Descripción
Human anisakidosis is caused by the ingestion of anisakid third-stage larvae of the genera Anisakis, Pseudoterranova, Contracaecum, and Hysterothylacium, present in raw or undercooked fish and shellfish. The members of the complex Anisakis simplex, followed by those of the Pseudoterranova decipiens complex, are the most common anisakids infecting humans. In Argentina, infective larvae of these nematode species, have been identified in marine and freshwater fish. However, there are few human cases of anisakidosis from which the involved species, has not been documented yet. In this study, we reported the detection of anisakids in food and clinical samples from patients of Argentina. Nine samples of larvae were analyzed: two from clinical samples removed orally by patients, and seven found in raw, undercooked and cooked fish. The larvae from the two clinical samples were identified as Pseudoteranova cattani whereas larvae of Anisakis pegreffii, Anisakis sp., and P. cattani were found in food.

En Argentina, se han identificado larvas infectivas de estas especies de nematodes en peces marinos y de agua dulce, sin embargo, existen muy pocos casos descriptos de anisakidosis humana, en los cuales las especies involucradas no han sido documentadas. En este estudio, informamos la detección de anisákidos en alimentos y en muestras clínicas humanas de Argentina. Se analizaron nueve muestras: dos muestras clínicas de larvas eliminadas por pacientes por vía oral y siete muestras de alimentos con larvas encontradas en pescado crudo, poco cocido o cocido. Las larvas de las dos muestras clínicas fueron identificadas como Pseudoteranova cattani mientras que en las de alimentos, se hallaron larvas de Anisakis pegreffii, Anisakis sp. y P. cattani.
