Bovine trypanosomosis remains a vital livestock disease and constraint which is intimidating livestock health and production, regardless of ongoing tsetse and trypanosomosis control struggles in Jimma Arjo district, East Wollega zone, Ethiopia.
A cross-sectional study was carried out with the objective of determining prevalence of cattle trypanosomiasis and apparent tsetse fly density in six randomly selected peasant associations of Jimma Arjo District from April 2018 to January 2019.
From overall 819 arbitrarily selected cattle (n= 36; 4.39%), infection rate was recorded. Selected animals were invariably infested with different trypanosome species among which (80.55%) was the most common, followed by (11.11%), (5.55%) respectively. Co-infection of and accounted for 2.77% of total infection rate. This finding indicates a statistically significant difference (p<0.05) among good, medium, and poor body condition animals with respect to Tryapanosomosis infection rate. Poor body condition animals were highly infected with trypanosome parasite as compared to medium and good body condition score animals. This study shows statistically significant association was obtained between mean packed cell volume (PCV) and trypanosomiasis infection rate (P<0.05). The lower mean PCV value (21.14%) were highly affected as compared with high mean PCV value animals (25.26%). The result of entomological survey, by using mono pyramidal traps deployed near animal grazing field and rivers of selected peasant association (PA), showed presence of four species namely , , , and with high fly density per trap in Meta PA. Higher catches of were registered as compared to other vectors.
Generally, this study indicated the disease is still a main problem for livestock health and production in the study area and it necessitates disease and tsetse fly control.
尽管埃塞俄比亚东沃莱加区吉马阿尔乔地区一直在努力控制采采蝇和锥虫病，但牛锥虫病仍然是一种严重的家畜疾病，对家畜健康和生产构成威胁。
2018年4月至2019年1月，在吉马阿尔乔地区随机选择的6个农民协会中开展了一项横断面研究，目的是确定牛锥虫病的流行率和采采蝇的表观密度。
在总共819头随机选择的牛中（n = 36；4.39%）记录到感染率。所选动物均感染了不同的锥虫种类，其中 （80.55%）最为常见，其次分别是 （11.11%）、 （5.55%）。 和 的共同感染占总感染率的2.77%。这一发现表明，在身体状况良好、中等和较差的动物中，锥虫病感染率存在统计学显著差异（p<0.05）。与身体状况中等和良好的动物相比，身体状况较差的动物感染锥虫寄生虫的比例更高。本研究表明，平均红细胞压积（PCV）与锥虫病感染率之间存在统计学显著关联（P<0.05）。与平均PCV值较高的动物（25.26%）相比，平均PCV值较低（21.14%）的动物受影响更大。通过在选定农民协会（PA）的动物放牧地和河流附近设置单锥形诱捕器进行的昆虫学调查结果显示，存在四种采采蝇物种，即 、 、 和 ，其中梅塔PA每个诱捕器的采采蝇密度很高。与其他病媒相比， 的捕获量更高。
总体而言，本研究表明该疾病仍然是研究地区家畜健康和生产的主要问题，需要对疾病和采采蝇进行控制。
