Eucampyvirinae is a subfamily of viruses in the class Caudoviricetes . [1] Bacteria of the genus Campylobacter serve as natural hosts. [2] There are 9 species in this subfamily, assigned to 2 genera. [3] Prior to 2022, eucampyvirinae was in the class Caudovirales , in the family Myoviridae .
The following genera and species are recognized: [3]
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms.
Myoviridae was a family of bacteriophages in the order Caudovirales. The family Myoviridae and order Caudovirales have now been abolished, with the term myovirus now used to refer to the morphology of viruses in this former family. Bacteria and archaea serve as natural hosts. There were 625 species in this family, assigned to eight subfamilies and 217 genera.
Podoviridae was a family of bacteriophage in the order Caudovirales often associated with T-7 like phages. The family and order Caudoviraleshave now been abolished, with the term podovirus now used to refer to the morphology of viruses in this former family. There were 130 species in this family, assigned to 3 subfamilies and 52 genera. This family was characterized by having very short, noncontractile tails. Many former phages in the former family Podoviriade are now classified in the Autographiviridae
Caudoviricetes is a class of viruses known as the tailed bacteriophages. Under the Baltimore classification scheme, the Caudoviricetes are group I viruses as they have double stranded DNA (dsDNA) genomes, which can be anywhere from 18,000 base pairs to 500,000 base pairs in length. The virus particles have a distinct shape; each virion has an icosahedral head that contains the viral genome, and is attached to a flexible tail by a connector protein. The order encompasses a wide range of viruses, many containing genes of similar nucleotide sequence and function. However, some tailed bacteriophage genomes can vary quite significantly in nucleotide sequence, even among the same genus. Due to their characteristic structure and possession of potentially homologous genes, it is believed these bacteriophages possess a common origin.
Alphaherpesvirinae is a subfamily of viruses in the family Herpesviridae, primarily distinguished by reproducing more quickly than other subfamilies in the Herpesviridae. In animal virology the most important herpesviruses belong to the Alphaherpesvirinae. Pseudorabies virus is the causative agent of Aujeszky's disease in pigs and Bovine herpesvirus 1 is the causative agent of bovine infectious rhinotracheitis and pustular vulvovaginitis. Mammals serve as natural hosts. There are currently 45 species in this subfamily, divided among 5 genera with one species unassigned to a genus. Diseases associated with this subfamily include: HHV-1 and HHV-2: skin vesicles or mucosal ulcers, rarely encephalitis and meningitis, HHV-3: chickenpox (varicella) and shingles, GaHV-2: Marek's disease.
The International Committee on Taxonomy of Viruses (ICTV) authorizes and organizes the taxonomic classification of and the nomenclature for viruses. The ICTV develops a universal taxonomic scheme for viruses, and thus has the means to appropriately describe, name, and classify every virus taxon. 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 identifying new taxa and delimiting the boundaries of species, genera, families, etc. typically is performed by study groups of experts in the families.
Avulavirinae is a subfamily of viruses in the family Paramyxoviridae. Members of the subfamily are collectively known as avulaviruses. All members of the subfamily primarily infect birds. Avulavirinae was previously recognized as the genus Avulavirus before being elevated to a subfamily. The term avula comes from "avian rubula", distinguishing it from rubulaviruses of the subfamily Rubulavirinae due to avulaviruses only infecting birds and translating protein V from an edited RNA transcript. The most notable avulavirus is the Newcastle disease virus, a strain of Avian orthoavulavirus 1.
Autographiviridae is a family of viruses in the order Caudovirales. Bacteria serve as natural hosts. There are 373 species in this family, assigned to 9 subfamilies and 133 genera.
Okubovirus is a genus of viruses in the order Caudovirales, in the family Herelleviridae, in the subfamily Spounavirinae. Bacteria serve as natural hosts. There are two species in this genus.
Vibrio virus K139 is a bacteriophage of the family Myoviridae, genus Longwoodvirus.
Peduovirus is a genus of viruses in the family Peduoviridae of the class Caudoviricetes. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are 30 recognised species in this genus.
Peduoviridae is a family of viruses in the class Caudoviricetes. It was previously treated as a subfamily of the morphology based family Myoviridae, which has been found to be paraphyletic and is no longer recognised. Bacteria serve as natural hosts. There are 126 species in this subfamily, assigned to 58 genera.
Tevenvirinae is a subfamily of viruses in the family Straboviridae of class Caudoviricetes. The subfamily was previously placed in the morphology-based family Myoviridae, which was found to be paraphyletic in genome studies and abolished in the 2021 International Committee on Taxonomy of Viruses (ICTV) classification. Bacteria and archaea serve as natural hosts. There are 148 species in this subfamily, included in 14 genera.
Hapunavirus is a genus of viruses in the class Caudoviricetes, not assigned to a subfamily. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus. Hapunavirus was classified in the family Myoviridae.
Ackermannviridae is a family of viruses in the class Caudoviricetes. Gammaproteobacteria in the phylum Pseudomonadota serve as natural hosts. There are two subfamilies, ten genera, and 63 species in the family.
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.
Fletchervirus is a genus of virus of the subfamily Eucampyvirinae and the phylum Uroviricota (Bacteriophage). This genus contains 5 different species. The family Myoviridae that this genus is a part of is identified from other bacteriophage species by its choice of host, bacteria of the genus Campylobacter. Fletchervirus like most bacteriophage are harmless to humans and thus have no antiviral drugs associated with them. They can be found worldwide and just like most bacteriophage species are found in almost all ecological environments including humans.
Straboviridae is a family of bacteriophages in the class Caudoviricetes. The viruses in this family were formerly place in the morphology-based family Myoviridae, which was found to be paraphyletic in genome studies and abolished in the 2021 International Committee on Taxonomy of Viruses (ICTV) classification, although the term myovirus is still used to refer to the morphology of viruses in this new family. Bacteria and archaea serve as natural hosts. There were 209 species in this family, assigned to 36 genera and three subfamilies.
Kyanoviridae is a family of bacteriophages in the class Caudoviricetes. The viruses in this family were formerly place in the morphology-based family Myoviridae, which was found to be paraphyletic in genome studies and abolished in the 2021 International Committee on Taxonomy of Viruses (ICTV) classification, although the term myovirus is still used to refer to the morphology of viruses in this new family. Bacteria and archaea serve as natural hosts. There are currently 66 species in this family, assigned to 54 genera.
