Gas Gangrene

Abstract
THE etiologic agents of gas gangrene (genus clostridium) are large gram-positive anaerobic rods that possess a central or subterminal spore. Six species (Clostridium perfringens, C. novyi [oedematiens], C. septicum, C. histolyticum, C. bifermentans and C. fallax) cause gas gangrene in man. Individual lesions often yield more than one species; C. perfringens is the one most commonly recovered (80 per cent), and next in frequency are C. novyi (40 per cent) and C. septicum (20 per cent).1 , 2 All require nearly complete anaerobiosis and a low redox potential for growth. Clostridia are saprophytes; both the vegetative and spore forms are . . .
