| Abstract: | The immunochemical affinity of V. cholerae enterotoxins, serovars Inaba and Ogawa, has been shown in animal experiments on cross antitoxic immunity in the small intestine, the passive hemagglutination test and the toxin neutralization test. However, antitoxic interaction with both enterotoxins is characteristic only for antibodies to V. cholerae of serovar Inaba, while in animals immune to Ogawa toxin the choleragenic effect of enterotoxins produced by V. cholerae of both serovars in retained. The possible mechanisms of one-sided cross interserovar antitoxic immunity in cholera are discussed. |
