Abstract

<abstract abstract-type="author" id="ab0005"> <title id="st0005">Abstract</title> <sec> <p id="sp0005">The complete mitochondrial (mt) genome sequence of <italic>Triodontophorus brevicauda</italic>, an intestinal equine nematode parasite was determined for the first time. The circular <italic>T. brevicauda</italic> mt genome is 14, 305 bp in length and contains 36 genes, of which 12 code for protein, 22 for transfer RNA, and two for ribosomal RNA, and lacks <italic>atp</italic>8 mtDNA gene. Phylogenetic analysis based on the concatenated amino acid sequence of the 12 protein-coding genes was performed using three different tree-building methods. The Strongyloidea cluster divides into two large branches, and each nematode family included in our study forms an independent clade, though paraphyly confounds the issue at some nodes. <italic>T. brevicauda</italic> clusters together with <italic>Cylicocyclus insignis</italic> with high statistical support. The mtDNA data in this study not only provide a new mtDNA resource for phylogeny, but also become a novel and useful genetic marker for further studies on the identification, population genetics, and molecular epidemiology of the genus <italic>Triodontophorus</italic> in equine.</p> </sec> </abstract>
