Four species of oral streptococci were examined for their ability to grow in a complex medium supplemented with NaF, and at various pH levels. Streptococcus mutans strains were the most susceptible to inhibition, with Streptococcus mitior and Streptococcus sanguis being the least affected. The S. mutans genotype comprising serotypes c, e and f was more susceptible to inhibition by fluoride than was the genotype comprising serotypes d and g. The results suggest that the fluoride concentration of dental plaque might influence the relative proportions of the species of streptococci found in dental plaque.
对四种口腔链球菌在添加氟化钠的复合培养基中以及在不同pH水平下的生长能力进行了检测。变形链球菌菌株最易受到抑制，而轻链球菌和血链球菌受影响最小。与包含血清型d和g的基因型相比，包含血清型c、e和f的变形链球菌基因型对氟化物抑制更敏感。结果表明，牙菌斑中的氟化物浓度可能会影响牙菌斑中发现的链球菌种类的相对比例。
