This study is a continuation of the research for the inventory of the parasite fauna of small mammals in nature reserves and parks of the North-West European Russia. Data are presented on the species composition and relative abundance of helminths in the common shrew Sorex araneus in the Kivach Strict Nature Reserve (Republic of Karelia, Russia). Findings from the surveys include 21 species of helminths belonging to three systematic groups: trematodes - Brachylaima fulvum, Rubenstrema exasperatum, cestodes Ditestolepis diaphana, Gulyaevolepis tripartita, Neoskrjabinolepis schaldybini, N. singularis, Staphylocystis furcata, Vigisolepis spinulosa, Dilepis undula, Hepatocestus hepaticus, Monocercus arionis, and nematodes - Aonchotheca kutori, Liniscus incrassatus, Eucoleus oesophagicola, Soboliphyme soricis, Parastrongyloides winchesi, Longistriata codrus, L. didas, L. depressa and Porrocaecum depressum, Porrocaecum sp. Representatives of the Palaearctic faunal complex prevail among the helminths parasitic in the common shrew (85 %). Eight species of parasitic worms were recorded in the common shrew from the territory of the Kivach nature reserve for the first time: R. exasperatum, B. fulvum, N. singularis, S. furcata, V. spinulosa, L. incrassatus, E. ophagicola, P. winchesi. These species are typical representatives of the helminth fauna of the common shrew in the middle taiga subzone of Karelia.
