Gas gangrene is commonly caused by infection with the bacterium Clostridium perfringens, which develops in an injury or surgical wound that's depleted of blood supply. The bacterial infection produces toxins that release gas â hence the name gas gangrene â and cause tissue death.
Gangrene is death or damage of body tissue due to a loss of blood supply. Gangrene may be caused by reduced blood flow in the arteries, or it can result from a severe bacterial infection. Gangrene may affect any part of the body. One form of this condition, called Fournier's gangrene, affects the male genitalia. Gangrene is a medical emergency.
