Ruminant abortion events cause economic losses. Despite the importance of livestock production for food security and the livelihoods of millions of people in the world's poorest communities, very little is known about the scale, magnitude, or causes of these abortions in Africa and Asia. The aim of this review was to determine the current status of surveillance measures adopted for ruminant abortigenic pathogens in Africa and Asia and to explore feasible surveillance technologies. A systematic literature search was conducted using PRISMA guidelines for studies published between 1 January 1990 and 1 May 2024 that reported epidemiological surveys of abortigenic pathogens Africa and Asia. A meta-analysis was used to estimate the species-specific sero-prevalence of the abortigenic agents and the regions where they were detected. In the systematic literature search, 39 full-text manuscripts were included. The most prevalent abortigenic pathogens with sero-prevalence greater than 10% were BHV-1, , RVFV, and in cattle, BVDV in sheep, and RVFV and in goats in Africa. In Asia, Anaplasma, BHV-1, Bluetongue virus, and BVDV were prevalent in cattle, whereas Mycoplasma was important in goats and sheep.
反刍动物流产事件会造成经济损失。尽管畜牧业生产对粮食安全以及世界最贫困社区数百万人的生计至关重要，但对于非洲和亚洲这些流产事件的规模、严重程度或原因却知之甚少。本综述的目的是确定非洲和亚洲针对反刍动物流产病原体所采取的监测措施的现状，并探索可行的监测技术。使用PRISMA指南对1990年1月1日至2024年5月1日期间发表的报告非洲和亚洲流产病原体流行病学调查的研究进行了系统的文献检索。采用荟萃分析来估计流产病原体的物种特异性血清流行率以及检测到这些病原体的地区。在系统的文献检索中，纳入了39篇全文手稿。血清流行率大于10%的最常见流产病原体在非洲的牛中为牛疱疹病毒1型、裂谷热病毒等，在绵羊中为牛病毒性腹泻病毒，在山羊中为裂谷热病毒等。在亚洲，无浆体属、牛疱疹病毒1型、蓝舌病毒等在牛中流行，而支原体在山羊和绵羊中较为重要。
