Gangrene
Definition
Types of gangrene
Dry gangrene Dry gangrene represents an area of coagulation necrosis resulting from infarction followed by mummification. The extremities of the body like tail, ears, legs and udder are affected.
Moist gangrene
Gas gangrene Anaerobic bacterial proliferation producing toxin and damaging the tissues. Examples: Clostridium perfringens, Clostridium septicum introduced by penetrating wounds. The clostridia proliferate in necrotic tissue under anaerobic environment and produce toxins which cause tissue damage. The Clostridia chauvoei spreads haematogenously from the intestine and lodges in muscle which requires some injury and necrosis for the spores to germinate and bacteria to proliferate.
