Infectious disease. 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]
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 ...
Blackleg, black quarter, quarter evil, or quarter ill ( Latin: gangraena emphysematosa) is an infectious bacterial disease most commonly caused by Clostridium chauvoei, a Gram-positive bacterial species. It is seen in livestock all over the world, usually affecting cattle, sheep, and goats. It has been seen occasionally in farmed bison and deer ...
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. [8][18]Infection spreads rapidly as the gases produced by the bacteria expand and infiltrate healthy tissue in the vicinity.
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.
Fournier gangrene is a urological emergency requiring intravenous antibiotics and debridement (surgical removal) of dead tissue. [ 2] Formation of a colostomy may be required to divert bowel motions away from the area. [ 9] In addition to surgery and antibiotics, hyperbaric oxygen therapy may be useful and acts to inhibit the growth of and kill ...
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 from the ...
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 ...
