Free-range cattle are common in the Northeast China area, which have close contact with farmers and may carry virus threatening to cattle and farmers.
Using viral metagenomics we analyzed the virome in plasma samples collected from 80 cattle from the forested region of Northeast China.
The virome of cattle plasma is composed of the viruses belonging to the families including Parvoviridae, Papillomaviridae, Picobirnaviridae, and divergent viral genomes showing sequence similarity to circular Rep-encoding single stranded (CRESS) DNA viruses. Five such CRESS-DNA genomes were full characterized, with Rep sequences related to circovirus and gemycircularvirus. Three bovine parvoviruses belonging to two different genera were also characterized.
The virome in plasma samples of cattle from the forested region of Northeast China was revealed, which further characterized the diversity of viruses in cattle plasma.
