APPLIED RADIOLOGICAL ANATOMY

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.

Detailed explanation-2: -Causes. Gas gangrene is most often caused by bacteria called Clostridium perfringens. It also can be caused by group A streptococcus, Staphylococcus aureus, and Vibrio vulnificus. Clostridium is found nearly everywhere.

Detailed explanation-3: -It is usually caused by traumatic injury; however spontaneous gas gangrene (SGG) is also reported, nearby always in patients with underlying diseases, especially gastrointestinal disease, and is typically caused by Clostridium septicum.

Detailed explanation-4: -Clostridium perfringens bacteria are one of the most common causes of food poisoning. CDC estimates that the bacterium causes nearly 1 million foodborne illnesses in the United States every year.

Detailed explanation-5: -Clostridium perfringens is an anaerobic Gram-positive spore-forming bacillus associated with acute gastrointestinal infections ranging in severity from diarrhea to necrotizing enterocolitis and myonecrosis in humans.
