Immunohistochemical examination of aborted bovine tissues, collected from two dairy farms that had a high abortion rate (7 percent), detected the organism Neospora caninum (NC). Five out of 12 aborting cows (41.7 percent) were seropositive to NC using a competitive ELISA test, Neospora-tachyzoites were detected in the placenta of a seropositive aborting cow. Neither NC parasites nor cysts were detected in other fetal tissues. The identification of the Neospora-parasite and a high percentage of Neospora seropositive aborting cows, suggested NC as the possible cause of abortion. This is the first identification of the NC parasite in Thailand.
