Nagana
Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of non-human vertebrates. The disease is caused by trypanosomes of several species in the genus Trypanosoma such as T. brucei (which also infects humans to cause African Sleeping Sickness), T. vivax (which causes nagana in livestock mainly in sub-Saharan Africa, although it has also spread to South America), T. congolense and T. simiae. The trypanosomes infect the blood of the vertebrate host, causing fever, weakness, and lethargy, which lead to weight loss and anemia. In some animals, the disease is fatal if not treated. In sub-Saharan Africa, trypanosomes are transmitted by tsetse flies, which occur in more than 35 countries.
An interesting feature is the remarkable tolerance to nagana pathology shown by some breeds of cattle, notably the N'Dama – a West African Bos taurus breed. This contrasts with the susceptibility shown by East African B. indicus cattle such as the zebu.
