Abstract

Deer are considered important intermediate hosts for the coccidian parasites, Toxoplasma gondii and Neospora caninum. Antibodies to N. caninum and T. gondii were determined in sera of 42 mule deer (Odocoileus hemionus hemionus) and 43 black-tailed deer (Odocoileus hemionus columbianus) from Washington state, USA, using direct agglutination test with specific antigens. A titer of 1:25 was considered diagnostic for both parasites. N. caninum antibodies were found in 7 of 42 mule deer and 8 of 43 black-tailed deer. T. gondii antibodies were found in 14 black-tailed deer but not in any of the mule deer. This is probably the first report of seroprevalence of N. caninum in these hosts.
