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 ...
Enterotoxemia is a condition induced by the absorption of large volumes of toxins produced by bacteria such as Clostridium perfringens from the intestines. [1] There are several strains of C. perfringens (type B, C, and D) that may lead to the development of this gastrointestinal condition. [citation needed]
Clostridium perfringens alpha toxin is a toxin produced by the bacterium Clostridium perfringens (C. perfringens) and is responsible for gas gangrene and myonecrosis ...
Because C. perfringens beta toxin shares homology with S. aureus pore-forming alpha toxin, it was hypothesized that beta toxin acts in a similar way. Upon investigation, it was found that C. perfringens beta toxin forms cation-selective pores in cell membranes [4] of 1.6–1.8 nm [5] and results in swelling and lysis in HL60 cells. [6]
Clostridial necrotizing enteritis (CNE) is a severe and potentially fatal type of food poisoning caused by a β-toxin of Clostridium perfringens, [1] Type C. It occurs in some developing regions, particularly in New Guinea, where it is known as pig-bel.
Clostridium perfringens is an anaerobic, gram-positive bacteria that is often found in the large and small intestines of humans and other animals. Clostridium perfringens has the ability to reproduce quickly producing toxins relating to the cause of diseases.
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. [9] [19] Infection spreads rapidly as the gases produced by the bacteria expand and infiltrate healthy tissue in the vicinity.
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]
