Although previous studies have characterized the helminth fauna of wild boars kept in captivity in Brazil, records on these helminths in free-ranging animals are still scarce. In view of this, we aimed in our work to investigate the occurrence and morphological and morphometric characteristics of gastrointestinal helminths in wild Sus scrofa from the northwest region of the State of São Paulo, Brazil. The digestive systems of 10 animals (5 males and 5 females of different ages) were used in this study. Each anatomical segment was washed and sieved under running water, and the helminths were separated and identified using light and scanning electron microscopy, according to their morphological characteristics. A total of 2750 (1152 males and 1598 females) nematode specimens were collected from the small intestine of these wild boars, and all of them presented the morphological characteristics of . However, one characteristic is of particular interest because it has not yet been reported in the literature: a marked asymmetry between the lobes and their respective rays of the copulatory bursa, with the left one being larger than the right one. In this research, we identified the presence of in all the examined free-ranging wild boars and reported for the first time in the literature the asymmetry in the copulatory bursa.
尽管先前的研究已经对巴西圈养野猪的蠕虫动物区系进行了特征描述，但关于这些蠕虫在自由放养动物中的记录仍然很少。鉴于此，我们在工作中旨在调查巴西圣保罗州西北部地区野生野猪胃肠道蠕虫的发生情况以及形态和形态计量学特征。本研究使用了10只动物（5只不同年龄的雄性和5只雌性）的消化系统。每个解剖段在流水下冲洗和筛分，然后根据蠕虫的形态特征，使用光学显微镜和扫描电子显微镜对其进行分离和鉴定。从这些野猪的小肠中总共收集了2750条线虫标本（1152条雄性和1598条雌性），所有标本都呈现出[具体线虫种类未给出]的形态特征。然而，有一个特征特别值得关注，因为它尚未在文献中报道：交配囊的叶及其各自的射线之间存在明显的不对称，左侧大于右侧。在本研究中，我们在所有检查的自由放养野生野猪中都发现了[具体线虫种类未给出]的存在，并在文献中首次报道了交配囊的不对称性。
