Totiviridae is a family of double-stranded RNA viruses. Giardia lamblia, leishmania, trichomonas vaginalis, and fungi serve as natural hosts. The name of the group derives from Latin toti which means undivided or whole. There are 28 species in this family, assigned to 5 genera.
Barnaviridae is a family of non-enveloped, positive-strand RNA viruses. Cultivated mushrooms serve as natural hosts. The family has one genus, Barnavirus, which contains one species: Mushroom bacilliform virus. Diseases associated with this family includes La France disease.
Totivirus is a genus of double-stranded RNA viruses in the family Totiviridae. Fungi serve as natural hosts. The name of the group derives from Latin toti which means undivided or whole. There are seven species in this genus.
Alphachrysovirus is a genus of double-stranded RNA viruses. It is one of two genera in the family Chrysoviridae. They infect fungi, in particular Penicillium. Their name is derived from the Greek word chrysos which means yellow-green. There are 20 species in this genus.
Partitiviridae is a family of double-stranded RNA viruses. Plants, fungi, and protozoa serve as natural hosts. It has been suggested that they can also infect bacteria. The name comes from the Latin partitius, which means divided, and refers to the segmented genome of partitiviruses. There are five genera and 60 species in the family, 15 of which are unassigned to a genus.
Phytoreovirus is a genus of viruses, in the family Reoviridae, in the subfamily Sedoreovirinae. They are non-turreted reoviruses that are major agricultural pathogens, particularly in Asia. Oryza sativa for RDV and RGDV, dicotyledonous for WTV, and leafhoppers serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: WTV: galls (tumor). RDV: dwarf disease of rice. RGDV: dwarfing, stunting, and galls.
Alphaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 65 species in this family, assigned to six genera. Diseases associated with this family include: mosaic and ringspot symptoms.
Aquabirnavirus is a genus of viruses, in the family Birnaviridae. Salmonid fish serve as natural hosts. There are three species in this genus. A disease associated with this genus, Infectious pancreatic necrosis (IPN) in salmonid fish, causes significant losses to the aquaculture industry. Chronic infection in adults, and acute viral disease in young salmonid fish can occur.
Aquareovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Fish, shellfish, and crustacean species serve as natural hosts. Aquareoviruses in general have low or no pathogenicity for fish. However, some cause hemorrhagic disease, hepatitis and pancreatitis. Grass carp hemorrhage virus is the most pathogenic aquareovirus. There are seven species in this genus.
Botrexvirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. Fungi serve as natural hosts. There is only one species in this genus: Botrytis virus X.
Idnoreovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Hymenoptera insects serve as natural hosts. The genus name is an acronym for insect derived non occluded reovirus. There are five species in this genus.
Emesvirus is a genus of positive-strand RNA viruses, in the family Fiersviridae. Enterobacteria serve as natural hosts. There are three species in this genus. In 2020, the genus was renamed from Levivirus to its current name.
Mitovirus is a genus of positive-strand RNA viruses, in the family Mitoviridae. Fungi serve as natural hosts. There are five species in the genus.
Narnavirus is a genus of positive-strand RNA viruses in the family Narnaviridae. Fungi serve as natural hosts. There are two species in this genus. Member viruses have been shown to be required for sexual reproduction of Rhizopus microsporus. Narnaviruses have a naked RNA genome without a virion and derive their name from this feature.
Victorivirus is a genus of viruses, in the family Totiviridae. Filamentous fungi serve as natural hosts. There are 14 species in this genus.
Megabirnaviridae is a family of double-stranded RNA viruses with one genus Megabirnavirus which infects fungi. The group name derives from member's bipartite dsRNA genome and mega that is greater genome size than families Birnaviridae and Picobirnaviridae. There is only one species in this family: Rosellinia necatrix megabirnavirus 1. Diseases associated with this family include: reduced host virulence.
Quadriviridae is a family of double-stranded RNA viruses with a single genus Quadrivirus. The fungi Rosellinia necatrix serves as a natural host. The name of the group derives from the quadripartite genome of its members where in Latin quad means four. There is only one species in this family: Rosellinia necatrix quadrivirus 1.
Betanecrovirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are three species in this genus.
Cardoreovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Sedoreovirinae. Crabs serve as natural hosts. There is only one species in this genus: Eriocheir sinensis reovirus. Diseases associated with this genus include: trembling disease. The name derives from Latin words "carcinus" which means crab and "doeca" which means twelve in reference to the number genome segments.
Dinovernavirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Member viruses replicate in a variety of mosquito cell lines. The name is an abbreviation for double-stranded, insect, novem, rna virus. There is one species in the genus: Aedes pseudoscutellaris reovirus.
