970 samples of Ixodes ricinus were collected in various areas within the investigated terrain in order to detect the causes of Tick Borne Encephalitis (TBE) in humans. At the same time the prevalence of antibodies to Toxoplasma gondii and TBE virus were detected in goat population within this area. Blood sera were tested by the Waldeland modified micro titration Dye Test (DT) for Toxoplasma gondii, and ELISA and HAI tests were also used to investigate seroprevalence to the TBE virus. It was found that 4 out of the 5 tested goats herds had Toxoplasma gondii and TBE virus antibodies. 52.63 % of small ruminants had antibodies to T. gondii and 11.8 % to TBE virus in the infected herds of the tested goats. Significant differences were also observed between age groups (P<0.05).
