Trypanosomiasis is a vector-borne disease caused by several species of protozoan parasites, called trypanosomes [6]. T. vivax is a parasite of domestic and wild ruminants and of horses. Figure 5. West African goats are mostly reared because they have a high resistance to trypanosomiasis, and are also known for their intelligence. Pathological examination of nineteen animals (13 sheep and 6 goats) experimentally infected with Trypanosoma vivax showed that, except for mild splenomegaly, no significant gross lesions were encountered despite the marked loss of condition associated with the disease. T.congolense. trypanosomiasis occurs. When clinical cases occur, the whole group should be treated. The peak transmission period was between 1 and 3 months after the peak tsetse fly density, which raises the possibility of effective strategic prophylaxis. Trypansomes and trypanosomiasis.

Clinical manifestations of the trypanosomiasis in livestock and other domestic animals. African animal trypanosomiasis can be caused by several species of trypanosomes: Trypanosoma congolense is found in most domestic mammals: cattle, sheep, goats, horses, pigs, camels and dogs; and also in many wild animals (Figure 1). A study to compare the profitability of rearing sheep and goats under natural trypanosomosis challenge was carried out on Galana ranch in south-eastern Kenya between July 1996 and October 1997.

Hendy, C., 1988. Diminazene aceturate is one of a limited number of compounds currently marketed for treatment of trypanosomiasis in cattle, sheep and goats. Of this total, 19 (7.4%) sheep and 18 (5.0%) goats were positive giving a total infection rate of 37 (6.0%), 22 being positive with Trypanosoma vivax, 9 with T. congolense and 6 with T. brucei. Dwarf sheep and goats are the most common ruminant species found; there were an estimated 14 million dwarf sheep and goats within the zone in 1979 (Jahnke, 1982). This study established that isometamidium metabolism differs between sheep and goats and this difference may have important implications in high tsetse challenge areas.

Consequently, a similar prevalence of trypanosomiasis in trypanotolerant cattle and small ruminants living in the same environment strongly indicates that sheep and goats are, indeed, less trypanotolerant than cattle and points to a longer duration of parasitaemia and a less efficient self-cure in the sheep and goats. in Cattle, Goats, Sheep, Camels, Horses and Dogs. Methods: In this study, 193 samples from cattle, sheep, and goats were collected from eight sites. Prevalence of trypanosomiasis in sheep and goats in a region of northern Nigeria.
