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 ...
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 alpha toxin is a toxin produced by the bacterium Clostridium perfringens (C. perfringens) and is responsible for gas gangrene and myonecrosis ...
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]
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 species (Clostridium perfringens, Clostridium septicum, and Clostridium sordellii) [4] In polymicrobial (mixed) infections, Group A Streptococcus (S. pyogenes) is the most commonly found bacterium, followed by S. aureus. [10] However, when the infection is caused solely by S. pyogenes and/or S. aureus, it is classified as a Type II ...
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]
