anisakiasis

[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·sa·ki·a·sis

(an'i-să-kī'ă-sis),

Infection of the intestinal wall by larvae of Anisakis marina and other genera of anisakid nematodes (Contracaecum, Phocanema), characterized by intestinal eosinophilic granuloma and symptoms resembling those of peptic ulcer or tumor.

Synonym(s): herring-worm disease

anisakiasis

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 (e.g., 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 findings
A simplex (abdominal pain, nausea, vomiting, diarrhoea) eosinophilia with occult blood in stool if gastric anisakiasis; leukocytosis without eosinophilia if intestinal anisakiasis.

P decipiens
Few significant symptoms, as it does not penetrate gastric or intestinal wall.

Management gastric anisakiasis
Endoscopic removal of larva.

Management intestinal anisakiasis
Surgical excision of involved intestine.

anisakiasis

Herring worm disease caused by the larvae of worms of the Anisakidae family. A parasitic infection acquired by eating raw herrings. A fibrous mass (granuloma) forms in the intestine causing fever, colic and intermittent obstruction. Surgical treatment may be needed.
