One hundred and thirteen African buffalo, Syncerus caffer, from two areas of Uganda were examined for Elaeophora poeli. The parasite was not found in 69 buffalo from the West Acholi District but was present in the aorta of 6 (14%) of 44 buffalo from the Queen Elizabeth Park. It was also found on the surface of the heart of a seventh animal. The gross appearance of the seven infections are described and illustrated. Male buffalo over 5 years of age were most frequently infected.
