The reduction in hemoglobin, packed cell volume, RBCs and blood pictures of hypochromasia, poikilocytosis and anisocytosis were indicating anaemia which is mainly due to hemolysis by Babesia canis and also due to decreased RBC production, excessive consumption and/or destruction of blood cellular component, decreased RBC survival and lack of erythropoitic response in Ehrlichiosis as suggested by Warner (2008).
A FBC with a smear on admission revealed a hypochromic, microcytic anaemia (Hb 7.3 g/dL) with target cells, spherocytes, oval macrocytes, poikilocytosis and Howel Jolly bodies.
The presence of a leuco-erythroblastic reaction and teardrop poikilocytosis on peripheral blood smear microscopy should lead one to suspect possible BM infiltration.
Peripheral blood smear revealed severe anisocytosis, poikilocytosis, and tear-drop shaped red blood cells and bone marrow biopsy revealed a hypercellular marrow with over 95% diffuse effacement with sheets of lymphocytes and lymphoplasmacytic cells with interspersed plasma cells with scattered Mott cells and Russell bodies.
Abnormal variations in sizes and shape are termed aniso-cytosis and poikilocytosis respectively [14].
When the peripheral blood smear was observed under the microscope, the blood cells were all microcytic, hypochromic, and showing poikilocytosis and ankylocytosis without neutropenia.
