Ticks and tick-borne pathogens are the main challenge to livestock production and productivity in sub-Saharan Africa, particularly in Ethiopia, where favorable conditions exist for the activity of various parasites due to its geographical location, climate, and biological and cultural characteristics. This study was to provide pooled estimates for individually available data on ixodid ticks, their trend comparisons, and ixodid tick grouping among cattle in Ethiopia. Cochrane's Q, , sensitivity analysis, funnel plot, Begg, and Egger regression tests were used to check heterogeneity and publication bias. A random effect model was used to calculate the pooled magnitude of ixodid ticks among cattle. A total of 17,161 cattle from 41 studies were included. The pooled prevalence of ixodid ticks among cattle was 64.42% (95% CI = 57.13-71.71). A total of 82,804 adult ticks belonging to three different genera of ixodid ticks, namely () (47.53%), (46.10%), and (6.37%), were recorded from the included studies. The general trend for the prevalence of ixodid tick infestation among cattle has decreased, from 68.65% in 2010-2015 to 60.13% in 2021-2023. In the present scenario, ixodid tick infestation range from 59.21 to 89.58% and are higher in Gambella region.
蜱虫及其传播的病原体是撒哈拉以南非洲地区畜牧业生产和生产力面临的主要挑战，在埃塞俄比亚尤为如此。由于其地理位置、气候以及生物和文化特征，该国存在各种寄生虫活跃的有利条件。本研究旨在提供埃塞俄比亚牛身上硬蜱的个体可用数据的汇总估计、趋势比较以及硬蜱分组情况。使用Cochrane's Q检验、敏感性分析、漏斗图、Begg检验和Egger回归检验来检查异质性和发表偏倚。采用随机效应模型计算牛身上硬蜱的汇总数量。总共纳入了来自41项研究的17161头牛。牛身上硬蜱的汇总感染率为64.42%（95%置信区间=57.13 - 71.71）。从纳入的研究中记录到总共82804只属于三个不同硬蜱属的成年蜱虫，即（）（47.53%）、（46.10%）和（6.37%）。牛身上硬蜱感染率的总体趋势有所下降，从2010 - 2015年的68.65%降至2021 - 2023年的60.13%。在当前情况下，硬蜱感染率在59.21%至89.58%之间，在甘贝拉地区更高。
