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. It is the most common cause of nagana in east Africa, but is also a major cause of nagana in west Africa. This parasite is spread by tsetse flies. In its mammalian host, Trypanosoma congolense only lives in blood vessels, and causes in particular anaemia.[2][3][4][5]

Infection process
T. congolense causes anemia. Nok et al., 2003 find T. congolense to alter the surfaces of erythrocytes which may contribute to this effect.[5]
Drug resistance
Individuals isolated from Boran cattle in the Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993.[6] This likely indicates a permanent loss of function in this area for the tested trypanocides, diminazene aceturate, isometamidium chloride, and homidium chloride.[6]
