Discovery and comparative genomic analysis of elk circovirus (ElkCV), a novel circovirus species and the first reported from a cervid host.

ABSTRACT: The complete genome sequence of a novel circovirus (elk circovirus (ElkCV) Banff/2019) was determined via high throughput sequencing of liver tissue from a euthanized Rocky Mountain elk (Cervus canadensis nelsoni) from Alberta, Canada. The genome is circular and 1,787 nucleotides long, with two major ORFs encoding predicted proteins. Comparative genomic analysis to 4,164 publicly available complete and near complete circovirus genomes showed that ElkCV shares approximately 65% pairwise genome-wide nucleotide identity with the most closely related circovirus species, porcine circoviruses (PCV) 1 and 2 and bat-associated circovirus (BatACV) 11. ElkCV features a stem-loop within the origin of replication region characteristic of circoviruses. However, it differs from those found in PCV1, PCV2
