Answer

Four bacteria causing gas gangrene (clostridial myonecrosis):

1. Clostridium perfringens — the most common causative organism.
2. Clostridium septicum.
3. Clostridium novyi.
4. Clostridium histolyticum.

(All are anaerobic, spore-forming, Gram-positive bacilli producing potent tissue-destructive exotoxins — e.g., C. perfringens alpha-toxin — causing rapid muscle necrosis with characteristic gas production, typically following deep, contaminated traumatic wounds.)
