Characterization of the complete mitochondrial genome of the lung fluke, .

In this study, the complete mitochondrial genome of human lung fluke, , was recovered through Illumina sequencing data. This complete mitochondrial genome of is 13,927 bp in length and has a base composition of A (16.6%), T (41.8%), C (13.%), and G (28.4%), demonstrating an obvious bias of high AT content (58.4%). The mitochondrial genome contains a typically conserved structure, encoding 12 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (12S rRNA and 16S rRNA), and a control region (D-loop region). All PCGs were located on the H-strand. ND4 gene and ND4L gene were overlapped by 39 bp. The nucleotide sequence of 12 PCGs of and other 10 parasite species were used for phylogenetic analysis. The result indicated a relative close relationship with species (AF219379.2).
