The characteristics of the Salmonella enteritidis strains isolated from patients (1632 persons) in the Maritime Territory in 2001 — 2004 and from production of the local poultry farms (89 tests) in 1996 — 2004 were investigated by comparative plasmid analysis. It was revealed that the microbial population was represented by the basic and rare occurring S.enteritidis plasmidovars. According to frequency of isolation from patients and samples of the local poultry farms the basic microbial plasmidovars were divided into the local dominating, local not dominating and imported Salmonella plasmidovars. Evidences of existence in the structure of S.enteritidis population in the Maritime Territory the local and imported parts were given. The local part of microbial population unlike the imported one was co
ected with epizootic process among hens on the local poultry farms and it was a basis for formation of the microbial plasmodovars dominating in etiology of human infection. It was shown that the microbiological centralized monitoring upon Salmonella strains isolated from patients and agricultural animals had the great value in epizootic and epidemiological surveillance.
