Gangrene
Death and decay of body tissue (often of a limb) due to bacterial action; the affected part gradually turns black and causes blood poisoning.
Gangrene sets in as a result of loss of blood supply to the area. This may be due to disease (diabetes, atherosclerosis), an obstruction of a major blood vessel (as in thrombosis), injury, or frostbite. Bacteria colonize the site unopposed, and a strong risk of blood poisoning often leads to surgical removal of the tissue or the affected part (amputation).
