长期以来,口腔链球菌的分类和命名比较混乱,在国际上尚缺乏统一的意见。随着分类新技术的发展,特别是细菌遗传学的研究,进一步澄清了细菌间的种系发生关系,一些原来的分类和命名被修正,同时分出了一些新菌种。本文就近年来口腔链球菌分类和命名的进展作一综述。 For a long time, the classification and nomenclature of Streptococcus oralis is quite confused, and there is still no unified opinion in the world. With the development of new classification technologies, especially the study of bacterial genetics, the phylogenetic relationships among bacteria were further clarified. Some of the original classification and nomenclature were revised and some new species were separated. This article reviews the recent progress in the classification and nomenclature of Streptococcus oralis.
