[Immunogenicity of Yersinia pestis grown on nutrient media at 28 and 37 degrees C].
The immunogenicity of Y. pestis strain EV, grown in yeast-casein medium, yeast medium with Hottinger digest and yeast medium with sunflower-seed protein at 28 degrees C and 37 degrees C, for guinea pigs and white mice has been studied. As revealed in this study, these media ensure the formation of highly immunogenic populations of Y. pestis strain EV and, therefore, can be used for growing Y. pestis vaccine strains. Considerable fluctuations in the content of such highly protective antigen as fraction 1 do not affect the immunogenicity of live cultures of Y. pestis strain EV. This is due to the leveling of differences in the content of this antigen in the process of the multiplication of these bacteria in laboratory animals.
