The study describes the occurrence of cysticercosis in liver of 22 wild agoutis (Dasyprocta leporina) in the Brazilian Amazon. The phylogenetic analysis and microscopic characteristics of metacestodes in liver tissue sections, associated with the geographic distribution of the intermediate hosts indicated that a possibly novel Taenia sp. metacestode caused the parasitism. Additionally, two cases of hepatic co-infection by Taenia sp., Calodium sp. and Echinococcus oligarthra were also observed among the analyzed animals. The results point to the need for a better understanding of hepatotropic parasites among wild rodents in the Brazilian Amazon.
本研究描述了在巴西亚马逊地区的 22 只野生毛丝鼠肝脏中囊尾蚴的发生情况。对肝组织切片中囊尾蚴的系统发育分析和微观特征，以及中间宿主的地理分布表明，可能是一种新的带绦虫属的囊尾蚴导致了这种寄生虫感染。此外，在分析的动物中还观察到两种由带绦虫、Calodium sp. 和 Echinococcus oligarthra 引起的肝脏合并感染病例。这些结果表明，有必要更好地了解巴西亚马逊地区野生啮齿动物中的肝寄生虫。
