Detection of antibodies against Sarcocystis neurona, Neospora spp., and Toxoplasma gondii in horses from Costa Rica
Serum samples from 315 horses from Costa Rica, Central America, were examined for the presence of antibodies against Sarcocystis neurona, Neospora spp., and Toxoplasma gondii by using the surface antigen (SAG) SnSAG2 enzyme-linked immunosorbent assay (ELISA), the NhSAG1 ELISA, and the modified a...

Sumario: |
Serum samples from 315 horses from Costa Rica, Central
America, were examined for the presence of antibodies against Sarcocystis
neurona, Neospora spp., and Toxoplasma gondii by using the surface
antigen (SAG) SnSAG2 enzyme-linked immunosorbent assay (ELISA),
the NhSAG1 ELISA, and the modified agglutination test, respectively.
Anti-S. neurona antibodies were found in 42.2% of the horses by using the
SnSAG2 ELISA. Anti-Neospora spp. antibodies were found in only 3.5%
of the horses by using the NhSAG1 ELISA, and only 1 of these horses was
confirmed seropositive by Western blot. Antibodies to T. gondii were
found in 34.0% of the horses tested, which is higher than in previous
reports from North and South America. The finding of anti-S. neurona
antibodies in horses from geographical areas where Didelphis marsupialis
has wide distribution suggests that D. marsupialis is a potential definitive
host for this parasite and a source of infection for these horses. |
