Abstract：
A systematic review and meta-analysis were performed to identify the global prevalence and factors associated with Toxoplasma gondii infection in wild birds. Six bibliographic databases (Chinese National Knowledge Infrastructure, VIP Chinese Journal Database, Wanfang Data, PubMed, Web of science and ScienceDirect) were searched from inception to February 2023. The search yielded 1220 records of which 659 articles underwent full-text evaluation, which identified 49 eligible articles and 16,030 wild bird samples that were included in the meta-analysis. The estimated pooled global prevalence of T. gondii infection in wild birds was 16.6%. Out of the variables tested, publication year after 2020 and climate type were significantly associated with T. gondii infection (P<0.01). Our data indicate that the prevalence of T. gondii in wild birds can be influenced by epidemiological variables. Further research is needed to identify the biological, environmental, anthropogenic, and geographical risk factors which impact the ecology and prevalence of T. gondii in wild birds.
摘要：
进行了系统评价和荟萃分析，以确定野生鸟类弓形虫感染的全球患病率和相关因素。六个书目数据库(中国国家知识基础设施，VIP中国期刊数据库,万方数据,PubMed,Webofscience和ScienceDirect)从成立之初到2023年2月进行了搜索。搜索产生了1220条记录，其中659篇文章进行了全文评估，该研究确定了纳入荟萃分析的49篇合格文章和16,030份野鸟样本。估计全球野生鸟类弓形虫感染的汇总患病率为16.6％。在测试的变量中，2020年以后发表，气候类型与弓形虫感染显着相关（P<0.01）。我们的数据表明，野生鸟类中弓形虫的患病率可能受到流行病学变量的影响。需要进一步的研究来确定生物，环境,人为的,以及影响野生鸟类弓形虫生态和流行的地理风险因素。
