Detection of antibodies to Neospora caninum in two species of wild canids, Lycalopex gymnocercus and Cerdocyon thous from Brazil.
Domestic dog (Canis domesticus) and the coyote (Canis latrans) are the only known definitive hosts 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 fluore...
متن کاملSerological evidence of human infection with the protozoan Neospora caninum.
Neospora caninum is a protozoan parasite that is closely related to Toxoplasma gondii. Dogs are a definitive host. Prior to its discovery in 1988, N. caninum infection in animals was often mistakenly diagnosed as toxoplasmosis. Neosporosis in animals is characterized by encephalitis, abortion, and other conditions that clinically and pathologically resemble toxoplasmosis. The potential of N. ca...
متن کاملCanine parvovirus infection in South American canids.
Canine parvovirus (CPV) infections occurred in 5 of 35 South American canids at the Department of Conservation (DC), a breeding facility of the National Zoological Park in Front Royal, Va. The clinical signs were anorexia, lethargy, diarrhea, and vomiting. Three of the affected canids survived and had high hemagglutination-inhibition titers to CPV in the recovery period. Necropsy of the 2 that ...
متن کاملNeospora caninum antibodies in wild carnivores from Spain.
Serum samples from 251 wild carnivores from different regions of Spain were tested for antibodies to Neospora caninum by the commercial competitive screening enzyme linked immunosorbent assay (c-ELISA) and confirmed by Neospora agglutination test (NAT) and/or by indirect fluorescent antibody test (IFAT). Samples with antibodies detected by at least two serological tests were considered seroposi...
متن کاملTransmission of Neospora caninum between wild and domestic animals.
To determine whether deer can transmit Neospora caninum, brains of naturally infected white-tailed deer (Odocoileus virginianus) were fed to 4 dogs; 2 of these dogs shed oocysts. Oocysts from 1 of the dogs were tested by polymerase chain reaction and found to be positive for N. caninum and negative for Hammondia heydorni. The internal transcribed spacer 1 sequence of the new strain (designated ...
