Clostridium perfringens food poisoning can also lead to another disease known as enteritis necroticans or clostridial necrotizing enteritis, (also known as pigbel); this is caused by C. perfringens type C. This infection is often fatal. Large numbers of C. perfringens grow in the intestines and secrete exotoxin. This exotoxin causes necrosis of ...
This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. [2] Myonecrosis is a condition of necrotic damage, specific to muscle tissue. It is often seen in infections with C. perfringens or any of myriad soil-borne anaerobic bacteria.
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]
Gangrene is a type of tissue death caused by a lack of blood supply. [4] Symptoms may include a change in skin color to red or black, numbness, swelling, pain, skin breakdown, and coolness. [1] The feet and hands are most commonly affected. [1] If the gangrene is caused by an infectious agent, it may present with a fever or sepsis. [1]
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.
Most species of the genus Clostridium are saprophytic organisms that ferment plant polysaccharides [2] and are found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus Clostridium are among
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.
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]
