title: Characteristics of some tick--borne encephalitis virus strains isolated in Slovakia.
abstract: Several tick-borne encephalitis (TBE) virus strains isolated in Slovakia from 1974-1978 were characterized by their cytophatic abilities, sensitivity to heating at 50 degrees C and to 2 M urea, and pathogenicity for white mice. Strains isolated from Ixodes ricinus ticks differed in pathogenic properties from those isolated from Clethrinomys glareolus. The latter strains (Skalica) may be considered a spontaneous variant of TBA virus with decreased virulence for mice.
