Abstract

Among the Nematodes of Cerdocyon thous, the genus Pterygodermatites is characteristic for presenting cuticular projections along the body, being mentioned in different hosts in South America, although there are no records of its occurrence in the Amazon Biome. To enable further exploration in terms of their morphology and morphometry, the nematodes collected from cadavers of C. thous were fixed and observed using bright field microscopy and scanning electron microscopy, revealing characteristics compatible with P. (Multipectines) affinis, thus contributing more information about the geographic distribution of the parasite, as well as knowledge of the helminthological fauna of wild mammals in the Brazilian Amazon.

摘要

在食蟹狐的线虫中，翼皮线虫属的特征是身体上有表皮突起，在南美洲的不同宿主中都有提及，尽管在亚马逊生物群落中没有其出现的记录。为了能够进一步探索它们的形态和形态测量学，从食蟹狐尸体上收集的线虫被固定，并使用明场显微镜和扫描电子显微镜进行观察，结果显示出与亲缘翼皮线虫（多栉亚种）相符的特征，从而为该寄生虫的地理分布以及巴西亚马逊地区野生哺乳动物的蠕虫动物区系知识提供了更多信息。
