Cl. welchii, Bacillus aerogenes capsulatus, B. phlegmonis emphysematosae.
Clostridium perfringens is a ubiquitous organism whichcommonly contaminates meat products and poultry.
Food poisoning is caused mainly by some strains of Type A, while necrotising enteritis is caused by Type C strains. The former produce alpha and theta toxins, and a heat-labile entero-toxin, while the latter produce mainly beta toxin.
About 8 to 24 hours.
· Abdominal pain, diarrhoea, vomiting. The disease is usually self-limiting, lasting for 12 to 48 hours. Necrotising enteritis is characterised by more severe manifestations and is often fatal.
· Systemic distribution of Cl. perfringens type A, and its toxins, has been suggested as a possible cause of sudden infant death syndrome in immunologically compromised infants.
· Supportive measures.
