Ring-tailed Lemur () is the only surviving semi-terrestrial diurnal lemur in Madagascar. Despite being the most intensively studied of lemur taxa, only a few helminths have been described in this species. In this study we describe a persistent infection due to in a captive population of hosted in a zoological park of northern Italy. In the context of a parasitological survey on zoo animals, we investigated parasites in a captive colony of ring-tailed lemurs within a zoological park. Parasitological analysis included necropsy of a deceased lemur in 2019, subsequent fecal sample collections in 2021-2022, followed by coprological examination and coprocolture. Morphological and molecular analyses were conducted on adult helminths, larvae and eggs, involving microscopy, scanning electron microscopy (SEM), and sequencing of the ITS rDNA region. Trichostrongylidae parasites were primarily found after necropsy in the intestine of the lemur. Morphological and molecular investigations on adults and eggs/larvae recovered from feces collected at different times from lemurs of the same captive population, allowed to properly identify the parasite as . . To the best of our knowledge this is the first description of in . Although its presence in wild populations is not necessarily implied by our finding, this parasitosis represent a cause of concern in captive lemurs, considering the possibility of interspecies transmission and the zoonotic implications.
环尾狐猴（）是马达加斯加唯一现存的半陆生昼行性狐猴。尽管它是狐猴类群中研究最深入的物种，但该物种中仅描述了少数几种寄生虫。在本研究中，我们描述了意大利北部一家动物园圈养的环尾狐猴种群中由[寄生虫名称未给出]引起的持续性感染。在对动物园动物进行寄生虫学调查的背景下，我们调查了一家动物园内圈养的环尾狐猴种群中的寄生虫。寄生虫学分析包括2019年对一只死亡狐猴的尸检、随后在2021 - 2022年收集粪便样本，接着进行粪便学检查和粪便培养。对成虫、幼虫和虫卵进行了形态学和分子分析，包括显微镜检查、扫描电子显微镜（SEM）以及ITS rDNA区域测序。毛圆科寄生虫主要在尸检时在狐猴的肠道中发现。对从同一圈养种群的狐猴在不同时间收集的粪便中回收的成虫和虫卵/幼虫进行的形态学和分子研究，使我们能够正确地将寄生虫鉴定为[寄生虫名称未给出]。据我们所知，这是[寄生虫名称未给出]在环尾狐猴中的首次描述。尽管我们的发现不一定意味着其在野生种群中的存在，但考虑到种间传播的可能性和人畜共患病的影响，这种寄生虫病在圈养狐猴中是一个令人担忧的问题。
