Almost the entire territory of Belarus is believed to be endemic for tick-borne encephalitis virus (TBEV), with the Central European subtype, also known as TBEV-EU (Figure 1). In all, 96 counties (i.e., 71.5% of all administrative districts) are considered to be risk areas for tick-borne encephalitis (TBE). The most intensive natural foci have been found in the western part of the country (Brest and Grodno Area), and infections in these areas account for an average of 40% each of the total number of reported cases

European Subtype

Tick-borne encephalitis virus (TBEV) is classified into three subtypes: Far Eastern (TBEV-FE), European (TBEV-EU) and Siberian (TBEV-SIB). In Russia, these are also called genotypes 1, 2 and 3, respectively. Geographically, TBEV-EU dominates in Central and Northern Europe, but its representatives are also found to the east - along the southern part of the forest zone of extratropical Eurasia - up to Eastern Siberia and South Korea. However, the strains isolated outside Europe remain poorly investigated. In the proposed study, eight full genomes of the Siberian isolates of TBEV-EU were determined and 13 complete genomes were compared. The analysis of 152 full-genome TBEV sequences showed that the TBEV-EU has a higher degree of stability of the genome-coding region in the entire Eurasian area (3.1% of differences) compared to TBEV-FE (6.6%) and TBEV-SIB (7.8%). At the same time, the maximum differences are observed not between European and Siberian strains, as one could expect, but between the representatives from Europe - TBEV strains Mandl-2009 from Norway and Hypr from the Czech Republic. The studied strains from Siberia form the compact genetic cluster of 42 TBEV-EU strains and are divided into two subclusters - West Siberian and East Siberian variants. These variants differ in the combinations of amino acid substitutions in all proteins except NS2B. The West Siberian variant mostly circulates in the territory of Altai, and the closest relative of its representatives is Absettarov strain from the European part of Russia. The strains similar to the East Siberian variant of the European subtype were recorded in the Altai (strain 84.2, 2007) and in Belarus (N256, about 1940).

The aim of the study was to determine the ecology features of tick-borne encephalitis virus (TBEV) of European subtype circulating in Siberia. The strains of European subtype TBEV from Siberia were isolated in areas with different terrain types - from the plains to the midlands. The strains isolation areas differed in variety of landscapes, flora and fauna and were characterized by the presence of sharp-continental, or in some places - quite harsh climate. The composition of the main vectors and reservoir hosts of TBEV of European subtype in Siberia has its own features and is significantly different from that one in Europe. However, in spite of this, the homology of TBEV strains of European subtype isolated in different parts of habitat range of the virus from the Scandinavian countries in the West to its Eastern borders is much higher than the homology level degree of TBEV strains of FarEastern and Siberian subtypes.
