Spatial Distribution and Chemical Tolerance of Streptococcus mutans within Dual-Species Cariogenic Biofilms.


ABSTRACT: Bacterial interspecies interactions in the oral cavity influence the structural development of cariogenic biofilms and dental caries. Visualization of the biofilm architecture and bacterial localization within biofilms is essential for understanding bacterial interactions. We herein demonstrated that the spatial localization of Streptococcus mutans within dual-species biofilms was altered in a manner that depended on the partner. Furthermore, we found that these biofilms influenced the survival of S. mutans against disinfectants. The present results provide information on how S. mutans interact with other bacteria in multi-species cariogenic biofilms.
