    Abstract

    The gastrointestinal helminth fauna of 25 eider ducks (Somateria mollissima L.) in the Netherlands has been described and number of worms counted or estimated. For the most common species maximum worm numbers are given. Five nematode species were found: Amidostomum acutum (max. intensity 1500). Paractiaria formosensis. Streptocara crassicauda, Tetrameres fissispina and Capillaria nyrocinarum (max. intensity 1700). Trematodes were represcrited by 12 species: Cotylurus cormutus, Catatropis verrucosa, Notocotylus attenuatus, Cryptocotyle concavum (max. intensity > 10.000), Psilotrema simillimum (max. intensity > 10.000), Himasthla militaris, Gymnophallus somateriae, G. rostratus, Lacunovermis. macomae, Maritrema gratiosum, Microphallus longicaecum and M. somateriae. The total number of gymnophallid and microphallid digeneans exceded 100.000 in some birds. Other digeneans, not identified at the species level, belonged to the genera Diplostomum, Paramonomum and Levinseniella. Cyclophyllid cestodes (mainly Hymenolepididae) were present in high numbers (max. intensity > 4000), but mostly in the immature stage. One Ligula intestinalis could be identified. Acanthocephalan infections with high numbers (max. intensity 4000) of Profilicollis botulus were very common.
