An important method to diagnose and study the helminthofauna of wild animals is to examine the host's feces to find eggs and larvae, seeking to identify the parasites and study their morphobiology. The objective of the present work is to provide morphological and biometric data on the eggs and larvae of Strongyloides sp., a capybara gastrointestinal parasite. Using the technique of Gordon and Whitlock, simple flotation and the modified Baermann examination, capybara fecal samples were selected based on a criterion of the highest proportion of eggs and larvae in the initial development stages, for morphometric description of eggs, L1, L2 and L3 of Strongyloides sp. From past reports of parasitism in Hydrochaeris hydrochaeris, we suspect that the eggs and larvae in this study are of Strongyloides chapini Sandground, 1925, which constitutes the first description of these stages for this species of nematode. Nevertheless, the morphology and biometry data of these stages demonstrate that they are similar to those of other species of the Strongyloides genus.
诊断和研究野生动物蠕虫区系的一种重要方法是检查宿主粪便，以发现虫卵和幼虫，从而识别寄生虫并研究其形态生物学。本研究的目的是提供关于水豚胃肠道寄生虫类圆线虫属虫卵和幼虫的形态学和生物测量数据。采用戈登和惠特洛克技术、简单浮选法以及改良贝曼氏检查法，根据虫卵和处于初始发育阶段幼虫比例最高的标准选择水豚粪便样本，用于类圆线虫属虫卵、第一期幼虫（L1）、第二期幼虫（L2）和第三期幼虫（L3）的形态测量描述。从过去有关水豚寄生虫感染的报告中，我们怀疑本研究中的虫卵和幼虫属于1925年桑德格伦描述的查平类圆线虫，这是该线虫物种这些阶段的首次描述。然而，这些阶段的形态学和生物测量数据表明，它们与类圆线虫属其他物种的相似。
