[Experimental study of the participation of gamasid mites and fleas in circulating the tick-borne encephalitis virus (a review)].
The paper presents analysis of literary data on experimental infection of 11 species of gamasid mites and 10 species of fleas with tick-borne encephalitis virus (TE) and experiments on transmission of the virus to animals by 9 species of gamasids and 14 species of fleas. Nearly all investigated species can perceive the virus, preserve it from some hours to two months and transmit it to animals within a period of 24 hours to two months after experimental infection. The fact of transmission of the virus to animals was established by the presence of recipients in the brain or by the presence of antibodies. To settle the question of the possible participation of gamasids and fleas in the circulation of the virus TE in nature threshold doses of the virus for infection of mites and fleas of different species, mechanism of transmission of the virus to animals by gamasid mites, facultative haematophags , titers and terms of virusemia in animals which obtained the virus from gamasid mites or fleas should be established.
