Abstract

The Neotropical Nannopterum brasilianus is a piscivorous bird feeding on aquatic organisms, can ingest various infectious forms of helminths, such as those from the phylum Acanthocephala. In their adult stage, these parasites attach to the intestinal mucosa of their definitive hosts, causing varying degrees of tissue damage. Between 2020 and 2023, 35 individuals of N. brasilianus were analyzed, and 20 of them (57.1%) presented acanthocephalan infection. Morphological and histopathological analyses identified the species as Southwellina hispida, we described the tissue alterations associated with its presence in detail. The results contribute to the taxonomic knowledge of the parasite and provide important information for diagnosing and monitoring of infections in birds housed at Wildlife Triage and Rehabilitation Centers (WTRC).

源海洋提取保护区巴西南翅虫多态科（棘头科）宿主-寄生虫关系的研究

新热带巴西南翅虫是一种以水生生物为食的鱼食性鸟类，可以摄入各种传染性形式的蠕虫，例如棘头虫门的蠕虫。在它们的成虫阶段，这些寄生虫附着在它们最终宿主的肠黏膜上，造成不同程度的组织损伤。2020 - 2023年共采集35只巴西蠓，其中20只（57.1%）感染棘头绦虫。形态学和组织病理学分析确定该物种为南wellina hispida，我们详细描述了与它的存在相关的组织改变。该结果有助于对寄生虫的分类认识，并为野生动物分类和康复中心（WTRC）饲养的鸟类的感染诊断和监测提供重要信息。

期刊介绍： The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
