Picobirnavirus is a genus of dsRNA virus, which infect certain mammals. It may be implicated in gastroenteritis in animals and humans.
The viruses have only been isolated from mammals to date.
The virons have a diameter of 35-40 nanometers with a triangulation number (T) = 1, 3 or 4.
The genome is a bipartate and double stranded RNA. The length of the two parts of the genome are 1.7 kilobases (kb) and 2.5 kb. The capsid protein gene is encoded by the second open reading frame of the larger genomic segment.
