[FORMATION OF POPULATION MORBIDITY WITH SALMONELLOSIS CAUSED BY SALMONELLA ENTERITIDIS IN REGIONS WITH INCOMPLETE SUPPLY OF LOCAL POULTRY PRODUCTS]

[[[ Aim: ]]] Study plasmid characteristics of S. enteritidis strains in patients and features of epidemi- ology of the infection in regions with incomplete supply of population with local poultry produc- tion. [[[ Materials and methods: ]]] Plasmid analysis of microbe strains isolated from 382 patients and 8 samples of products was carried out, and significance of plasmid types in population morbidity was evaluated. Identification of salmonella was carried out by conventional methods, plasmid 41 specter – by Kado C.I. and Liu S.T (1981) method. [[[ Results: ]]] 98.4% of strains contained virulence plasmid p38, and 80.1% of strains also had small plasmids. Sakhalin strains were divided into 16 plasmid types (D=0.794), and strains from Jewish AO – 10 (D=0.834). Uniformity of strains in patients during infection outbreaks and in transmission factors was detected. [[[ Conclusion: ]]] Features of salmonellosis in. the studied subjects of Russian Federation are determined by higher risk of import of products containing salmonella. Monitoring based on plasmid analysis is an effective base for epidemiologic control.
