Neospora caninum is a protozoan pathogen related to abortions and stillbirths of cattle around the world. We present the first results in Estonia on this parasite. For analysis of bulk milk and serum samples SVANOVIR@Neospora-ab ELISA kit (SVANOVA) were used with cut-off ≥20 % of the positive control (percent of positive value, PP). Bulk milk samples from 2007 and 2008 (N=65 and N=320) were screened, resulting in 26 and 16% herd prevalence. Additionally, two farms positive in the bulk milk testing were selected for serological examination of individual cattle (N=59 and N=20). Serum was positive for Neospora in 23% of the tested animals. Estonia has considerable levels of antibody positive herds and animals, and Neospora is likely to be a cause of abortions. Future case studies are required to verify Neospora as cause of abortions.
