Trypanosomosis is a disease of domestic animals and humans resulting from infection with parasitaemic protozoa of the genus Trypanosoma transmitted primarily by tsetse flies. A cross-sectional study was conducted from January-March 2018, to estimate the infection rate of trypanosome in Glossina tachinoides, their distribution, magnitude and involved trypanosome species in Limmu Kosa District of Jimma zone.
Study methodology involved entomological survey using monoconical traps to study the magnitude of Fly density Flay/Trap/Day (FTD) and tsetse fly dissection to estimate infection rate of trypanosome in vector flies. The study result indicated that there was only one species of Tsetse fly Glossina tachinoides detected with FTD = 4.45. From the total of (n = 284) dissected Glossina tachinoides flies only (n = 5) positive for Trypanosome resulting in 1.76% Infection Rate. Peak trypanosome infections were observed in female tsetse 2.04%, n = 4 and 1.14%, n = 1 in males. Furthermore, 1.06% of Glossina tachinoides were infected by Trypanosome vivax and the remaining 0.70% was Trypanosome congolense. Finally, the study concluded with the recommendation of control and suppression of the vector and parasite was mandatory due to Pathogenic Animal Trypanosomosis.
锥虫病是一种家畜和人类疾病，由感染锥虫属的寄生虫原虫引起，主要通过采采蝇传播。2018年1月至3月进行了一项横断面研究，以估计吉马地区林穆科萨区嗜人采采蝇体内锥虫的感染率、分布情况、感染程度及相关锥虫种类。
研究方法包括使用单锥形诱捕器进行昆虫学调查，以研究采采蝇密度[每诱捕器每日采采蝇数（FTD）]，并对采采蝇进行解剖，以估计媒介采采蝇体内锥虫的感染率。研究结果表明，仅检测到一种采采蝇——嗜人采采蝇，FTD = 4.45。在总共解剖的284只嗜人采采蝇中，只有5只锥虫检测呈阳性，感染率为1.76%。在雌性采采蝇中观察到锥虫感染高峰，感染率为2.04%（n = 4）；在雄性采采蝇中感染率为1.14%（n = 1）。此外，1.06%的嗜人采采蝇感染了间日锥虫，其余0.70%感染了刚果锥虫。最后，研究得出结论，鉴于致病性动物锥虫病，必须对媒介和寄生虫进行控制和抑制。
