Occurrence of Terranova larval types (Nematoda: Anisakidae) in Australian marine fish with comments on their specific identities
Pseudoterranovosis is a well-known human disease caused by anisakid larvae belonging to the genus Pseudoterranova. Human infection occurs after consuming infected fish. Hence the presence of Pseudoterranova larvae in the flesh of the fish can cause serious losses and problems for the seafood, fishin...
