Haematological changes in ewes experimentally infected with Trypanosoma brucei

Abstract

Changes in the haematological values were studied in West African Dwarf ewes infected with Trypanosoma brucei. This disease was characterized by a normocytic normochromic anaemia in the acute phase and a severe macrocytosis during the chronicity. The observed changes suggest inadequate erythropoiesis in the acute phase while the chronic phase had a superior but still inadequate erythropoietic response with persistent anaemia. Normal total leucocyte values were observed during the acute phase while leucocytosis was a permanent feature in the chronic phase.
