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 .
Certain domestic ruminant breeds in sub-saharan Africa show remarkable resistance to the effects of African trypanosomiasis: they can tolerate the parasites's presence while controlling parasitaemia levels and, most importantly, do not show the severe anemia and production loss that are typical of infection in susceptible breeds.
African trypanosomiasis is an insect-borne parasitic infection of humans and other animals. [ 3 ] Human African trypanosomiasis (HAT), also known as African sleeping sickness or simply sleeping sickness , is caused by the species Trypanosoma brucei . [ 3 ]
The main approaches to controlling African trypanosomiasis are to reduce the reservoirs of infection and the presence of the tsetse fly. Screening of people at risk helps identify patients at an early stage. Diagnosis should be made as early as possible and before the advanced stage to avoid complicated, difficult and risky treatment procedures.
Surra (from the Marathi sūra, meaning the sound of heavy breathing through nostrils, of imitative origin) [1] is a disease of vertebrate animals.

The tsetse is an obligate parasite, which lives by feeding on the blood of vertebrate animals. Tsetse has been extensively studied because of their role in transmitting disease. They have pronounced economic and public health impacts in sub-Saharan Africa as the biological vectors of trypanosomes, causing human and animal trypanosomiasis. [4] [5]
