Population Genetic Structure of Anisakis simplex Infecting the European Hake from North East Atlantic Fishing Grounds
The European hake, one of the most commercially valuable species in ICES fishing areas, is considered an important neglected source of zoonotic risk by nematode parasites belonging to the genus Anisakis . Merluccius merluccius is, by far, the most important host of Anisakis spp. at the European fish...
