Myoviridae is a family of bacteriophages in the order Caudovirales. Bacteria and archaea serve as natural hosts. There are 625 species in this family, assigned to eight subfamilies and 217 genera.
Podoviridae is a family of bacteriophage in the order Caudovirales often associated with T-7 like phages. There are 130 species in this family, assigned to 3 subfamilies and 52 genera. This family is characterized by having very short, noncontractile tails. Podoviradae are largely understudied and most new isolates are of the phicbkviruses genus, a group of giant viruses that appear to be Caulobacter specific.
Comovirinae is a subfamily of viruses in the order Picornavirales, in the family Secoviridae; its genera were formerly classified in the family Comoviridae. Plants serve as natural hosts. There are 62 species in this subfamily, assigned to 3 genera.
Fiersviridae is a family of positive-strand RNA viruses which infect prokaryotes. Bacteria serve as the natural host. They are small viruses with linear, positive-sense, single-stranded RNA genomes that encode four proteins. All phages of this family require bacterial pili to attach to and infect cells. The family has 185 genera, most discovered by metagenomics. In 2020, the family was renamed from Leviviridae to its current name.
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.
Corticovirus is a genus of viruses in the family Corticoviridae. Corticoviruses are bacteriophages; that is, their natural hosts are bacteria. The genus contains two species. The name is derived from Latin cortex, corticis. However, prophages closely related to PM2 are abundant in the genomes of aquatic bacteria, suggesting that the ecological importance of corticoviruses might be underestimated. Bacteriophage PM2 was first described in 1968 after isolation from seawater sampled from the coast of Chile.
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.
Betaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 108 species in this family, assigned to 13 genera in two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms.
Secoviridae is a family of viruses in the order Picornavirales. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. The family was created in 2009 with the grouping of families Sequiviridae, now dissolved, and Comoviridae, now subfamily Comovirinae, along with the then unassigned genera Cheravirus, Sadwavirus, and Torradovirus.
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.
Picovirinae is a subfamily of viruses in the order Caudovirales, in the family Salasmaviridae. Bacteria serve as natural hosts. There are two genera and seven species in this subfamily.
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.
Hpunavirus is a genus of viruses in the family Myoviridae, within the subfamily Peduovirinae. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus.
Twortvirus is a genus of viruses in the order Caudovirales, in the family Herelleviridae, in the subfamily Twortvirinae. Bacteria serve as natural hosts. There is only one species in this genus: Staphylococcus virus Twort.
Spounavirinae is a subfamily of viruses in the order Caudovirales, in the family Herelleviridae. Bacteria serve as natural hosts. There are currently five species in this subfamily, divided among 2 genera.
Tevenvirinae is a subfamily of viruses in the order Caudovirales, in the family Myoviridae. Bacteria and archaea serve as natural hosts. There are 135 species in this subfamily, most included in 12 genera.
Zindervirus is a genus of viruses in the family Autographiviridae, within the subfamily Molineuxvirinae. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently three species in this genus, including the type species Salmonella virus SP6.
Salasvirus is a genus of viruses in the order Caudovirales, in the family Salasmaviridae, in the subfamily Picovirinae. Bacteria serve as natural hosts. There are four species in this genus.
Spbetavirus is a genus of viruses in the order Caudovirales, in the family Siphoviridae. Bacteria serve as natural hosts. There is only one species in this genus: Bacillus virus SPbeta.
Bullavirinae is a subfamily of viruses in the family Microviridae. Enterobacteria serve as natural hosts. There are 14 species in this subfamily, organized into three genera.
