Abstract
To assess seroprevalence of Neospora spp. in asymptomatic horses in Ankara, Turkey, 19 mares and 56 stallions older than 2 years of age were examined using ELISA; 9.3% of the horses were seropositive. Seroprevalence of N. caninum in mares was twice of that in stallions (15.8 vs 7.1%) and all appeared to be asymptomatic.
