Abstract：
Echinococcus species (spp.) are regarded as neglected cestodes causing several potential zoonoses of global public health. This systematic review critically appraises the worldwide distribution of Echinococcus spp. and genotypes (Echinococcus spp.: recognized species in the genus; genotypes: variants identified within E. granulosus sensu lato.) in definitive hosts. We analyzed 82 studies from major databases, comprising 24 individual host species, including canids, felids, and a hyenid species. Canids, particularly dogs, were the most studied group among the host species, with E. granulosus sensu stricto (G1-G3) being the most frequently reported. E. granulosus s.s. was distributed across five major continents, while other Echinococcus spp. and genotypes exhibited an uneven continental distribution. The highest overlap of species existed among Asia, Europe, and Africa. Among the reported host species, 4.2 % were endangered (e.g. Lycaon pictus), 12.5 % species were vulnerable (e.g. Panthera leo, Panthera pardus, and Acinonyx jubatus), and 4.2 % were near threatened (e.g. Speothos venaticus). Overall, our review highlights the significance of canids, particularly dogs, as the core focus of scientific investigations, with E. granulosus s.s. being the most widely distributed species across five major continents, emphasizing the urgent need for continued research and public health efforts.
摘要：
棘球蚴物种（spp。)被认为是被忽视的昆虫，导致全球公共卫生的几种潜在人畜共患病。本系统综述严格评估了棘球蚴的全球分布。和基因型（棘球蚴属。：属中的公认物种；基因型：在S.granulosussensulato中鉴定出的变体。)在确定的主机中。我们分析了来自主要数据库的82项研究，由24个个体宿主物种组成，包括犬科动物,Felids,和一个犬科动物。犬科动物,尤其是狗,是寄主物种中研究最多的群体，其中最常报道的是细粒E.grulosussensustricto（G1-G3）。E.granulosuss.s.分布在五大洲，而其他棘球蚴属。基因型表现出不均匀的大陆分布。亚洲物种重叠程度最高，欧洲,和非洲。在报告的宿主物种中，4.2%的人濒临灭绝(例如Lycaonpictus)，12.5%的物种是脆弱的(例如板南鱼，PantheraPardus,和Acinonyxjubatus)，4.2%的人濒临灭绝(例如Speothosvenaticus)。总的来说,我们的评论强调了犬科动物的重要性，尤其是狗,作为科学研究的核心焦点，E.granulosuss.s.是五大洲分布最广的物种，强调迫切需要继续研究和公共卫生工作。
