The paper present data on species composition of helminths of shrews in the State Nature reserve «Malaya Sosva», Western Siberia, Russia. We found 22 helminths species in four species of shrews (Sorex araneus, S. caecutiens, S. minutus and Neomys fodiens), including 15 species of cestodes, six nematodes and one trematode. We registered for the first time two helminth species of shrews on the territory of the Nature reserve «Malaya Sosva»: cestode Polycercus and nematode Ganguleterakis sp. 21 Species of parasitic worms have been found in S. araneus, 11 species in S. caecutiens, 9 in S. minutus, and 3 in N. fodiens. We found nematodes Aonchotheca kutori, Longistriata depressa, L. didas, Parastrongyloides winchesi, Soboliphyme jamesoni and cestodes Ditestolepis diaphana, Staphylocystis sibirica, Monocercus arionis in all the shrews of the genus Sorex. The water shrew was infected with nematodes P. winchesi and L. didas. We found only one cestode species in the water shrew – Monocercus sp. The nematode L. didas and cestode D. diaphana were dominant parasites in the common shrew. Rare and very rare helminths constitute a large part of the species diversity of parasites of the common shrew (15 species). Helminth infracommunities of shrews can contain from 1 to 12 species of helminth. The infection of shrews was most often caused by nematodes in the combination with cestodes. The trematode Rubenstrema exasperatum was found only in S. araneus. All the studied species of shrews were infected with helminth for 100%. The maximum intensity was reached in one S. araneus individual, infected with 497 parasites . The smallest number of parasites in one infected individual (3) was found in the water shrew. Data on infestation of shrews can be used to assess the status of their populations, and for environmental monitoring.
