Detailed explanation-1: -Gas gangrene is a highly lethal infection of soft tissue, caused by Clostridium species, with Clostridium perfringens being the most common. This is synonymous with myonecrosis and is characterized by rapidly progressive gangrene of the injured tissue along with the production of foul-smelling gas.
