Abstract
A. 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 S. sanguis or S. mutans, firmly-adherent plaque was quickly formed and the pH fell below 5 after 33 h with the former and 24 h with the latter. A. viscosus disappeared from each mixed plaque by 120 h.
