(TBE) and tick-borne borrelioses (TBB) natural foci in several sites of southern part of
Baikal region are presented. The studied territory showed high degree of heterogeneity of
adult Ixodes persulcatus population density and their infection with TBEV and borrelians.
Signi扯cant di捯erence between the studied sites regarding pathogenicity of vectors with
positive TBEV – ELISA results for laboratory mice has been revealed. Positive correlation
between vector abundance and TBEV antigen prevalence and the number of murine viral
isolates has been shown. The incidence of TBE on the studied territory also correlated with
ELISA results and success of isolation on worm-blooded animals. The number of Borrelia
PCR positive results was higher if the ticks abundance was high, but TBB incidence cor-
related neither with ticks abundance, no with their Borrelia infection rates.
