Abstract

Gross and histopathological changes were recorded in a pregnant cattle died of clinical anaplasmosis, a tick transmitted economically important disease caused by Anaplasma marginale.

Microscopically, in lungs variable extend of interstitial pneumonia, emphysema along with infiltration of mononuclear cells was seen. Spleen showed extensive increase in red pulp area with massive proliferation of lymphocytes. In liver marked thickening of capsule with fatty changes along with retention of bile was seen.
