Detection of tioman virus in pteropus vampyrus near flores, indonesia

Abstract

Diverse paramyxoviruses have coevolved with their bat hosts, including fruit bats such as flying foxes (Chiroptera: Pteropodidae). Several of these viruses are zoonotic, but the diversity and distribution of Paramyxoviridae are poorly understood. We screened pooled feces samples from three Pteropus vampyrus colonies and assayed tissues, rectal swabs, and oral swabs from 95 individuals of 23 pteropodid species sampled at 17 sites across the Indonesian archipelago with a conventional paramyxovirus PCR; all tested negative. Samples from 43 individuals were screened with next generation sequencing (NGS), and a single Pteropus vampyrus collected near Flores had Tioman virus sequencing reads. Tioman virus is a bat-borne virus in the genus Pararubulavirus with prior evidence of spillover to humans. This work expands the known range of Tioman virus, and it is likely that this isolated colony likely has sustained intergenerational transmission over a long period. © 2021 by the authors.
