Outline of Final Research Achievements |
Ora biofilm cause dental caries and periodotal disease. Streptcoccus and Veillonella are known to have important roles in the biofilm formation at aerly stage.This study demonstrated the following results. 1. Auto inducer from V. tobetsuensis inhibited biofilm formation of S. gordonii. 2. Draft genome of V. tobetsuensis was revealed. 3. New method for identification of all veillonella species was established. 4. Based on metagenome analysis of saliva, it was demonstrated that Streptococcus species incresed in good oral hygiene, but Veillonella species incresde in poor ora hygiene. 5. Many unknown Veillonella species inhabited in oral cavities with poor oral hygiene.
