As most host-parasite relationships between endemic mammals and their parasitic nematodes are regarded as a part of natural micro-ecosystems, we have investigated the parasite fauna of Shiretoko Peninsula, Japan. In the present paper, we will report the fauna of small mammals collected in the peninsula. The mammalian species examined were eight including Sorex caecutiens, Sciurus vulgaris (abbreviated to Sv), Myodes rutilus, M. rufocanus (Mr), Apodemus speciosus (As), A. argenteus (Aa), Martes zibellina (Mz), and Mustela itatsi. Up to now, twelve nematode species including Brevistriata skrjabini (Host abbrev.: Sv), Heligmosomum yamagutii (Cr), Heligmosomoides desportesi (Aa), Heligmonoides supeciosus (As, Aa), Syphacia montana (Cr), S. emileromani (Aa), S. agraria (As), Rhabditis strongyloides (Cr), Strongyloides robustus (Sv), Heterakis spumosa (As, Aa), Mastophorus muris (Cr) and Molineus patens (Mz) were identified. This is the first report of the parasitic nematodes from the mammalian species in the peninsula, but there is no endemic helmith species on the peninsula, but this is the first record of the genus Brevistriata from S. vulgaris in Japan. And, S. robustus has not recorded in Hokkaido except for Nopporo Forest Park. Hence, we will investigate intestinal nematode fauna of S. vulgaris in the other part of Hokkaido as soon as posible.
