The treatment of Clostridium perfringens infections depends on the type and severity of the condition. For severe infections, such as gas gangrene (clostridial myonecrosis), the primary approach involves surgical debridement of the affected area. This procedure removes devitalized tissue where bacteria grow, which limits the spread of the ...
This toxin has been shown to be the key virulence factor in infection with C. perfringens; the bacterium is unable to cause disease without this toxin. [1] Further, vaccination against the alpha toxin toxoid protects mice against C. perfringens gas gangrene. [2]
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.
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]
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.
The key Clostridium septicum virulence factor is a pore-forming toxin called alpha-toxin, though it is unrelated to the Clostridium perfringens alpha-toxin. Clostridium sordellii can also produce two major toxins: all known virulent strains produce the essential virulence factor lethal toxin (TcsL), and a number also produce haemorrhagic toxin ...
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 ...
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 ]
