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.
The two most prominent infections of GAS are both non-invasive: strep throat (pharyngitis) where it causes 15–30% of the childhood cases and 10% of adult cases, and impetigo. [4] These may be effectively treated with antibiotics. Scarlet fever is also a non-invasive infection caused by GAS, although much less common.
It is thought that the infection is established by hematogenous spread from the gastrointestinal tract. Gas gangrene caused by Clostridium septicum is associated with colorectal cancer and other defects of the bowel. [2] Clostridium septicum causes myonecrosis through the release of exotoxins such as the alpha toxin, lethal toxin, and hemolytic ...
This is a subtype of Type I infections affecting the groin and perianal areas. [10] Clostridia account for 10% of overall type I infections and typically cause a specific kind of necrotizing fasciitis known as gas gangrene or myonecrosis. Type II infection: This infection accounts for 20 to 30% of cases, mainly involving the extremities.
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]
Subcutaneous emphysema is also considered a hallmark of Fournier gangrene. [26] Symptoms of subcutaneous emphysema can result when infectious organisms produce gas by fermentation. When emphysema occurs due to infection, signs that the infection is systemic (i.e. that it has spread beyond the initial location) are also present. [9] [21]
Hathewaya histolytica can cause gas gangrene, an acute infection of pain, fever, myonecrosis, and massive edema. If not controlled, the infection can result in systemic toxemia, multiorgan failure, and even death. Further, this infection can progress to life-threatening in a matter of hours. [11]
