ABSTRACT

Resumen La anisakidosis es una zoonosis parasitaria accidental y cosmopolita de los seres humanos, siendo su hospedero definitivo los mamíferos marinos como lobos de mar, focas y delfines, entre otros. El ser humano se infecta por el consumo en estado larvario del nemátodo de la familia Anisakidae presentes en pescados y mariscos crudos como la merluza o el congrio. Los helmintos se ubican preferentemente en el tubo digestivo alto, observándose la regurgitación del parásito a la boca o evidenciándose durante la realización de una endoscopía digestiva alta. En forma infrecuente las larvas pueden migrar al peritoneo o seguir su paso por el intestino delgado y colon, siendo inhabitual la expulsión por las deposiciones. Presentamos el caso de una expulsión dos larvas L3 de la familia Anisakidae en deposiciones.


Abstract 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.
