Discovery of a novel single-stranded DNA virus from a sea turtle fibropapilloma by using viral metagenomics.

ABSTRACT: Viral metagenomics, consisting of viral particle purification and shotgun sequencing, is a powerful technique for discovering viruses associated with diseases with no definitive etiology, viruses that share limited homology with known viruses, or viruses that are not culturable. Here we used viral metagenomics to examine viruses associated with sea turtle fibropapillomatosis (FP), a debilitating neoplastic disease affecting sea turtles worldwide. By means of purifying and shotgun sequencing the viral community directly from the fibropapilloma of a Florida green sea turtle, a novel single-stranded DNA virus, sea turtle tornovirus 1 (STTV1), was discovered. The single-stranded, circular genome of STTV1 was approximately 1,800 nucleotides in length. STTV1 has only weak amino acid level identi
