Multiple Choice

Gas gangrene is caused by which type of organism?

Gas gangrene, or clostridial myonecrosis, is caused by Clostridium species, most notably Clostridium perfringens. These bacteria are obligate anaerobes that form spores and appear as slender rods. In a poorly oxygenated, necrotic wound, they multiply and release potent toxins, leading to rapid tissue destruction and gas production as a byproduct of their anaerobic metabolism. That combination—anaerobic growth and spore formation—best fits the description of the organism responsible. The other options describe organisms that are aerobic or non-spore-forming, which do not cause gas gangrene.
