Small ruminant Trypanosomosis Sheep and goats play an important role in improving the economy of small holder farmers in Ethiopia. Tsetse-transmitted animal trypanosomosis is one of the most significant and costly diseases in the country, hindering the efforts being made for food self-sufficiency. In Ethiopia, about 200,000 km2 of the land is infested with tsetse flies and the main pathogenic trypanosomes in animals are Trypanosoma congolense, T. vivax, and T. brucei. Although there have been several reports on livestock trypanosomosis, there is little data on the prevalence of trypanosomosis in sheep and goats in northwestern Ethiopia. To provide this data, we collected blood into ethylenediaminetetraacetic acid (EDTA) from 600 adult sheep and 1,810 goats in five peasant associations (PAs) in the Guangua district of northwestern Ethiopia. The packed cell volume (PCV) was measured and the buffy coat and uppermost layer of red blood cells were examined with phase contrast at x 400 for the presence of motile trypanosomes. Thick and thin blood smears were stained with Giemsa at 1:10 dilution for 30 minutes and examined under oil immersion for trypanosomes.
