The oral pathogenPorphyromonas gingivalis expresses a homolog of the internalin family protein InlJ. Inactivation ofinlJ reduced monospecies biofilm formation byP. gingivalis . In contrast, heterotypicP. gingivalis -Streptococcus gordonii biofilm formation was enhanced in the InlJ-deficient mutant. The results indicate a nuanced role for InlJ in regulating biofilm accumulations ofP. gingivalis .
