is a zoonotic nematode traditionally detected worldwide in both domestic and wild animals. In South America, along with the occurrence of this parasite in domestic pigs and wild boars, there are reports of infection in wild carnivores. Brazil is considered free of the domestic cycle of , but there is unpublished serological evidence of infection in wild boars, which changed the Brazilian status in OIE regarding the disease after an official communication. We investigated spp. infection in wild boars and wild carnivores in the Southeastern region of Brazil. A total of 136 samples were tested, 121 from wild boars and 15 from wild carnivores. Artificial enzymatic digestion (AED) tests were performed on muscle samples from 37 wild boars and 15 wild carnivores, and 115 serum samples from wild boars were tested by iELISA. Seven serum samples from wild boars tested positive (7/115 = 6.1%, 95% CI 3.0-12.0), but no larvae were found in the AED. There was no significant difference between sex, age, and location of the samples. The serological results suggest that a wild cycle of spp. may occur in Brazil, but further analyses should be performed to confirm the presence of the parasite.
是一种人畜共患的线虫，传统上在全球范围内的家畜和野生动物中均可检测到。在南美洲，随着这种寄生虫在家猪和野猪中出现，也有野生食肉动物感染的报告。巴西被认为没有该寄生虫的家畜传播循环，但有未发表的野猪感染血清学证据，在一次官方通报后，这改变了巴西在世界动物卫生组织（OIE）中关于该疾病的状况。我们调查了巴西东南部地区野猪和野生食肉动物的 spp. 感染情况。共检测了136份样本，其中121份来自野猪，15份来自野生食肉动物。对37头野猪和15只野生食肉动物的肌肉样本进行了人工酶消化（AED）检测，并用间接酶联免疫吸附测定法（iELISA）检测了115份野猪血清样本。7份野猪血清样本检测呈阳性（7/115 = 6.1%，95%置信区间3.0 - 12.0），但在AED检测中未发现幼虫。样本的性别、年龄和地点之间没有显著差异。血清学结果表明，巴西可能存在 spp. 的野生传播循环，但应进行进一步分析以确认寄生虫的存在。
