An·i·sa·kis (an″ĭ-saґkis) [Gr. an- + is- + akis point] a genus of nematodes of the family Anisakidae; the usual infecting species is A. mariґna. It parasitizes the stomachs of marine mammals and birds, where it reaches the adult stage. Infective third-stage larvae occur in various marine fishes, and humans who eat raw fish may get anisakiasis.
