RPS-mediated interbacterial adhesion promotes the growth of S. oralis 34 and A. naeslundii T14V as a biofilm in flowing human saliva. Flow cells were incubated overnight at 37C following inoculation with different combinations of wild type strain 34 or an RPS-negative mutant and wild type strain T14V or a type 2 fimbriae deficient mutant. Biofilms were labeled with conjugated antibodies to detect streptococci (red) and actinomyces (blue) and examined confocal fluorescent microscopy.
