title: Prevalence of antibodies to Neospora caninum in horses in North America.
abstract: 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.
