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 ...
Gangrene toes in a diabetic. Gangrene is a type of tissue death caused by a lack of blood supply. [4] The feet and hands are most commonly affected. [1] If the gangrene is caused by an infectious agent, it may present with a fever or sepsis.
Diabetic foot infection is any infection of the foot in a diabetic person. [2] The most frequent cause of hospitalization for diabetic patients is due to foot infections. [ 3 ] Symptoms may include pus from a wound, redness, swelling, pain, warmth, tachycardia , or tachypnea. [ 4 ]
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.
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.
Air can be trapped under the skin in necrotizing infections such as gangrene, occurring as a late sign in gas gangrene, [2] of which it is the hallmark sign. 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 ...

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]
