Abstract

Porphyromonas gingivalis no. 381 and ATCC 33277 produced an extracellular hemolytic toxin which was heat-labile, trypsin-sensitive, and lytic to human, horse, sheep and rabbit erythrocytes. The hemolytic toxin is a 'hot-cold', thiol-independent toxin. The production of the hemolytic toxin was greatly enhanced by addition of hemoglobin to the culture medium.
