[Biological properties of the Tahyna virus isolated in the Arctic]

The results are presented of comparative studies over the course of experimental Tahyna infection of viremia in the blood and organs, localization and patterns of lesions in the same organs after different routes of inoculation of white mice and hamsters with a new strain LEIV 9843 Mur of Tahyna virus. The results of these experiments are compared with similar studies in monkeys with asymptomatic infection, including humoral antibody detection. The pattern of lesions in the organs of animals infected with Tahyna virus (LEIV 9843 Mur strain), the mode of virus spread, tissue tropism of the virus were established. The virus thermostability and sensitivity to different pH values of the medium were determined.
