[Trial of the toxins of the Sonne microbe and cholera vibrio in an isolated loop of mouse small intestine].

Enterotoxic properties of neuro-and endotoxins of Sonne dysentery bacillus, of cholerogen, and Bowen's cholera vibrio endotoxin were determined on a model of an isolated loop of the mouse small intestine. In definite doses all the mentioned preparations could induce dilatation of the isolated loop of the mouse small intestine. In case of Sonne bacillus neurotoxin this property correlated with the toxicity of the preparation for the animals and failed to depend on the virulence and biochemical reference of the strain from which it was obtained. Marked variations in the sensitivity of mongrel and linear mice to the mentioned preparations were noted.
