NADH dehydrogenase subunit 1 and cytochrome c oxidase subunit I sequences compared for members of the genus Taenia (Cestoda).
Nine members of the genus Taenia (Taenia taeniaeformis, Taenia hydatigena, Taenia pisiformis, Taenia ovis, Taenia multiceps, Taenia serialis, Taenia saginata, Taenia solium and the Asian Taenia) were characterised by their mitochondrial NADH dehydrogenase subunit 1 gene sequences and their genetic relationships were compared with those derived from the cytochrome c oxidase subunit 1 sequence data. The extent of inter-taxon sequence difference in NADH dehydrogenase subunit 1 (approximately 5.9-30.8%) was usually greater than in cytochrome c oxidase subunit 1 (approximately 2.5-18%). Although topology of the phenograms derived from NADH dehydrogenase subunit 1 and cytochrome c oxidase subunit 1 sequence data differed, there was concordance in that T. multiceps, T. serialis (of canids), T. saginata and the Asian Taenia (of humans) were genetically most similar, and those four members were genetically more similar to T. ovis and T. solium than they were to T. hydatigena and T. pisiformis (of canids) or T. taeniaeformis (of cats). The NADH dehydrogenase subunit 1 sequence data may prove useful in studies of the systematics and population genetic structure of the Taeniidae.
