对40例健康足月婴儿口腔分离的367株先锋链球菌进行了生化和生理特性、Ig A1蛋白水解酶和糖苷酶活性两种分类方案的鉴定。从新生儿分离的链球菌中，口腔链球菌占55.0%。唾液链球菌占25.3%，绞股链霉菌、米氏链球菌、血链球菌和戈登链球菌分别占11.4%。在鉴定链球菌方面遇到了困难，367个分离物中有8.4%无法归类于公认的物种。
Three hundred and sixty-seven strains of pioneer streptococci isolated from the mouths of 40 healthy, full-term infants during the first month of life were examined by two taxonomic schemes that incorporated biochemical and physiological characteristics, IgA1 protease production and glycosidase activities. Streptococcus mitis biovar 1 and S. oralis comprised 55.0% of the pioneer streptococci isolated from neonates. S. salivarius constituted 25.3% of the isolates, while S. anginosus, S. mitis biovar 2, S. sanguis and S. gordonii accounted collectively for 11.4%. Difficulties in identifying streptococci were encountered and 8.4% of the 367 isolates could not be assigned to a recognised species.
