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 a non-communicable disease. It does not spread from person to person. There are different types of gangrene with different symptoms, such as dry gangrene, wet gangrene, gas gangrene, internal gangrene and necrotizing fasciitis.he etymology of gangrene derives from the Latin word gangraena and from the Greek gangraina (Î³Î¬Î³Î³ÏÎ±Î¹Î½Î±), which means  putrefaction of tissues. It has no etymological connection with the word green, despite the affected areas turning black and/or green and/or yellowish brown.
