The intraa
ual dynamics of the epidemic process caused by heterogeneous S.enteritidis population in Vladivostok with representation of the epidemic importance of each of the dominating plasmidovars was investigated. It was established that morbidity seasonal rise corresponded to August — September when the etiological importance of the microbe carrying plasmids 38: 1,4 MDa increased and it acquired the leading role in etiology of infection. The acquisition was achieved due to decrease of the etiological importance of the others (not dominating) S.enteritidis plasmidovars that reflected the reduction in heterogeneity of S.enteritidis population during epidemic distribution of the disease. It was shown that the morbidity seasonal features of salmonella infection caused by each of dominating S.enteritidis plasmidovars were peculiar. The expressiveness of Salmonella infection morbidity seasonal rise was determined by the degree of synchronous participation of every microbial plasmidovars in its formation. The comparative analysis of the Salmonella infection dynamics has revealed the possibility of smoothing of the intraa
ual course of the morbidity caused by heterogeneous by plasmid spectrum microbial population.
