Brucellosis, a neglected and global zoonotic disease, infect a variety of mammals, among which sheep are one of the main hosts. This disease results in huge economic losses and is a widespread concern around the world.
Based on the selection criteria, 40 articles from 2010 to 2021 of five databases (CNKI, Wanfang, VIP, PubMed and Science Direct) reported in America, Africa and Asia were included. The data showed that during this period, the overall seroprevalence of sheep brucellosis on these three continents was 6.2%. At the regional level, sheep brucellosis had the highest seroprevalence (8.5%) in Africa and the lowest seroprevalence (1.9%) in the Americas. With regard to the age of the sheep, the seroprevalence was significantly higher in adult sheep (15.5%) than in lambs (8.6%). Further, the seroprevalence was significantly higher in sheep that had abortion (44.3%) than in pregnant (13.0%) and non-pregnant sheep (9.5%). With regard to herd size, herds with >20 sheep (35.4%) had a significantly higher seroprevalence than herds with <20 sheep (16.8%). In terms of farming and grazing mode, free-range rearing (8.4%) was associated with a significantly higher seroprevalence than intensive farming (2.8%), and mixed grazing (37.0%) was associated with a significantly higher seroprevalence than single grazing (5.7%).
Sheep brucellosis is widely distributed in sheep-rearing regions of America, Africa and Asia, and sheep are susceptible to brucellosis by themselves or from other infectious sources. Therefore, timely monitoring of ovine brucellosis and improving farming and grazing patterns are critical to reducing the prevalence of brucellosis.
布鲁氏菌病是一种被忽视的全球性人畜共患病，可感染多种哺乳动物，其中绵羊是主要宿主之一。这种疾病会导致巨大的经济损失，受到全世界的广泛关注。
根据筛选标准，纳入了2010年至2021年期间来自美国、非洲和亚洲的五个数据库（中国知网、万方、维普、PubMed和Science Direct）报道的40篇文章。数据显示，在此期间，这三大洲绵羊布鲁氏菌病的总体血清阳性率为6.2%。在区域层面，绵羊布鲁氏菌病血清阳性率在非洲最高（8.5%），在美洲最低（1.9%）。关于绵羊的年龄，成年绵羊的血清阳性率（15.5%）显著高于羔羊（8.6%）。此外，流产绵羊的血清阳性率（44.3%）显著高于怀孕绵羊（13.0%）和未怀孕绵羊（9.5%）。关于畜群规模，绵羊数量>20只的畜群血清阳性率（35.4%）显著高于绵羊数量<20只的畜群（16.8%）。在养殖和放牧方式方面，放养（8.4%）的血清阳性率显著高于集约化养殖（2.8%），混合放牧（37.0%）的血清阳性率显著高于单一放牧（5.7%）。
绵羊布鲁氏菌病广泛分布于美洲、非洲和亚洲的养羊地区，绵羊自身或通过其他传染源易感染布鲁氏菌病。因此，及时监测绵羊布鲁氏菌病并改善养殖和放牧模式对于降低布鲁氏菌病的流行率至关重要。
