Nucleotide sequence variations in a region of the mitochondrial cytochrome c oxidase subunit I (COI) gene (391 bp) were examined within seven species of the genus Taenia and two species of the genus Echinococcus, including ten isolates of T. taeniaeformis and six isolates of E. multilocularis. More than a 12% rate of nucleotide differences between taeniid species was found, allowing the species to be distinguished. In E. multilocularis, no sequence variation was observed among isolates, regardless of the host (gray red-backed vole, tundra vole, pig, Norway rat) or area (Japan, Alaska) from which each metacestode had been isolated. In contrast, six distinct sequences were detected among the ten T. taeniaeformis isolates examined. The level of nucleotide variation in the COI gene within T. taeniaeformis isolates except for one isolate from the gray red-backed vole (TtACR), which has been proposed as a distinct strain or a different species, was about 0.3%-4.1%, whereas the COI gene sequence for TtACR differed from those of the other isolates, with levels being 9.0%-9.5%. Phylogenetic trees were then inferred from these sequence data using two different algorithms.
