, the largest South American canid, is a native species of the Brazilian cerrado. The present study is aimed to report the occurrence of the trematode, , in the liver of a new host, , and to describe its morphology and pathology. One individual was necropsied and examined for the presence of parasites. Worms were collected from the bile ducts and based on morphological and morphometrical characteristics, such as a relatively large, slender, aspinose, elongated shape with vitellarium present on the upper left side of the body were identified as . On the host, hepatic lesions limited to the bile ducts and periportal regions, were characterized as chronic-active cholangitis, biliary hyperplasia, and fibrosis . This is the first report of parasitizing , demonstrating that this parasite has no host specificity and can be widely distributed. lesions noted in are similar to those noted in various other mammalian hosts.
南美最大的犬科动物，是巴西塞拉多的本土物种。本研究旨在报告一种吸虫在新宿主肝脏中的出现情况，并描述其形态和病理学特征。对一只个体进行了尸检以检查寄生虫的存在。从胆管中收集到蠕虫，根据形态和形态测量特征，如相对较大、细长、无棘、呈细长形且卵黄腺位于身体左侧上方，将其鉴定为[吸虫名称]。在宿主体内，局限于胆管和门静脉周围区域的肝脏病变表现为慢性活动性胆管炎、胆管增生和纤维化。这是[吸虫名称]寄生[宿主名称]的首次报告，表明这种寄生虫没有宿主特异性，并且可以广泛分布。在[宿主名称]中发现的病变与在其他各种哺乳动物宿主中发现的病变相似。
