Arch Virol. 2018 Oct;163(10):2913-2915. doi: 10.1007/s00705-018-3913-8. Epub 2018 Jun 21.


The nearly complete genome sequence of a novel polyomavirus from blood samples of Akodon montensis and Calomys tener collected in Brazil was determined by high-throughput sequencing. This virus showed a typical polyomaviruses genome organization, and it was classified as a member of the genus Betapolyomavirus. Our results expand the host range and viral diversity of the family Polyomaviridae.
