Birnaviridae - Wikipedia
Birnaviridae is a family of double-stranded RNA viruses. [1] Salmonid fish, birds and insects serve as natural hosts. There are currently 11 species in this family, divided among seven genera. [2]
Family: Birnaviridae | ICTV
Birnaviridae includes seven genera, members of three of which (Aquabirnavirus, Avibirnavirus, and Blosnavirus) infect vertebrates, members of the two genera (Entomobirnavirus and Dronavirus) infect insects, while other hosts are rotifers (Ronavirus) and molluscs (Telnavirus).
The Formation and Function of Birnaviridae Virus Factories
May 9, 2023 · The Birnaviridae is a family of viruses that have a single protein capsid and a double stranded RNA (dsRNA) genome divided into two segments . Birnaviruses have been isolated from birds, fish, and insects such as mosquitoes and flies, and the sequences of birnaviruses have also been found in pigs, porcupines, and the feces of bats [ 1 , 2 , 3 ...
Birnaviridae - an overview | ScienceDirect Topics
The Birnaviridae family comprises four genera (Aquabirnavirus, Avibirnavirus, Blosnavirus, and Entomobirnavirus) of nonenveloped viruses whose genome consists of two segments (segments A and B) of double-stranded RNA.

Birnaviridae is a family of viruses with bi-segmented dsRNA genomes totalling about 6 kbp forming icosahedral, non-enveloped virions. The family includes four genera, members of three of which (Aquabirnavirus, Avibirnavirus and Blosnavirus) infect vertebrates (excluding mammals), whereas members of ….
Birnaviridae | ICTV
Virion properties. Morphology. Viruses of the family Birnaviridae are non-enveloped, single-shelled particles with a diameter of about 65 nm (Figure 1). The capsid follows a T=13 laevo icosahedral geometry and is made of a single capsid protein, VP2, clustered in trimers and forming 260 projections of about 4 nm at the surface of the particle.
