Abstract

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, I², 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 Rhipicephalus (Boophilus) (47.53%), Amblyomma (46.10%), and Hyalomma (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.

埃塞俄比亚牛群中蜱虫（Acari: Ixodoidea）的流行率、趋势比较和鉴定：系统回顾与荟萃分析

蜱虫和蜱虫传播的病原体是撒哈拉以南非洲地区牲畜生产和生产力面临的主要挑战，尤其是在埃塞俄比亚，由于其地理位置、气候以及生物和文化特征，这里为各种寄生虫的活动提供了有利条件。这项研究的目的是对埃塞俄比亚牛群中现有的牛蜱数据、趋势比较以及牛蜱分组情况进行汇总估算。研究采用 Cochrane Q、I2、敏感性分析、漏斗图、Begg 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了牛群中伊科蜱的总体数量。共纳入了 41 项研究中的 17 161 头牛。牛群中蜱虫的总体流行率为 64.42% (95% CI = 57.13-71.71)。所纳入的研究共记录了82 804只成蜱，分别隶属于三种不同的蜱属，即Rhipicephalus (Boophilus) (47.53%)、Amblyomma (46.10%)和Hyalomma (6.37%)。牛群中的蜱虫感染率总体呈下降趋势，从 2010-2015 年的 68.65% 降至 2021-2023 年的 60.13%。目前，牛虱感染率在 59.21% 至 89.58% 之间，甘贝拉地区的感染率较高。

期刊介绍： Parasite Epidemiology and Control is an Open Access journal. There is an increasing amount of research in the parasitology area that analyses the patterns, causes, and effects of health and disease conditions in defined populations. This epidemiology of parasite infectious diseases is predominantly studied in human populations but also spans other major hosts of parasitic infections and as such this journal will have a broad remit. We will focus on the major areas of epidemiological study including disease etiology, disease surveillance, drug resistance and geographical spread and screening, biomonitoring, and comparisons of treatment effects in clinical trials for both human and other animals. We will also look at the epidemiology and control of vector insects. The journal will also cover the use of geographic information systems (Epi-GIS) for epidemiological surveillance which is a rapidly growing area of research in infectious diseases. Molecular epidemiological approaches are also particularly encouraged.
