Elaeophora poeli is a parasitic nematode found in the aorta, and sometimes the heart, of various cattle throughout Asia, and in parts of Africa.

Despite the fact that it lives in nodules (aneurysms) in the walls of the aorta and heart, apparent clinical symptoms of E. poeli infestation are seldom reported.

The geographic distribution of this species includes several Asian and African nations: Democratic Republic of Congo, India, Indonesia, Malaysia, Mozambique, the Philippines, Tanzania, Thailand, Uganda, and Vietnam.

[6] The percentage of animals found to be infested in large-scale slaughterhouse studies range from 1.7% in Tanzanian Zebu (Bos primigenius indicus)[7] to over 60% in Philippine Bubalus bubalis.

One study found a strong correlation between infestation and visceral pleurisy (inflammation of the membrane that surrounds the lungs).
