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