本研究对变形链球菌属各基因遗传种的产酸能力进行分析,发现变链菌属中的遗传Ⅰ型和Ⅲ型即变形链球菌(S.mutans)和茸毛链球菌(S.sobrinus)菌种具有较高的产酸及耐酸性。对茸毛链球菌的高致龋性,应予以足够的认识和重视。
In this study, we analyzed the acidogenic capacity of each genus of Streptococcus mutans and found that the genotypes I and III of S. mutans were S. mutans and S. sobrinus Species with high acid and acid. The highly cariogenic Streptococcus soils should be adequately recognized and valued.
