Abstract

Over that last decade, coupling multiple strand displacement approaches with high throughput sequencing have resulted in the identification of genomes of diverse groups of small circular DNA viruses. Using a similar approach but with recovery of complete genomes by PCR, we identified a diverse group of single-stranded viruses in yellow-bellied marmot (Marmota flaviventer) fecal samples. From 13 fecal samples we identified viruses in the family Genomoviridae (n = 7) and Anelloviridae (n = 1), and several others that ware part of the larger Cressdnaviricota phylum but not within established families (n = 19). There were also circular DNA molecules identified (n = 4) that appear to encode one viral-like gene and have genomes of <1545 nts. This study gives a snapshot of viruses associated with marmots based on fecal sampling.

Keywords: Anelloviridae; Cressdnaviricota; Genomoviridae; Marmota flaviventer.
