Abstract

Fibropapillomatosis is a neoplastic disease that afflicts sea turtles. Although it is disseminated worldwide, cases of the disease have not been reported in the southeastern Pacific region. We describe a case of fibropapillomatosis in a green sea turtle (Chelonia mydas) during its rehabilitation at the Machalilla National Park Rehabilitation Center, Ecuador. Viral presence was confirmed by PCR, targeting fragments of the chelonid alphaherpesvirus 5 (ChHV5) unique long (UL) genes, UL27, UL28, and UL30. The amplicons were sequenced and included in a global phylogenetic analysis of the virus with other reported sequences from GenBank. Results showed that the available viral sequences segregated into five phylogeographic groups: western Atlantic and eastern Caribbean, central Pacific, western Pacific, Atlantic, and eastern Pacific groups. The concatenated ChHV5 sequences from Ecuador clustered with the eastern Pacific sequences.
