Gas gangrene is caused by all, EXCEPT:
Correct Answer: CI. sporogenes
Description: Gas gangrene or clostridial myonecrosis is produced by any one of several clostridia (Clostridium perfringens, C ramosum, C bifermentans, C histolyticum, C novyi, etc). Trauma and injection drug use are common predisposing conditions. Toxins produced into devitalized tissues under anaerobic conditions result in shock, hemolysis, and myonecrosis. Gas gangrene usually begins 1 to 4 days after the injury but may sta within 10 hours. The earliest repoed finding is severe pain at the site of the wound accompanied by a sense of heaviness or pressure. The disease then progresses rapidly with edema, tenderness, and pallor, followed by discoloration and hemorrhagic bullae. The gas is apparent as crepitus in the tissue, but this is a late sign.
