| Abstract: | The data obtained during the study of the morphological changes in the internal organs and blood of 6 mouse strains at the early stages of anti-plague immunity are presented. It has been established that the introduction of 5.10(3) and 1.10(5) m. b. of the EV vaccine strain resulted in the development of morphological changes typical of residual virulence. The degree of these changes depended on the haplotype of the animals and the dose used. The most resistant to injury induced by EV strain were CBA mice (haplotype H-2k) and the most sensitive were C57BL/6 mice (haplotype H-2b). |
