[The ecology and prevalence of arboviruses on the territory of the Saratov Region].

The territorial spread of Tahyna, Batai, Sindbis, West Nile fever and Crimean-Congo hemorrhagic fever viruses throughout the Saratov region in 1998 - 2000 was analyzed. The characteristics of the epizootic activity of the natural foci of these arboviruses in different landscape zones (temperate forest-steppes, steppes and semi-deserts) were calculated. The species composition of small mammals, the natural reservoirs of the causative agents of arbovirus infections, was determined.

[Anti-arbovirus antibodies positive serum screening in population of Saratov].

Seroepidemiological studies revealed the existence of a population stratum immune to West Nile and Sindbis viruses in the Saratov region. Screening of 218 sera showed that the stratum immune to arboviruses increased from 1998 to 2000. The incidence of antibodies to Batai and Sindbis viruses was the highest.

[The antigenic characteristics of field strains of the rabies virus from different districts of the USSR studied using antinucleocapsid monoclonal antibodies].

98 rabies virus strains isolated from different species of wild and domestic animals have been studied by means of 36 monoclonal antibodies obtained from the Wistar Institute (USA) and 3--of the Federal Research Center on Viral Diseases of Animals (FRG). The antigenic variants determined in this study have been analyzed in comparison with the data obtained in other regions of the world, thus establishing the spread of these variants and their relationship with different species of animals.
