Abstract
Anaplasmosis was experimentally transmitted from cattle to elk to cattle. Six non-splenectomized adult elk to cattle. Six non-splenectomized adult elk that were inoculated with freshly collected heparinized blood from cattle chronically infected with Anaplasma marginale became asymptomatic carriers. Although the exposed elk did not develop clinical or hematologic evidence of infection they became seropositive by the serum and plasma rapid card agglutination (RCA) tests. Blood from the experimentally infected elk produced disease in splenectomized bovine calves and the carrier state persisted for at least 1 yr. Infection did not occur when 2 elk were inoculated with 0.5 ml of frozen blood from known bovine carriers. The blood was frozen for 4 wk in liquid N with 6% dimethyl sulfoxide.This publication has 3 references indexed in Scilit:
