Overview 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 — hence the name gas gangrene — and cause tissue death.

Gangrene Growing only without the presence of oxygen, Clostridia are the main etiologic agents of gas gangrene. They invade wounds and injuries with diminished blood supply, release gas-producing toxins and ultimately cause gangrene of muscles and organs. [5, 8] The affected skin may appear grayish to purplish red in hue.

- Medical Definition of Gangrene. Gangrene: Tissue death due to loss of adequate blood supply. Sometimes bacteria invade such tissue and accelerate its decay. Dry gangrene is the death of tissue due to vascular insufficiency without bacterial invasion in which the tissue dies, loses sensation and simply dries up, blackens, and shrivels. Dry gangrene eventually requires amputation.

Gangrene There are three major types of gangrene: dry, moist, and gas (a type of moist gangrene). Dry gangrene is a condition that results when one or more arteries become obstructed.

Anaerobic Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it. Infections like tetanus and gangrene are caused by anaerobic bacteria. Anaerobic infections typically cause abscesses (buildups of pus), and death of tissue. Many anaerobic bacteria produce enzymes that destroy tissue and, sometimes, potent toxins. Besides bacteria, some protozoans and worms are also anaerobic.

Gangrene The diagnosis of gangrene is based on history, physical examination, blood tests, and other exams. The health-care provider asks the person about any history of injury, chronic diseases (such as diabetes), surgery, cigarette smoking, and exposure to extreme cold. Physical examination of the affected area is performed to look for signs of gangrene. Blood test results show an increase in the number of white blood cells in persons with wet gangrene or infection. A sample of the drainage from the wound is examined to identify the bacteria causing the infection.
