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 ...
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.
The major virulence factor of C. perfringens is the CPE enterotoxin, which is secreted upon invasion of the host gut, and contributes to food poisoning and other gastrointestinal illnesses. [3] It has a molecular weight of 35.3 kDa, and is responsible for the disintegration of tight junctions between epithelial cells in the gut. [6]
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.
Enteritis necroticans is an often fatal illness, caused by β-toxin of Clostridium perfringens. [16] This causes inflammation and segments of necrosis throughout the gastrointestinal tract. It is most common in developing countries; however, it has also been documented in post-World War II Germany. [16]
