Abstract
A pure bred imported Holstein Friesian bull aged 4.5 years was brought for necropsy with
a history of treatment for suspected anaplasmosis. Gross examination revealed a
dehydrated carcass with pale mucous membranes. Pericardial sac contained about 75 mL
of serosanguineous fluid. Myocardial and subendocardialecchymotic haemorrhages were
seen in the heart. Lungs revealed patchy lobulated pattern and thickening of interlobular
septa and emphysematous areas. Hepatic parenchyma was firm and tan yellow brown. Gall
bladder contained about 25 mL of dark yellow green bile. Cortex and medulla of kidneys
were dark red brown. Urinary bladder contained about 1.5 litres of coffee coloured urine
suggesting haemoglobinuria. Peripheral and heart blood smears revealed Babesia bigemina
in the erythrocytes and morula of Ehrlichia sp. in the monocytes with anaemic changes.
Spleen imprints revealed macrophages with numerous Ehrlichia sp. Based on the above
findings, the case was diagnosed as Babesiosis and Ehrlichiosis.
