Complete Mitochondrial Genome of a Tongue Worm .

(Ichthyostraca: Pantastomida) is a parasitic pathogen, only reported in China, which can cause a zoonotic disease, pentastomiasis. A complete mitochondrial (mt) genome was 16,521 bp comprising 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 non-coding region (NCR). A phylogenetic tree drawn with the concatenated amino acid sequences of the 6 conserved PCGs (, and ) showed that and constituted a clade Pentastomida which was a sister group of the Branchiura. The complete mt genome sequence of provides important genetic markers for both phylogenetic and epidemiological studies of pentastomids.
