Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms.
The Caliciviridae are a family of "small round structured" viruses, members of Class IV of the Baltimore scheme. Caliciviridae bear resemblance to enlarged picornavirus and was formerly a separate genus within the picornaviridae. They are positive-sense, single-stranded RNA which is not segmented. Thirteen species are placed in this family, divided among eleven genera. Diseases associated with this family include feline calicivirus, rabbit hemorrhagic disease virus, and Norwalk group of viruses (gastroenteritis). Caliciviruses naturally infect vertebrates, and have been found in a number of organisms such as humans, cattle, pigs, cats, chickens, reptiles, dolphins and amphibians. The caliciviruses have a simple construction and are not enveloped. The capsid appears hexagonal/spherical and has icosahedral symmetry with a diameter of 35–39 nm.
The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclatures for viruses. The ICTV has developed a universal taxonomic scheme for viruses, and thus has the means to appropriately describe, name, and classify every virus that affects living organisms. The members of the International Committee on Taxonomy of Viruses are considered expert virologists. The ICTV was formed from and is governed by the Virology Division of the International Union of Microbiological Societies. Detailed work, such as delimiting the boundaries of species within a family, typically is performed by study groups of experts in the families.
Marnaviridae is a family of positive-stranded RNA viruses in the order Picornavirales. The first species of this family that was isolated is Heterosigma akashiwo RNA virus (HaRNAV) in the genus Marnavirus, that infects the toxic bloom-forming Raphidophyte alga, Heterosigma akashiwo. Using a sequence-based framework an additional twenty marine RNA viruses have been added to the family.
Benyvirus is a genus of viruses, in the family Benyviridae. Plant serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: BNYVV: rhizomania.
Hypovirus is a genus of viruses, in the family Hypoviridae. Fungi serve as natural hosts. There are four species in this genus. Infection reduces the virulence of its parasitic host, making it a hyperparasite useful for blight control.
Aspiviridae, formerly Ophioviridae, is a family of segmented negative-strand RNA viruses which infect plants. Member viruses are characterized by an elongated and highly filamentous and flexible nucleocapsid with helical symmetry. It is a monotypic taxon containing only one genus, Ophiovirus. Aspiviridae is also the only family in the order Serpentovirales, which in turn is the only order in the class Milneviricetes.
Brazilian hemorrhagic fever (BzHF) is an infectious disease caused by Brazilian mammarenavirus, an arenavirus. Brazilian mammarenavirus is one of the arenaviruses from South America to cause hemorrhagic fever. It shares a common progenitor with Argentinian mammarenavirus, Machupo mammarenavirus, Tacaribe mammarenavirus, and Guanarito mammarenavirus. It is an enveloped RNA virus and is highly infectious and lethal. Very little is known about this disease, but it is thought to be transmitted by the excreta of rodents. This virus has also been implicated as a means for bioterrorism, as it can be spread through aerosols.
Betacoronavirus 1 is a species of coronavirus which infects humans and cattle. The infecting virus is an enveloped, positive-sense, single-stranded RNA virus and is a member of the genus Betacoronavirus and subgenus Embecovirus. Like other embecoviruses, it has an additional shorter spike-like surface protein called hemagglutinin esterase (HE) as well as the larger coronavirus spike protein.
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.
Equid alphaherpesvirus 8 is a species of virus in the genus Varicellovirus, subfamily Alphaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Macacine betaherpesvirus 8 (McHV-8) is a species of virus in the genus Cytomegalovirus, subfamily Betaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Murid betaherpesvirus 8 (MuHV-8) is a species of virus in the genus Muromegalovirus, subfamily Betaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Gorilline gammaherpesvirus 1 (GoHV-1), commonly known as herpesvirus gorilla is a species of virus in the genus Lymphocryptovirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Papiine gammaherpesvirus 1 (PaHV-1), commonly known as baboon lymphocryptovirus, is a species of virus in the genus Lymphocryptovirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Suid gammaherpesvirus 5 (SuHV-5) is a species of virus in the genus Macavirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales.
Redondoviruses are a family of human-associated DNA viruses. Their name derives from the inferred circular structure of the viral genome . Redondoviruses have been identified in DNA sequence based surveys of samples from humans, primarily samples from the oral cavity and upper airway.
Thaspiviridae is a family of spindle-shaped viruses that is not assigned to any higher taxonomic ranks. The family contains a single genus, Nitmarvirus, which contains a single species, Nitmarvirus NSV1.
Herelleviridae is a family of bacterial viruses of the order Caudovirales infecting members of the phylum Firmicutes. The family has five subfamilies, 33 genera and 92 species.
Ribozyviria is a realm of satellite nucleic acids. Established in ICTV TaxoProp 2020.012D, the realm is named after the presence of genomic and antigenomic ribozymes of the Deltavirus type. Additional common features include a rod-like structure, a RNA-binding "delta antigen" encoded in the genome, and animal hosts. Furthermore, the size range of the genomes of these viruses is between around 1547–1735nt, they encode a hammerhead ribozyme or a hepatitis delta virus ribozyme, and their coding capacity only involves one conserved protein. Most lineages of this realm are poorly understood, the notable exception being members of the genus Deltavirus, the causal agents of Hepatitis D in humans.
