Abstract
Porphyromonas gingivalis in which the synthesis of superoxide dismutase (SOD) was induced by nitrate or by aeration was rendered resistant to killing by polymorphonuclear leukocytes. SOD purified from either anaerobically maintained or aerated cells also inhibited bacterial killing when added exogenously, and no difference between the effects of the two SODs was observed. These results suggest that SOD may form part of a defense mechanism that helps protect P. gingivalis against killing by polymorphonuclear leukocytes.Entities:
