[Determination of the enterotoxic properties of Bacillus cereus].

Using indirect biological investigations and various experimental models the enterotoxic properties of 60 strains of B. cereus were determined. The determination of biochemical and enzymatic features was insufficient for indicating the enterotoxic strains and differentiating them from the non-enterotoxic ones. In the dermonecrotic test, vascular permeability test and in cultures on cells reliable criteria for determination of enterotoxicity were obtained as confirmed by the response of the ileum. The criterion of enterotoxicity determined in these tests requires raising of the index of ileum pathogenicity to 0.33.
