Answer

- [x] a) Clostridium perfringens

Clostridium perfringens is the most common cause of gas gangrene (clostridial myonecrosis), producing alpha-toxin (a lecithinase) and other tissue-destructive toxins/enzymes that cause rapid muscle necrosis with gas production, typically following deep, contaminated (often traumatic) wounds. Clostridium tetani causes tetanus (not gas gangrene); Clostridioides difficile causes antibiotic-associated pseudomembranous colitis; Clostridium botulinum causes botulism (flaccid paralysis via a neurotoxin) — none of these three are associated with gas gangrene.
