Abstract

Actinomyces viscosus, growing on a tooth in the presence of sucrose, slowly produced a loosely-attached plaque, the pH being 6.1 after 120 h. When the tooth was inoculated simultaneously with A. viscosus and either Streptococcus sanguis or Streptococcus mutans, firmly-adherent plaque was quickly formed and the pH fell below 5 after 33 h with the former Streptococcus and 24 h with the latter. A. viscosus disappeared from each mixed plaque by 120 h.

摘要

粘性放线菌在有蔗糖存在的情况下在牙齿上生长，会缓慢产生一种附着松散的菌斑，120小时后pH值为6.1。当牙齿同时接种粘性放线菌和血链球菌或变形链球菌时，会迅速形成牢固附着的菌斑，与前者链球菌一起培养33小时后pH值降至5以下，与后者一起培养24小时后pH值降至5以下。到120小时时，粘性放线菌从每个混合菌斑中消失。
