WebJan 2, 2024 · Clostridium perfringens can produce a significant amount of protein toxins, particularly alpha toxin (the primary pathogenic indicator of hemolysis and gas gangrene). One toxin is phospholipase C lecithinase, which in the membranes of red blood cells, induces hydrolysis of phospholipids, thereby resulting in intravascular hemolysis. WebVirulence factors Common toxins produced by C. perfringens: Alpha toxin: Lecithinase (or phospholipase) that breaks down cell membrane resulting in cell death and tissue necrosis. This toxin is also hemolytic and cardiotoxic. Beta toxin: Necrosis of tissue Delta toxin: Hemolysin Epsilon toxin: Acts to increase cell membrane permeability; permease.
