变形链球菌(下称变链菌)和粘性放线菌(下称粘放菌)是人牙菌斑中的主要细菌成分。体内外实验表明,这两种细菌均能利用多种碳水化合物生长产酸,造成龋损。 作者将含3％葡萄糖的液体培养基分3组,1、2组分别接种变链菌和粘放菌悬液,3组接种两菌混合菌液.

Streptococcus mutans (Streptococcus mutans) and actinomycetes sticky (hereinafter referred to as bacteria) are the main bacterial components in human plaque. In vitro and in vivo experiments show that both bacteria can utilize a variety of carbohydrates to produce acid, resulting in carious lesions. The authors divided the liquid medium containing 3% glucose into 3 groups, 1, 2 groups were inoculated with Streptococcus mutans and inoculation bacterial suspension, 3 groups were inoculated with two bacteria mixed liquid.
