Anisakidosis is an accidental and cosmopolitan parasitic zoonosis of human beings, its definitive host being marine mammals such as sea lions, seals and dolphins, among others. Humans are infested by consumption in the larval stage of the nematode of Anisakis present in raw fish and shellfish such as hake or conger eel. The infestation is preferably located in the upper digestive tract, observing the regurgitation of the parasite to the mouth or becoming evident during an upper gastrointestinal endoscopy. In rare cases, the larvae can migrate to the peritoneum or continue their passage through the small intestine and colon, with expulsion in stools being unusual. We present a case of expulsion of two larvae of the Anisakidae family in feces.
异尖线虫病是一种人类偶然感染的世界性寄生虫人畜共患病，其终末宿主为海狮、海豹和海豚等海洋哺乳动物。人类因食用生鱼和贝类（如无须鳕或康吉鳗）中存在的异尖线虫幼虫而受到感染。感染部位多在上消化道，可观察到寄生虫反流至口腔，或在上消化道内镜检查时显现出来。在罕见情况下，幼虫可迁移至腹膜，或继续穿过小肠和结肠，粪便排出幼虫的情况并不常见。我们报告一例粪便中排出两条异尖线虫科幼虫的病例。
