42 confirmed cases of infective endocarditis. By means of recently described physiological schemes, the most common species identified were Streptococcus sanguis sensu stricto (31.9%), S. oralis (29.8%) and S. gordonii (12.7%). Other related species including S. mitis and "S. parasanguis" were less common. This indicates that attention should be focused on S. sanguis sensu stricto and S. oralis when considering possible pathogenic mechanisms involved in viridans streptococcal endocarditis.
近年来，口腔链球菌的分类学经历了重大修订，但关于新定义的菌种与疾病之间的关联，仍知之甚少。本研究检测了从42例确诊感染性心内膜炎病例中分离出的47株口腔链球菌的菌种特性。根据最近描述的生理学分类方法，最常见的菌种为血链球菌（狭义）（31.9%）、口腔链球菌（29.8%）和戈登链球菌（12.7%）。其他相关菌种，包括缓症链球菌和“副血链球菌”则较为少见。这表明，在考虑草绿色链球菌性心内膜炎可能的致病机制时，应将重点放在血链球菌（狭义）和口腔链球菌上。
