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.
Other types (species) of Clostridium bacteria, such as Clostridium perfringes, can cause serious wound and surgical infections, such as gas gangrene. Surgeryâsurgical sites are most commonly infected with the person's normal skin and/or digestive tract flora, the same microbes seen with superficial infections.
