title: Prevalence of antibodies to Neospora caninum in dogs.
abstract: Serum samples from 1077 dogs suspected of having Neospora caninum infections from 35 states in the United States and 3 provinces in Canada were tested for N. caninum IgG antibodies by the indirect fluorescent antibody test. Antibodies to N. caninum were found in 75 of 1077 (7%) of the samples. Twenty of the positive dogs were females, 17 were males and the sex was not recorded on 38 dogs. Chi square analysis indicated no differences (P > 0.05) based on sex were present. Dogs from the Southeast and Midwest regions of the United States were more likely to be N. caninum antibody positive than were dogs from the Northeast or West regions.
