title: [Immunogenic and antigenic properties of continuously cultured typhoid bacteria].
abstract: It was shown that in continuous cultivation of typhoid bacilli, by changing the rate of dilution and the regimens of carbohydrate and oxygen supply it was possible to determine conditions under which the most highly immunogenic vaccines were obtained and the maximal synthesis of antigens was observed. The regimen optimal for obtaining the highly immunogenic typhoid vaccines (D = 0.4 h-1; So = 5 g/l; pO2 = 50%) coincided with the regimen at which the maximal O-antigen synthesis was seen, and failed to coincide with the regimens necessary for the greatest synthesis of Vi- and H-antigens.
