We present the complete mitochondrial genome of Paragonimus ohirai Miyazaki, 1939 and compare its features with those of previously reported mitochondrial genomes of the pathogenic lung-fluke, Paragonimus westermani, and other members of the genus. The circular mitochondrial DNA molecule of the single fully sequenced individual of P. ohirai was 14,818 bp in length, containing 12 protein-coding, two ribosomal RNA and 22 transfer RNA genes. As is common among trematodes, an atp8 gene was absent from the mitogenome of P. ohirai and the 50 end of nad4 overlapped with the 30 end of nad4L by 40 bp. Paragonimusohirai and four forms/strains of P. westermani from South Korea and India, exhibited remarkably different base compositions and hence codon usage in protein-coding genes. In the fully sequenced P. ohirai individual, the non-coding region started with two long identical repeats (292 bp each), separated by tRNAGlu. These were followed by an array of six short tandem repeats (STR), 117 bp each. Numbers of the short tandem repeats varied among P. ohirai individuals. A phylogenetic tree inferred from concatenated mitochondrial protein sequences of 50 strains encompassing 42 species of trematodes belonging to 14 families identified a monophyletic Paragonimidae in the class Trematoda. Characterization of additional mitogenomes in the genus Paragonimus will be useful for biomedical studies and development of molecular tools and mitochondrial markers for diagnostic, identification, hybridization and phylogenetic/epidemiological/evolutionary studies.
