Detection and genome characterization of two novel papillomaviruses and a novel polyomavirus in tree shrew ( Tupaia belangeri chinensis ) in China

Background Papillomaviruses (PVs) and polyomaviruses (PyVs) infect diverse vertebrates including human and cause a broad spectrum of outcomes from asymptomatic infection to severe disease. There has been no PV and only one PyV detected in tree shrews, though the genomic properties of tree shrews are highly similar to those of the primates.
