Mutans streptococci (Streptococcus mutans and Streptococcus sobrinus) exhibited low levels of proteolytic activity against the model protein substrate, FITC-labelled bovine serum albumin, when incubated alone. Inclusion of other members of the dental plaque microflora in the assay usually resulted in marked increases in the degree of proteolysis and a high level of synergy. Interactions between mutans streptococci and either Streptococcus oralis or Fusobacterium nucleatum gave rise to the greatest degree of synergistic proteolytic degradation.
