Seroprevalence of antibodies against Neospora caninum in diagnostic equine serum samples and their possible association with fetal loss.
A case-control study of the association between the presence of serum antibodies against Neospora spp. and fetal loss was performed on serum samples submitted to a veterinary diagnostic laboratory in northwestern United States. Control sera were randomly selected from those submitted from healthy horses for routine equine infectious anemia testing required for regulatory health certification. Case sera were randomly selected from those submitted from aborting mares for diagnostic workup. Based on a 1:50 or greater titer on the indirect fluorescent antibody test, 8% of the 160 control sera and 13% of the 140 case sera were titer positive. The association odds ratio of 1.67 fell short of statistical significance (p=0.124).
