Steer with bovine trypanosomiasis Cachectic dog infested with T. congolense after travel in West Africa. Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of vertebrates. The disease is caused by trypanosomes of several species in the genus Trypanosoma such as T. brucei.
Diagnosis relies on recognition of the flagellate on a blood smear. Motile organisms may be visible in the buffy coat when a blood sample is spun down. Serological testing is also common. One common way in which trypanosomiasis can be diagnosed in humans is through the detection of antibodies against trypanosomes made by host organisms. [6]
Another large group of vectors are flies. Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another ...

Surra (from the Marathi sūra, meaning the sound of heavy breathing through nostrils, of imitative origin) [1] is a disease of vertebrate animals. The disease is caused by protozoan trypanosomes , specifically Trypanosoma evansi , of several species which infect the blood of the vertebrate host, causing fever , weakness, and lethargy which lead ...

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.
