Title: Non-invasive surveys of mammalian viruses using environmental DNA Document date: 2020_3_29
ID: nil1vv6h_15
Snippet: From the 12 sediment samples tested, two from Mongolia and one from Tanzania yielded viral sequences (25%) representing three viral families including: Retroviridae, Adenoviridae and Papillomaviridae. Mongolian sediment sample SM6 was positive for four contigs mapping to the protease (pro) gene of the Jaagsiekte sheep retrovirus (JSRV) with 100% identity (Suppl. Fig. 11A ). JSRV from this sample was further confirmed by PCR (Suppl. Fig. 11A ). M.....
Document: From the 12 sediment samples tested, two from Mongolia and one from Tanzania yielded viral sequences (25%) representing three viral families including: Retroviridae, Adenoviridae and Papillomaviridae. Mongolian sediment sample SM6 was positive for four contigs mapping to the protease (pro) gene of the Jaagsiekte sheep retrovirus (JSRV) with 100% identity (Suppl. Fig. 11A ). JSRV from this sample was further confirmed by PCR (Suppl. Fig. 11A ). Mongolia sediment sample SM20 was positive for Equine adenovirus (100% identity) with a contig mapping to a region comprised between the pVI and hexon capsid genes (Suppl. Fig. 11B ). Given that multiple equine species are found in the Gobi Desert in Mongolia, it is likely that the water sources sampled may have been frequented by these species [10] . The sediment sample from Tanzania ST38 was positive for a Zetapapillomavirus related to the Equus caballus papillomavirus and Equus asinus papillomavirus (74% identity; E1-E2 genes) (Suppl. Fig. 11C ; Suppl. Fig. 12 ), consistent with the detection of Plains zebra's (Equus quagga) DNA from this water source [3] . Given that both captive and wild zebras have been known to contract bovine papillomaviruses [10, 11] it is likely that they are susceptible to different equine papillomaviruses.
