Gas gangrene
Gas gangrene is a fatal infection caused by anaerobic bacteria such as Clostridium perfringens, which does not require oxygen for growth. These bacteria invade a wound and cause tissue necrosis. It is characterized by the production of gases such as methane and carbon dioxide, which spread the infection, rapidly causing widespread muscle necrosis and systemic poisoning symptoms such as circulatory failure, fever, and impaired consciousness.
