Trypanosoma congolense is a species of trypanosomes and is the major pathogen responsible for the disease nagana in cattle and other animals including sheep, pigs, goats, horses and camels, dogs,[2] as well as laboratory mice.

In its mammalian host, Trypanosoma congolense only lives in blood vessels, and causes in particular anaemia.

Nok et al., 2003 find T. congolense to alter the surfaces of erythrocytes which may contribute to this effect.

[5] Individuals isolated from Boran cattle in the Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993.
