Trichomonasvirus is a genus of viruses, in the family Totiviridae . The protozoan parasite Trichomonas vaginalis serves as the natural host. There are four species in this genus. [1] [2]
The following four species are assigned to the genus: [2]
Viruses in Trichomonasvirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 36 nm. Genomes are linear and non-segmented, around 4.6-4.9kb in length. The genome has 2 open reading frames. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Trichomonasvirus | Icosahedral | T=2 | Non-enveloped | Linear |
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Protozoan parasite trichomonas vaginalis serve as the natural host. [1]

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.
Closteroviridae is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
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.
Benyvirus is a genus of viruses, in the family Benyviridae. Plants serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.
Leishmaniavirus is a genus of double-stranded RNA virus, in the family Totiviridae. Protozoa serve as natural hosts, and Leishmaniaviruses are present in several species of the human protozoan parasite Leishmania. There are two species in this genus.
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.
Blosnavirus is a genus of viruses, in the family Birnaviridae. Blotched snakehead fish serve as natural hosts. There are two species in this genus.
Entomobirnavirus is a genus of viruses in the family Birnaviridae. Its natural host is the fly Drosophila melanogaster. There are two species in this genus.
Giardiavirus is a genus of viruses, in the family Totiviridae. Protozoa serve as natural hosts. There is only one species in this genus: Giardia lamblia virus.
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.
Mycoreovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Fungi serve as natural hosts. Diseases associated with this genus include: hypovirulence of the fungal host. The name of the group derives from Ancient Greek myco which means fungus. There are three species in this genus.
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.
Permutotetraviridae is a family of viruses. Lepidopteran insects serve as natural hosts. The family contains one genus that has two species. Diseases associated with this family include: infection outcome varies from unapparent to lethal.
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.
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.
