| description, microhabitat selection and infection patterns of sealworm larvae (pseudoterranova decipiens species complex, nematoda: ascaridoidea) in fishes from patagonia, argentina. | third-stage larvae of the pseudoterranova decipiens species complex (also known as sealworms) have been reported in at least 40 marine fish species belonging to 21 families and 10 orders along the south american coast. sealworms are a cause for concern because they can infect humans who consume raw or undercooked fish. however, despite their economic and zoonotic importance, morphological and molecular characterization of species of pseudoterranova in south america is still scarce. | 2013 | 23988009 |
