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 ...
Gas gangrene is a bacterial infection that produces gas within tissues. It can be caused by Clostridium , most commonly alpha toxin -producing C. perfringens , or various nonclostridial species. [ 11 ] [ 21 ] Infection spreads rapidly as the gases produced by the bacteria expand and infiltrate healthy tissue in the vicinity.
Clostridium perfringens is the most common bacterial agent for gas gangrene. [45] Gas gangrene is induced by α-toxin that embeds itself into the plasma membrane of cells and disrupts normal cellular function by altering membrane structure. [8] Some symptoms include blisters, tachycardia, swelling, and jaundice. [45]
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]

Myonecrosis is the death of individual muscle fibres due to injury, hypoxia, or infection. Common causes include spontaneous diabetic myonecrosis (a.k.a. diabetic muscle infarction) and clostridial myonecrosis (a.k.a. gas gangrene). [11] Some spider bites may lead to necrosis.
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]
They are considered a virulence factor, facilitating the spread of gas gangrene. They normally target the connective tissue in muscle cells and other body organs. [1] Collagen, a key component of the animal extracellular matrix, is made through cleavage of pro-collagen by collagenase once it has been secreted from the cell. This stops large ...
