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 is a type of tissue death caused by a lack of blood supply. [4] Symptoms may include a change in skin color to red or black, numbness, swelling, pain, skin breakdown, and coolness. [1] 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.
Clostridium perfringens (formerly known as C. welchii, or Bacillus welchii) is a Gram-positive, bacillus (rod-shaped), anaerobic, spore-forming pathogenic bacterium of the genus Clostridium. [ 1 ][ 2 ]C. perfringens is ever-present in nature and can be found as a normal component of decaying vegetation, marine sediment, the intestinal tract of ...
Swiss-model. Domains. InterPro. Clostridium perfringens alpha toxin is a toxin produced by the bacterium Clostridium perfringens (C. perfringens) and is responsible for gas gangrene and myonecrosis in infected tissues. The toxin also possesses hemolytic activity.
Group A streptococcal infections are a number of infections with Streptococcus pyogenes, a group A streptococcus (GAS). [ 1 ]S. pyogenes is a species of beta-hemolytic Gram-positive bacteria that is responsible for a wide range of infections that are mostly common and fairly mild. If the bacteria enters the bloodstream, the infection can become ...
Clostridium botulinum is a gram-positive, [1] rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce botulinum toxin, which is a neurotoxin. [2][3] C. botulinum is a diverse group of pathogenic bacteria. Initially, they were grouped together by their ability to produce botulinum toxin and are now known as four ...
Clostridium septicum. Clostridium septicum[1] is a gram positive, spore forming, obligate anaerobic bacterium. Clostridium septicum can cause gas gangrene, but unlike other Clostridium species like Clostridium perfringens, no trauma is necessary at the site of the infection. It is thought that the infection is established by hematogenous spread ...
Fournier gangrene is usually diagnosed clinically, but laboratory tests and imaging studies are used to confirm diagnosis, determine severity, and predict outcomes. [2] X-rays and ultrasounds may show the presence of gas below the surface of the skin. [2] A CT scan can be useful in determining the site of origin and extent of spread. [2]
