The serosurveys conducted in the Silica plateau area of the Slovak karst region revealed the presence of specific neutralizing antibody against tick-borne encephalitis (TBE) virus in 18\% of local inhabitants (33 examined, mostly goats and sheep farmers), 54\% of goats (26 examined), 18\% of sheep (120 examined) and 13\% of cattle (60 examined), against Lipovnik (LIP) virus in 30\% of inhabitants, 88\% of goats, 55\% of sheep and 45\% of cattle, and against Bhanja (BHA) virus in 27\% of inhabitants, 46\% of goats, 29\% of sheep and 23\% of cattle. The results of hemagglutination-inhibition tests with TBE and BHA antigens were analogous. A detailed analysis of these serologic data points to a recent enhancement of the circulation of LIP and BHA viruses and to a very low TBE virus activity in this natural focus of arboviral infections. The immunological surveys of the 32 former \"Roznava disease\" patients, conducted 25 years after an extensive epidemic of a TBE virus infection that originated in Roznava in 1951, revealed the presence of neutralizing (and also hemagglutination-inhibiting) antibodies against TBE virus in as many as 78\% of cases. Antibodies against LIP and BHA viruses were also detectable in the sera of 16\% and 9\%, respectively, of these individuals. Populations of the ectoparasites examined for the presence of arbovirus comprised 231 Ixodes ricinus, 806 Dermacentor marginatus and 204 Haemaphysalis punctata ticks and 117 specimens of the louse-flies Melophagus ovinus. Two strains of arbivirus that were antigenically related to Lipovnik and Tribec viruses belonging to a group of Kemerovo viruses were isolated from male and female I. ricinus ticks collected from cattle.
