A review of pigbel (necrotising enteritis) in Papua New Guinea, 1961-1984.

Pigbel has been recognised as a major cause of mortality and morbidity in the Papua New Guinea Highlands for over 20 years. The clinical features, epidemiology and pathogenesis of this disease have been elucidated, leading to the development of an effective vaccine (Clostridium perfringens type C beta toxoid) for the prevention of pigbel.
