The Life Cycle of Anisakis simplex: A Review



Anisakis simplex (Rudolphi, 1809, det. Krabbe, 1878) in its larval stage is a common nematode parasite of marine fish, with the adult parasite widely distributed in marine mammals, particularly in colder temperate and polar waters [1].This parasite causes eosinophilic granuloma in the alimentary tract of man when raw or inadequately cooked fish with live larvae are ingested [2,3]. To determine its medical significance with regard to human infection, called “anisakiasis” or “anisakiosis”, various aspects of the parasite have been studied to date. This review focuses on the life cycle of A. simplex (Fig. 1), based on information from surveys which were conducted mainly in the North Pacific Ocean and North Sea.
