Distribution of Borna disease virus (BDV) infection outside endemic areas has been studied in several countries. We examined serum samples for anti-BDV antibodies in purebred racing horses and other domestic animals in Turkey. In total serum samples of 437 animals including 282 horses, 50 sheep, 25 goats, 50 cattle, and 30 cats were tested by indirect immunofluorescence assay (IFA). Anti-BDV antibodies were detected in 4.9% of horses, 12% of sheep, 4% of goats, 14% of cattle and 6.6% of cats. No statistical difference was observed between seroprevalence in Arabic and English purebred horses from four different racing centers (p > 0.05). Antibody titers ranged between 1:10 and 1:320. The highest antibody titers were found in sheep and horses and the lowest titer in cattle. Clinical symptoms of Borna disease were not observed in any animal of any species examined. This study confirms the presence of anti-BDV antibodies in racing horses as well as cat population in Turkey. Moreover anti-BDV antibodies are demonstrated for the first time in sheep, goats and cattle in Turkey.
