Gas gangrene (also known as clostridial myonecrosis [1]) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. [2] Myonecrosis is a condition of necrotic damage, specific to ...
Clostridium perfringens is a common cause of food poisoning in the United States. C. perfringens produces spores, and when these spores are consumed, they produce a toxin that causes diarrhea. Foods cooked in large batches and held at unsafe temperatures (between 40 °F and 140 °F) are the source of C. perfringens food poisoning outbreaks.
This toxin has been shown to be the key virulence factor in infection with C. perfringens; the bacterium is unable to cause disease without this toxin. [1] Further, vaccination against the alpha toxin toxoid protects mice against C. perfringens gas gangrene. [2]
Clostridium perfringens causes a wide range of symptoms, from food poisoning to cellulitis, fasciitis, necrotic enteritis and gas gangrene. [16] [17] Clostridium tetani causes tetanus. Several more pathogenic species, that were previously described in Clostridium, have been found to belong to other genera. [6]
Hathewaya histolytica (formerly Clostridium histolyticum) is a species of bacteria found in feces and the soil. It is a motile, gram-positive, aerotolerant anaerobe. H. histolytica is pathogenic in many species, including guinea pigs, mice, and rabbits, and humans.
Skin involvement in subcutaneous tissue infections includes: cutaneous and subcutaneous abscesses, [37] breast abscess, decubitus ulcers, infected pilonidal cyst or sinus, Meleney's ulcer infected diabetic (vascular or trophic) ulcers, bite wound, [38] anaerobic cellulitis and gas gangrene, bacterial synergistic gangrene, and burn wound ...

Welch's research was principally in bacteriology, and he is the discoverer of the organism that causes gas gangrene. It was named Clostridium welchii in recognition of that fact, but now the organism usually is designated as Clostridium perfringens.
