() is a significant protozoan pathogen among food animals. Despite the threat to public health by infections, there's limited understanding of its seroprevalence and trends in food animals across mainland China. This study aimed to estimate the seroprevalence of infections among swine, sheep, goats, chickens, and cattle in mainland China from 2010 to 2023.
We searched cross-sectional studies published between 2010 and 2023 that reported the prevalence of in food animals from databases including PubMed, Embase, Web of Science, China Biology Medicine Disc (CBM), China National Knowledge Infrastructure (CNKI), Wanfang data, and the China Science and Technology Journal Database (CQVIP). We performed subgroup analyses to explore the impact of different factors on the seroprevalence of . Pooled estimates of seroprevalence were calculated with a random-effects model.
An analysis of 184 studies involving 211985 animals revealed a overall seroprevalence of 15.3% (95% CI: 13.1-17.8). Although the seroprevalence of food animals across mainland China was relatively stable from 2010 to 2023, notable variations were observed across different animal types and regions ( < 0.01), along with changes in geographical distribution. Sample type, detection method, animal age, and history of abortion were identified as key risk factors for seroprevalence.
The study conducted a meta-analysis on the seroprevalence of in mainland China's Food Animals from 2010 to 2023, and identified key risk factors. These findings advance our understanding of infection dynamics, offering critical insights for developing control strategies and guiding public health policies.
（）是食源性动物中的一种重要原生动物病原体。尽管（）感染对公共卫生构成威胁，但对于中国大陆食源性动物中的感染血清流行率和趋势，我们的了解有限。本研究旨在估计 2010 年至 2023 年间中国大陆猪、羊、山羊、鸡和牛中（）感染的血清流行率。
我们从包括 PubMed、Embase、Web of Science、中国生物医学文献数据库（CBM）、中国知网（CNKI）、万方数据和中国科技期刊数据库（CQVIP）在内的数据库中搜索了 2010 年至 2023 年期间发表的横断面研究，这些研究报告了食源性动物中（）的流行率。我们进行了亚组分析，以探讨不同因素对（）血清流行率的影响。采用随机效应模型计算（）血清流行率的汇总估计值。
对涉及 211985 只动物的 184 项研究进行分析，发现总体血清流行率为 15.3%（95%CI：13.1-17.8）。尽管中国大陆的食源性动物血清流行率从 2010 年到 2023 年相对稳定，但不同动物类型和地区之间存在显著差异（<0.01），同时地理分布也发生了变化。样本类型、检测方法、动物年龄和流产史被确定为（）血清流行率的关键风险因素。
本研究对 2010 年至 2023 年间中国大陆食源性动物中（）的血清流行率进行了荟萃分析，并确定了关键风险因素。这些发现提高了我们对（）感染动态的认识，为制定控制策略和指导公共卫生政策提供了重要信息。
