Characterization of T cell responses to the RgpA-Kgp proteinase-adhesin complexes of Porphyromonas gingivalis in BALB/c mice.

Porphyromonas gingivalis is a Gram-negative bacterium strongly associated with chronic periodontitis, an inflammatory oral disease. A major virulence factor common to all characterized strains of P. gingivalis is the RgpA-Kgp proteinase-adhesin complexes (RgpA-Kgp complexes).

Vaccination with recombinant adhesins from the RgpA-Kgp proteinase-adhesin complex protects against Porphyromonas gingivalis infection.

Porphyromonas gingivalis is a pathogen associated with chronic periodontitis, an inflammatory disease of the supporting tissues of the teeth. A major virulence factor for P. gingivalis is the RgpA-Kgp proteinase-adhesin complex.
