Genus
dsRNA Viruses

Genus: Dinovernavirus

Family: Spinareoviridae

Genus: Dinovernavirus

 

Distinguishing features

The dinovernavirus genome consists of nine segments of dsRNA. Aedes pseudoscutellaris reovirus (APRV) is currently the only member of this genus and was isolated from persistently infected Aedes pseudoscutellaris cells (AP61).

dsRNA Viruses

Genus: Coltivirus

Family: Spinareoviridae

Genus: Coltivirus

 

Distinguishing features

The coltivirus genome consists of 12 segments of dsRNA. During replication, virions are found in the cell cytoplasm, associated with granular matrices (viral inclusion bodies: VIB), arrays of filaments or tubules, and fine kinky threads. Immunofluorescent staining reveals nucleolar fluorescence. Viruses are transmitted to vertebrate hosts by tick vectors.

dsRNA Viruses

Genus: Aquareovirus

Family: Spinareoviridae

Genus: Aquareovirus

 

Distinguishing features

Aquareoviruses physically resemble orthoreoviruses but possess 11 dsRNA genome segments. They infect a variety of aquatic animals, including finfish and crustaceans. Aquareoviruses replicate in cell cultures of piscine and mammalian origin, at temperatures from 15 and 28 °C. Large syncytia are produced as a typical cytopathic effect of infection by a majority of aquareoviruses.
