Eustrongylidosis of european catfish (Siluris glanis)

Abstract

Eustrongylidosis is caused by the nematodes from the genus Eustrongylides, which are parasites of piscivorous birds. Their life cycle require two intermediate hosts, aquatic oligochaetes and benthophagous fish. Human is not a typical host but may be infected if eats raw or insufficiently cooked or fried fish meat. The investigations were conducted in spring 2012 on Danube-Tisa-Danube Canal in the territory of Novi Sad where were collected 52 samples of European catfish (Siluris glanis) weighting 250-450 g. Presence of nematodes in the abdominal cavity, musculature, in the lumen of the stomach and encapsulated in stomach wall was revealed in 6 individuals after examination. The number of parasites per fish ranged from a few up to the 256. Parasites were determined as Eustrongylides sp. - larval form. Samples for pathohistology were taken from the muscles and nodules in stomach wall.
