Trypanosome Infection Rate in Glossina tachinoides: Infested Rivers of Limmu Kosa District Jimma Zone, Western Ethiopia

Abstract Objective: Trypanosomosis is a disease of domestic animals and humans resulting from infection with parasitaemic protozoa of the genus Trypanosoma transmitted primarily by tsetse flies and other hematophagous flies. The study was conducted to estimate the infection rate of trypanosome in vector flies and involved parasite species. Result: The study result indicated that there was only one species of Tsetse fly Glossinatachinoides detected with high Flay/Trap/Day = 4.45. Total of n=284 tsetse flies were dissected and n= 5 positive for Glossinatachinoidesresulting in 1.76% infection rate. Higher trypanosome infections were observed in female tsetse with significant infection rate of 1.41%, n=4 and 0.35%, n=1 in males. Furthermore, 1.06% of the trypanosome infections carried by Glossinatachinoides were classified as Trypanosomavivax and the remaining 0.70% was Trypanosomacongolense.The study confirmed the absence of human trypanosomosis in study area with only identified trypanosome parasites were Trypanosomavivax and Trypanosomacongolense. However, the resulted FTD= 4.45 recommend control and suppression of the vector and parasite is mandatory due to Pathogenic Animal Trypanosomosis.
