Abstract

ABSTRACT Abortion in the equine species is responsible for major economic losses, and among the possible causes is neosporosis, a disease that is not always investigated as a probable diagnosis. Thus, the objective of this study was to report an abortion at 129 days of gestation resulting from Neospora spp. Blood samples from the mare and the aborted fetus were sent to a specialized laboratory. Under necropsy, gelatinous and hemorrhagic edema was detected in subcutaneous tissue, friable and jaundiced liver with autolysis in spleen, kidneys and adrenal glands. Fragments of the organs collected at necropsy were submitted to histopathology and infectious agent tests, which identified non-purulent hepatitis and epicarditis and purulent omphalitis. Also, a positive result for Neospora spp. by the conventional and nested Polymerase Chain Reaction (PCR) technique. Blood serum obtained from the mare was subjected to analyses to Neospora spp. by indirect immunofluorescence technique, herpesvirus by serum neutralization in cell culture and Leptospira sp. by PCR, all with negative results. Thus, it is important to consider neosporosis as a differential diagnosis in cases of abortion and stillbirth, since the presence of dogs in the properties is extremely common and represent an important source of infection.
