Trypanosoma congolense
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,[1] 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.[1][2][3]

Drug resistance
Individuals isolated from Boran cattle in the Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993.[4] This likely indicates a permanent loss of function in this area for the tested trypanocides, Diminazene aceturate, Isometamidium chloride, and Homidium chloride.[4]
