Small circular DNA viruses in rodents sampled in the USA
Viral DNA was extracted from liver sample of Myodes gapperi using the High Pure viral nucleic acid kit (Roche Diagnostics, USA) was used to extract viral DNA. The extracted DNA was enriched for circular sequences using rolling circle amplification with TempliPhi 100 kit (GE Healthcare, USA) and this was then used to generate Illumina sequencing libraries using the TruSeq Nano DNA kit.
