title: [Immunochemical and biochemical characteristics of a preventive preparation against cholera, cholerogen-toxoid].
abstract: Cholerogen-toxoid served as a complex vaccine preparation composed of the main pathogenicity factors of cholera vibrio--cholerogen (toxoid), endotoxin and a number of exoenzymes. The preparation contains 65 +/- 7.5% of protein, 12 +/- 1.2% of reducing sugars, 7 +/- 1.2% of lipids, and 2 +/- 0.3% of nucleic acids. Analytic disc-electrophoresis in polyacrylamide gel and immune disc-electrophoresis revealed at least seven individual proteins with the serological activity in the preparation. About 70% of these constituted toxoid proper; the content of O-antigen was 22%. In the cholerogen-toxoid there were revealed seven exoenzymes of cholera vibrio; proteinase, lecithinase, lipase, DNA-ase, RNA-ase, hyaluronidase, amylase. Antibodies against proteinase, lecithinase, amylase and RNA-ase of cholera vibrio were found in the serum of rabbits immunized with cholerogen-toxoid.
