Survey on wild rodents for endoparasites in Iwate Prefecture, Japan.

Wild rodents (58 Apodemus speciosus, 29 A. argenteus and 7 Microtus montebelli) were surveyed for endoparasites in Iwate Prefecture, Japan, from October to December 1995 and from April to October 1996. Two trematodes (Echinostoma macrorchis, Plagiorchis muris), 4 or more cestodes (Hymenolepis diminuta, Raillietina coreensis, Cladothyridium spp., Cysticercus fasciolaris), 12 nematodes (Carolinensis minutus, Eucoleus sp., Heligmosomoides kurilensis, H. protobullosus, H. speciosus, Heterakis spumosa, Rhabditis (Pelodera) orbitalis, Rictularia cristata, Syphacia emileromani, S. frederici, S. montana, Trichuris sp.) and 3 protozoans (Giardia sp., Trichomonas sp., Trypanosoma sp.) were identified. The two species of Apodemus were similar to each other, but they were extremely different from M. montebelli in parasite fauna.
