A cross-sectional study was conducted from March 2019 to February 2020 with the objective of identifying ixodid ticks and haemoparasites, in extensively managed livestock, in Alle district, Southwestern Ethiopia. The study area is assumed to be free from ticks, and there had been no diagnostic and treatment options for tick-borne diseases. Among 384 heads of cattle examined for tick infestation and haemoparasites, 139 (36.19%) were infested with one or more tick species and 25 (6.51%) were haemoparasitised. Two genera of ticks, and formerly (), and four species ( and ) were identified. The haemoparasite identified was . Among the risk factors, body condition score and season of the year were found to be significantly associated with tick infestation with = 9.919, > 0.05 and = 6.216, > 0.05, respectively, at 95% CI. Tick infestation was found to be significantly associated with haemoparasitemia with = 22.2 and > 0.05, at 95% CI. The finding of the current study is an alarm ring, as the veterinary service had been not considering any haemoparasitemia in the potential list of differential diagnosis and no treatment inputs have been availed for that purpose. Thus, it is recommended that the veterinary service delivery system in the area should take haemoparasites diagnosis and avail treatment alternatives, particularly tick-borne diseases. Furthermore, there should be a strategical approach in controlling tick-borne diseases in the area before the tick-borne diseases get prevalent and where the control after high prevalence could not be easy in extensive livestock management.
2019年3月至2020年2月开展了一项横断面研究，目的是在埃塞俄比亚西南部的阿勒地区识别粗放管理的家畜身上的硬蜱和血液寄生虫。研究区域此前被认为没有蜱虫，且没有蜱传疾病的诊断和治疗方法。在检查蜱虫感染和血液寄生虫的384头牛中，139头（36.19%）感染了一种或多种蜱虫，25头（6.51%）感染了血液寄生虫。鉴定出了两个蜱属，即之前的 和 ，以及四个蜱种（ 和 ）。鉴定出的血液寄生虫是 。在风险因素中，发现体况评分和年份季节与蜱虫感染显著相关，在95%置信区间下，分别为 = 9.919， > 0.05和 = 6.216， > 0.05。发现蜱虫感染与血虫血症显著相关，在95%置信区间下， = 22.2， > 0.05。本研究的结果敲响了警钟，因为兽医服务在潜在的鉴别诊断清单中一直未考虑任何血虫血症，也未为此提供任何治疗方法。因此，建议该地区的兽医服务提供系统应进行血液寄生虫诊断并提供治疗选择，特别是针对蜱传疾病。此外，在蜱传疾病流行之前，该地区应采取战略方法控制蜱传疾病，因为在粗放式家畜管理中，疾病高发后进行控制并非易事。
