Abstrakt: Calves infected with Trypanosoma congolense TREU 112 had, at the onset of anemia, a very low total white cell count and neutropenia but with chronicity there was lymphocytosis. Infected calves had a marked reduction in granulocyte mobilization for the first 14 weeks of infection and there was reduced ability to mount an inflammatory response during the onset of anemia. Bone marrow aspiration biopsies showed marked erythroid hyperplasia in response to the anemia with a relative and likely absolute reduction in myeloid precursors and marrow granulocyte reserves.
