Prevalance of antibodies to neospora caninum in two species of wild canids, lycalopex gymnocercus and cerdocyon thous from brazil. Veterinary Parasitology 123:275-277.Interpretive Summary: Neospora caninum is a single-celled parasite of livestock.  It is a major cause of abortion in dairy cattle worldwide.  Domestic dogs are the only known reservoir hosts.  Scientists at the Beltsville Agricultural Research Center and the University of S o Paulo, Brazil have found antibodies to Neospora in two new species of wild canids, Cerdocyon thous and Lycalopex gymnocercus .  These findings will be of interest to biologists, parasitologists and veterinarians.
                                Technical Abstract: Domestic dog is the only known definitive host for the protozoan Neospora caninum that causes abortion in dairy cattle. In the present study, antibodies to N. caninum were sought in three species of wild canids, Cerdocyon thous, Lycalopex gymnocercus and Dusicyon vetulus from Brazil.  Antibodies to N. caninum were assayed by the indirect fluorescent antibody test (IFAT) and the Neospora agglutination test (NAT).  N. caninum antibodies were found in five of 12 L. gymnocercus with IFAT titers of 1:50 in 3, 1:100 in 1, and 1:1600 in 1, and NAT titers of 1:40, 1:80, 1:160, 1:320, and 1:640 in 5 animals.  Antibodies to N. caninum were found in four of 15 C. thous with IFAT titers of 1:50 in 1, and 1:100 in 3, and NAT titer of 1:40 in 1 animal. All 30 D. ventulus were seronegative by IFAT and NAT.
