Helminth fauna of the wolf (Canis lupus Linnaeus, 1758) in Belorussian Polesie

The results of our own long-term helminthological investigations (1980-2010) of wolves in Belorussian Polesie are presented. 87.2% of wolves were infected by helminths according to helminthological autopsy, and 98.5% by coproscopical data. 26 species of helminths were found: 5 trematode species, 9 cestode species, 11 nematode species and 1 acanthocephalan species. The wolf is a new host for nematode Dirofilaria immitis (Leidy, 1856) in Belarus.
