Plaque formation in vitro by Actinomyces viscosus in the presence of Streptococcus sanguis or Streptococcus mutans

Microbios

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.

Actinomycosis

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.
