Oxygen is carried in the blood, binding to the haemoglobin in our red blood cells to reach tissues all across our body, to keep them alive and functioning properly. However, when blood flow to these tissues is decreased or lost altogether, which can arise through thrombosis (hardening of the arteries) these tissues are exposed to less oxygen and the cells which they consist of start to die. When cells start to die, they began to leak autolytic enzymes which make it impossible for them to be repaired naturally. Gangrene can also develop as a result of bacterial infections in congealed blood; this type of gangrene is known as wet gangrene. Similarly, another type, dry gangrene is caused by bacterial but is the result of swelling due. In the United States, the bacteria Clostridium perfringens is the most common cause of another type, gas gangrene1. Simple bites can also lead to necrosis, such as the bite in Figure A, below.

People who develop gangrene due to a bacterial infection have a higher incidence of death than those who develop it due to other factors, such as cardiovascular diseases, this is down to the fact that bacteria is able to reproduce very rapidly in the individuals body, leading to gangrene developing until enough of the body is compromised for it to become fatal. This difference in mortality is highlighted by the fact that gas gangrene has a 100% mortality if not treated. Why…
