Prevalence of antibodies to Neospora caninum in horses in North America.
Serum samples from 296 horses slaughtered for food in the United States were tested for antibodies to Neospora caninum by the Neospora-agglutination test (NAT). Antibodies were found in 69 (23.3%) horses with titers of 1:40 (19 horses), 1:80 (19 horses), 1:100 (3 horses), 1:200 (7 horses), 1:400 (4 horses), and 1:800 (17 horses). This is the first serologic survey for N. caninum antibodies in horses.
