Abstract
Swine stephanuriasis caused by kidney worm Stephanurus dentatus is a parasitic disease in tropical and subtropical countries, leading to economic losses. Despite its significance as a pathogen, the phylogenetic position and taxonomic status of this nematode remain poorly understood. Mitochondrial (mt) genome sequences are known to provide useful genetic markers for investigations in these areas, but mt genome sequences are lacking for S. dentatus. In the present study, we determined the complete mt genome sequences of S. dentatus with an Illumina platform and compared it with the mt genomes of other closely related species. The circular mt genome was 13,735 bp in size with 36 genes. All genes are transcribed in the same direction and the mt gene arrangement is identified as a GA3 pattern, that is the most common pattern of gene arrangement observed in nematodes to date. Phylogenetic analysis using concatenated amino acid sequences of 12 protein-coding genes supported the hypothesis that S. dentatus was closely related to the family Chabertiidae. Our results provided insights into the phylogenetic relationship of the family Syngamidae within the superfamily Strongyloidea.
