[QUOTE="Campground Cattle, post: 25337, member: 195"] Neosporosis is a parasitic disease of many species of domestic animals caused by the protozoan Neospora caninum. In cows, the parasite can be transmitted to the fetus via the placenta and cause a variety of clinical effects including abortion. Calves born from Neospora-infected cows may exhibit neurological symptoms and die within one week after birth or may be infected with the parasite and show no clinical signs of disease. There is an urgent need control transmission of the Neospora to offspring by identifying cows infected with the parasite and removing these animals from the breeding population. The present study describes the use of a recombinant antigen-based serological assay to identify cows infected with Neospora. The level of antibodies specific for Neospora remained high in cows for at least one year after a primary neosporosis infection. Also, calves born from parasite-infected cows had high levels of Neospora-specific antibodies in their serum which remained high during the course of the study. Serum from cows which aborted a fetus due to nesoporosis had much higher levels of Neospora-specific antibodies than cows which aborted a fetus due to other causes. These results indicate that the recombinant antigen-based immunoassay is suitable for identifying Neospora-infected cows and may be useful for controlling neosporosis in the field. [/QUOTE]
