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 ...
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]
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]
Clostridium is a genus of anaerobic, Gram-positive bacteria.Species of Clostridium inhabit soils and the intestinal tracts of animals, including humans. [1] This genus includes several significant human pathogens, including the causative agents of botulism and tetanus.
The Clostridiaceae are a family of the bacterial class Clostridia, and contain the genus Clostridium.. The family Clostridiaceae (scientific name) defined by the taxonomic outline of Bergey's Manual of Systematic Bacteriology contains as its core the genus Clostridium (sensu stricto), as well as Acetivibrio, Acidaminobacter, Alkaliphilus, Anaerobacter, Caloramator, Caloranaerobacter ...
Genus Romboutsia: Clostridium lituseburense, reassugned in 2014. Genus Sarcina: Clostridium maximum and C. ventriculi. Originally described in Sarcina, proposed to be moved to Clostridium in 2016 but remained due to Sarcina being the older genus. Genus Terrisporobacter: Clostridium glycolicum and C. mayombei, reassigned in 2014. Family ...
Tyzzer's disease is an acute epizootic bacterial disease found in rodents, rabbits, dogs, cats, birds, pandas, deer, foals, cattle, and other mammals including gerbils [1] and spinifex hopping-mice (Notomys alexis). [2]
