The disease has been called pig-bel because of its firm association with the pig-feasting practices of the people, which occur in 3–7 year cycles. 3.Cl. welchiitype C is believed to play an important role in the pathogenesis of the condition. Strains isolated were strongly toxigenic and uniform in their toxin production. 4. A food poisoning aetiology was not proved but circumstantial and immunological evidence suggest that pork may be a vector of the disease. 5. The source ofCl. welchiitype C was not established.
