title: Prevalence of food-poisoning (enterotoxigenic) Clostridium perfringens type A in blood and fish meal.
abstract: Four of 9 strains of Cl. perfringens type A isolated from 4 of 7 blood meal and 5 of 12 fish meal samples were found to be enterotoxigenic on biological tests and immunodiffusion test with enterotoxin specific serum. Enterotoxin produced by these strains was identical with that of food-poisoning strains. Of these 4 strains, 3 were heat-resistant and 1 was heat-sensitive spore formers. Rate of sporulation of enterotoxigenic strains was greater than the non-enterotoxigenic ones. Animal and public health significance of these strains were discussed.
