摘要

The 28S rDNA from nine species of the genus Syphacia collected in Japan was sequenced, and the phylogenetic relationship was inferred from multiple sequence alignment of 28S rDNA by the MAFFT program. Phylogenetic tree indicates that S. petrusewiczi, which was the only species belonging to the subgenus Seuratoxyuris, has diverged earlier than other rodent pinworms examined and was distantly separated from the others genetically. It was revealed that S. agraria and S. vandenbrueli, whose subgeneric status has not been specified, belonged to the subgenus Syphacia together with other 6 species. Syphacia montana from Clethrionomys, Eothenomys and Microtus was very closely related to S. obvelata from Mus, and that S. frederici from Apodemus and S. vandenbrueli from Micromys were comparatively closely related to the former two species. The phylogenetic relationship among the three species of Syphacia found in Japanese Apodemus was inconsistent with the biogeography of host rodents. The co-evolutionary relationship between pinworm species and their host rodents may not be so strict and host switching has probably occurred frequently during the course of evolution.
