anisakiasis

anisakiasis /an·i·sa·ki·a·sis/ (an″ĭ-sah-ki´ah-sis) infection with the third-stage larvae of the roundworm Anisakis marina, which burrow into the stomach wall, producing an eosinophilic granulomatous mass. Infection is acquired by eating undercooked marine fish.

[an′i·sə·kī′ə·sis]

infection of humans or other animals with a nematode of the family Anisakidae, usually Anisakis marina. Human infection is usually caused by third-stage larvae eaten in sushi and undercooked infected marine fish such as herring. The larvae then burrow into the stomach wall, producing an eosinophilic granulomatous mass. The infection is distributed worldwide, but occurs with higher incidence in places where raw fish is consumed, such as Japan. Also called eosinophilic granuloma.

anisakiasis

Parasitology Infestation of the upper GI tract–stomach, small intestine mucosae by larvae of the family Anisakidae, which are common ascaroid parasites of marine fish; human infestation results from eating raw fish–eg, sushi; the larval stage of Anisakis simplex and Phocanema–Pseudoterranova decipiens account for all US cases of anisakiasis; another anasakine, Contracecum, may rarely cause anisakiasis Clinical A simplex–abdominal pain, N&V, diarrhea, eosinophilia with occult blood in stool, if gastric anisakiasis; leukocytosis sans eosinophilia if intestinal anisakiasis; P decipiens—few significant Sx, as it does not penetrate gastric or intestinal wall Management-gastric anisakiasis–endoscopic removal of larva Intestinal anisakiasis–surgical excision of involved intestine. See Sushi.
