Abstract
Samples of blood from 27 free-roaming elk (Cervus canadensis canadensis) [a suspected anaplasmosis reservoir] from the Clearwater National Forest in north central Idaho, USA, were tested by the rapid card agglutination test and complement-fixation test for the presence of antibodies against Anaplasma marginale. The serum card test and complement-fixation test gave incomplete and false-positive reactions; the plasma card test gave no reactions. Anaplasma bodies or other blood parasites were not observed in stained smears of elk blood. Blood from 11 elk, including 2 that were serum card test-positive, did not produce clinical, hematologic or serologic evidence of infection in 3 anaplasmosis-susceptible bovine calves.
