Urbanová, Beáta ; Langrová, Iva (advisor) ; Nechybová, Stanislava (referee)
The aim of this work was published data concerning parasites coypu (Myocastor coypus).
The first part describes the anatomy and the ethology of a coypu. Nutria is a relatively large rodent, native from South America. It lives near the water areas in small family groups which are lead by the old female. Its body is adapted to the life in water. Nutria is herbivores, which eats littoral and aquatic plants. It is a polyestric animal which gives birth to about six nidifugous pups. The nutria is the non-native species in the Czech Republic. The first import of nutrias was held in 1924 from Argentina. After that they escaped from the farms and due to they got into the wild.
The second part of this work characterizes parasites that have been diagnosed in nutrias. Protozoa diseases cause the coccidia and Toxoplasma. The coccidia are parasites of the genus Eimeria and belong to the most dangerous diseases for nutrias. The trematodes (Fasciola hepatica) also occur in nutrias and causing obturation and destruction of the liver. Anoplocephala sp., Hymenolepis octocornata and Rodentolepis avetjanae from tapeworms parasitize in nutria. Additionally nutrias serve as intermediate hosts of Echinococcus granulosus, Multiceps serialis and Taenia tenuicollis. The diseases, caused by parasitic nematodes from class Nematodes, are caused by parasites Trichinella spiralis, Trichuris myocastoris, the worms of genus Strongyloides (Strongyloides myopotami), and the worms from superfamily Trichostrongyloidae (Trichostrongylus retortaeformis, T. myocastoris). Among the most ectoparasitic diseases frequently belong the scabies (Myocoptes myocastori, Chirodiscoides caviae) and Demodex spp.
