An analytical cross-sectional study was performed between November 2015 and April 2016 at Hawa Galan woreda, Kelem Wollega Zone, Oromia Region, Ethiopia, to estimate the proportion of cattle with trypanosomosis and to evaluate the elements associated with the prevalence of bovine trypanosomosis. A haemoparasitological examination of the Buffy coat method was implemented to determine the proportion of trypanosomosis-positive cattle. A study population of 428 bovines was randomly selected from three peasant associations (PAs) and tested for the presence of the disease. Findings of the laboratory results indicate that among all animals tested at the study time, 26 (6%) animals were positive for the disease. Among the positive results, the proportion of trypanosome species was 18 (69.3%) and 8 (30.7%). The prevalence at the selected PAs was 12.5%, 3.8%, and 3% for Lemlem, Madawalkituma, and Ifajiru, respectively. From this finding, the relationship has a statistically significant variation ( < 0.05) among peasant associations and body condition state, and the proportion was significantly greater ( < 0.05) in animals categorized under poor body condition score. The relationships between age and sex of cattle show no statistically significant variation among them ( > 0.05). This study indicates that the proportion of trypanosomosis was greater in anemic (PCV<24%) cattle than nonanemic (PCV≥24%). Therefore, based on this finding, the proportion of bovine trypanosomosis is evident that can cause a major effect on the health of cattle in the study population in the study area. So, effective control methods could be applied to decrease the disease and its related economic loss.
2015年11月至2016年4月，在埃塞俄比亚奥罗米亚州凯莱姆沃莱加区哈瓦加兰县开展了一项分析性横断面研究，以估算患有锥虫病的牛的比例，并评估与牛锥虫病流行率相关的因素。采用血沉棕黄层法进行血液寄生虫学检查，以确定锥虫病阳性牛的比例。从三个农民协会中随机选取428头牛作为研究对象，检测该疾病的存在情况。实验室结果表明，在研究期间检测的所有动物中，有26头（6%）动物呈疾病阳性。在阳性结果中，锥虫种类的比例分别为18头（69.3%）和8头（30.7%）。在选定的农民协会中，莱姆莱姆、马达瓦尔基图马和伊法吉鲁的流行率分别为12.5%、3.8%和3%。据此发现，农民协会与身体状况之间的关系存在统计学显著差异（P<0.05），且在身体状况评分较差的动物中，该比例显著更高（P<0.05）。牛的年龄和性别之间的关系在它们之间没有统计学显著差异（P>0.05）。本研究表明，贫血（红细胞压积<24%）牛的锥虫病比例高于非贫血（红细胞压积≥24%）牛。因此，基于这一发现，牛锥虫病的比例明显会对研究区域内研究人群中的牛的健康产生重大影响。所以，可以应用有效的控制方法来减少该疾病及其相关的经济损失。
