The first determination of Eustrongylides excisus Jagerskiold, 1909 - larvae (Nematoda: Dioctophymatidae) in the pike-perch Sander lucioperca in Vojvodina (Serbia).

摘要

Twenty-one specimens of pike-perch (Sander lucioperca) were caught in the Danube-Tisa-Danube Canal in the city area of Novi Sad for parasitological examination. The presence of nematodes in the muscles was revealed in three fish. The parasites were identified to belong to the species Eustrongylides excisus, for which the pike-perch is a paratenic host. This finding represents the first determination of the larvae in the pike-perch in Serbia. The pike-perch is infected by ingestion of benthos- or plankton-eating fishes, the second intermediate hosts harbouring the fourth-stage nematode larvae. E. excisus is pathogenic to humans, who may be infected by consuming raw or undercooked fish.
