Stimulation of growth of <i>Porphyromonas gingivalis</i> by cell extracts from <i>Tannerella forsythia</i>

Abstract

A product or a component of T. forsythia seemed to stimulate growth of P. gingivalis under nutrition-limited conditions. Gingipains are considered to play an important role in digestion or uptake of this growth-promoting factor. The interaction between T. forsythia and P. gingivalis in growth may be in part related with the synergistic virulence in a murine model.
