In the Qinghai-Tibet Plateau of China, the yak is an animal of particular economic interest, which provides protein and income for herders in daily life. Brucellosis is a bacterial disease that can infect humans and animals, including yaks. It can damage the yak reproductive system, causing miscarriage and orchitis. At the same time, brucellosis threatens the health of herders. We performed this meta-analysis using R software to explore the combined prevalence and risk factors of brucellosis in yak in China. Variability was assessed by the I statistic and Cochran Q statistic. We identified 52 publications of related research from four databases (Wanfang Data, VIP Chinese Journal Database, China National Knowledge Infrastructure, and of PubMed). The pooled prevalence of yak brucellosis was 8.39 %. Prevalence was highest in Southwestern China (11.1 %). The point estimate of brucellosis in yak from 2012 to 2016 was the highest (11.47 %). The point estimate of age ≤ 12 months (1.44 %) was lower than that of age > 12 months (15.6 %). This study shows that yak brucellosis is serious, and its incidence is higher than before 2012. We recommend carrying out large-scale yak brucellosis investigations in Western China and conducting comprehensive testing planning. The detection of brucellosis in adult animals should be strengthened to reduce the economic loss caused by brucellosis to herders and to improve public health.
在中国的青藏高原，牦牛是一种具有特殊经济利益的动物，它为牧民的日常生活提供了蛋白质和收入。布鲁氏菌病是一种可以感染人类和动物的细菌病，包括牦牛。它可以损害牦牛的生殖系统，导致流产和睾丸炎。同时，布鲁氏菌病威胁着牧民的健康。我们使用 R 软件进行了这项荟萃分析，以探讨中国牦牛布鲁氏菌病的综合流行率和危险因素。用 I 统计和 Cochran Q 统计来评估变异性。我们从四个数据库（万方数据、维普中文期刊数据库、中国知网和 PubMed）中确定了 52 篇相关研究的出版物。牦牛布鲁氏菌病的总流行率为 8.39%。中国西南部的流行率最高（11.1%）。2012 年至 2016 年牦牛布鲁氏菌病的点估计值最高（11.47%）。年龄≤12 个月（1.44%）的点估计值低于年龄>12 个月（15.6%）。本研究表明，牦牛布鲁氏菌病很严重，其发病率高于 2012 年之前。我们建议在中国西部开展大规模的牦牛布鲁氏菌病调查，并进行全面的检测规划。应加强对成年动物布鲁氏菌病的检测，以减少布鲁氏菌病给牧民带来的经济损失，改善公众健康。
