Mucormycosis is a disease caused by a fungus from the Phycomycetes class and the Mucorales order. Phycomycetes are ubiquitous fungi occurring in soil, air, skin, body orifices, manure, and food. They are commonly seen in diabetics, particularly in patients with ketoacidosis.'" Numerous other predisposing conditions have been reported.2 36 Gas gangrene refers to a necrotising infection of the soft tissue caused by a Clostridium species. Clostridium perfringens is recovered in about 80% of cases. Other Clostridium species which commonly cause gas gangrene in humans are nozyi, septicum, and sordellii.7
