Abstract:

Two trends in the development of intestinal vaccines are considered creation of vaccines based on factors of pathogeneticity of the causative agent and creation of live vaccines. The importance of residual virulence is discussed. Significant immunogenic activity has been observed in a number of salmonella and shigella mutants, dependent on a number of limiting growth and propagation factors quanine, streptomycin, methionine, which are not available in the host organism. Strict doses of a limiting factor is considered to be important in immunization with dependent cultures, for immunogenesis stimulation, and sometimes, for more rapid elimination of the immunizing culture from the organism. A streptomycin-resistant revertant of Salmonella quertneri was obtained, which possessed residual virulence and higher immunogenic properties than the parental streptomycin-dependent culture. Author
