Reassembly and improved annotation of the nearly complete mitochondrial genome of <i>Echinostoma caproni</i> (Digenea: Echinostomatidae) from an Egyptian isolate

We report a nearly complete mitochondrial genome (mitogenome) of <i>Echinostoma caproni</i> (Egyptian isolate), which was reassembled and thoroughly annotated from whole-genome sequencing data available from Sequence Read Archive (accession No. ERS055227). Although a mitogenome of <i>E. caproni</i> has previously been deposited in GenBank (accession No. AP017706), it represents a partial sequence lacking the transfer RNA (tRNA)-Ser2 and possessing only a short non-coding region. In contrast, the newly reconstructed mitogenome in this study is 14,549 bp in length and comprises 12 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and a 1,256 bp non-coding region containing 4 repeat units. The annotated sequence has been deposited in the Third Party Annotation database in GenBank (accession No. BK071757). Phylogenetic inference based on mitogenomic data indicates that <i>E. caproni</i> is closely related to <i>E. miyagawai</i> strains. This improved mitogenome provides a reliable genomic resource for comparative mitogenomic analyses and phylogenetic studies within the family Echinostomatidae.
