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 ...
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]
Clostridia can be diagnosed by recognizing the characteristics of the lesion of the infection along with Gram stains of the tissue and bacterial culture. [1] Although the body does not have adequate defenses alone, this microbe can be controlled with the help of antibiotics, like penicillin, and tissue debridement for the more severe cases.
Then Clostridium species take over. In the last four hours of fermentation, Lactobacillus species reproduce. One of the main rising agents, Clostridium perfringens, produces mostly hydrogen gas, as opposed to carbon dioxide gas in yeast-raised breads. Hydrogen gas is a lighter gas than carbon dioxide, which explains the dense white crumb.
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]
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 ...
Clinical features that are characteristic of anaerobicbacteremia include hyperbilirubinemia, metastatic lesions, and suppurative thrombophlebitis. The mortality rate varies between 15% and 30% and can be improved in those who are diagnosed early and receive appropriate antimicrobial therapy and their primary infection when present is resolved.
