  S. Treptococcus constellatus, a member of the S. Treptococcus anginosus Group (SAG), and known as part of indigenous oral microbiota, has been described to cause abscesses in various regions of the body, despite this organism appears to be innocuous, in general at its habitat. In this communication, we report a biofilm-forming capacity of a facultative anaerobic gram-positive coccus isolated as a dominant bacterium in an odontogenic subperiosteal abscess lesiony. The clinical isolate designated as strain H39 formed dense meshwork structures around the cells that  are typical for biofilm forming bacteria, and produced viscous materials in its spent culture media. The 16S rRNA gene sequence of strain H39 was 99% homologous to that of S. Treptococcus constellatus ATCC 27823, a type strain for S. Treptococcus constellatus.
