title: High prevalence of antibodies to Neospora caninum in white-tailed deer (Odocoileus virginianus).
abstract: Serum samples of 400 white-tailed deer (Odocoileus virginianus) from 16 preserves in northeastern Illinois were tested for Neospora caninum antibodies in the N. caninum agglutination test using mouse-derived N. caninum tachyzoites and mercaptoethanol. Antibodies were found in 162 deer with titres of 1:40 (47 deer), 1:80 (32 deer), 1:160 (17 deer), 1:200 (eight deer), 1:400 (19 deer), 1:800 (17 deer) and > or = 1:1600 (22 deer). There were no significant differences in prevalence between age or sex of the deer. The high prevalence of N. caninum infection in deer is consistent with a sylvatic cycle of N. caninum.
