Helmintifauna wilków (Canis lupus L.)

The author examined the internal parasites of 18 wolves hunted down on the terrain of the Lublin province during the period 1950-1956. To this material were included also tapeworms from 14 wolves from the Białowieża virgin forest (Puszcza Białowieska) (1941-1943). The infection of the wolves from the Lublin province with worms amounted to 100 per cent. In the collected material the author differentiated 5 species of worms: Alaria alata (Goeze, 1782), Krause, 1914, Taenia hydatigena Pallas, 1766, Uncinaria stenocephala (Railliet, 1884), Crenosoma vulpis (Dujardin, 1845) and Trichinella spiralis (Oven, 1835) Railliet, 1895. The wolf proved to be a new host to Crenosoma vulpis (Dujardin, 1845). In the material collected in Białowieża the author found the following taeniae: Taenia hydatigena Pallas, 1766 and Mesocestoides lineatus Goeze, 1872. The highest number of species of parasites in the wolves was demonstrated in the Soviet Union. Their number reaches 15 species. Exclusively for this area were demonstrated out of the trematodes only Alaria alata, of the tapeworms: Diphyllobothrium decipens, Dipylidium pasquala, Taenia krabei and Taenia polyacantha. The followin nematodes were isolated: Toxocara leoninu, Ancylostoma caninum, Spirocerca lupi , Eucoleus aerophilus and Dioctophyme renale. Out of the Acanthocephala was isolated Ancicola skrjabini. On the Alaska terrains were isolated 8 species of worms out of them only the trematode Alaria canis was exlusive for Alaska. In Poland 6 species of worms were found. Up to the present time were demonstrated for Poland exclusively 3 species. They are Euparyphium malis, Crenosoma vulpis and Thominx böhmi.
