gas gangrene toxin

gas gangrene toxin
any of the exotoxins produced by Clostridium perfringens and associated with gas gangrene. At least 10 types have been identified. The α toxin is a lethal, necrotizing lecithinase (phospholipase-C) that splits lecithin in cell membranes, is hemolytic, and causes capillary damage. C. novyi and C. septicum produce similar toxins that cause gas gangrene.
