摘要

蜱是牛最主要的体外寄生虫，造成重大损失。从2024年3月至5月，在埃塞俄比亚奥罗米亚地区西谢瓦区Guder镇及其周围进行了一项横断面研究，以确定感染牛的伊蚊蜱的种类，并估计其流行率和相关危险因素。采用系统随机抽样的方法，采集了200头牛的成年蜱，并用体视显微镜对其形态进行了分类。在检查的牛中，75.0% （95% CI: 68.5-80.6）感染了一种或多种蜱虫。蜱虫感染率最高的是马莫·梅兹米尔·凯贝勒、公牛、幼牛、粗放型管理系统和体况良好的牛，分别为94.7%、87.5%、86.7%、77.6%和80.0%。经鉴定，蜱属有羊蜱、鼻头蜱、透明蜱和鼻头蜱4属。共采集蜱虫702只。蜱种数量最多（38.7%）的是疣鼻头蜱，最少（8.1%）的是斑纹透明眼蜱。农会和性别是影响蜱虫侵害的唯一危险因素（p < 0.05）。Mamo Mezemir kebele地区的牛被蜱虫感染的可能性是其他地区的17倍（OR = 16.9; 95% CI: 1.9-149.2）。这项研究表明，蜱虫是研究地区牛最关心的问题。因此，建议采取战略控制蜱虫，其中包括使用杀螨剂，并提高牲畜所有者对蜱虫侵扰影响的认识。

Distribution of ixodid ticks of cattle and associated risk factors in and around Guder town, west Shewa zone, Oromia, Ethiopia

Ticks are the most prominent ectoparasites of cattle, causing significant losses. From March to May 2024, a cross-sectional study was carried out in and around Guder town of the west Shewa zone of the Oromia region, Ethiopia, to identify species of ixodid ticks infesting cattle and estimate their prevalence and associated risk factors. Adult ixodid ticks were collected from 200 cattle using systematic random sampling methods and classified into species based on their morphology using a stereomicroscope. Of the examined cattle, 75.0 % (95 % CI: 68.5–80.6) were infested with one or more tick species. The highest prevalence of tick parasites was recorded in Mamo Mezemir kebele, male, young, extensive management system, and good-body condition of cattle, with prevalences of 94.7 %, 87.5 %, 86.7 %, 77.6 %, and 80.0 %, respectively compared to counterparts. Four genera of ticks were identified viz. Amblyomma, Rhipicephalus (Boophilus), Hyalomma, and Rhipicephalus. A total of 702 ticks were collected. Rhipicephalus evertsi evertsi and Hyalomma rufipes were the most (38.7 %) and least (8.1 %) abundant tick species, respectively. The peasant associations and sex were the only risk factors associated with the tick infestations (p < 0.05). Cattle in the Mamo Mezemir kebele were 17 (OR = 16.9; 95 %CI: 1.9–149.2) times more likely to be infested by ticks than those in other regions. This study shows that ticks were a most significant concern for cattle in the studied area. Thus, strategic tick control, which includes the use of acaricides, and creating awareness for the livestock owners about the impact of tick infestation is recommended.

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.
