Peduovirinae
''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. The family contains 58 genera. Taxonomy The following genera are recognized: * ''Aptresvirus'' * ''Aresaunavirus'' * ''Arsenicumvirus'' * ''Arsyunavirus'' * ''Baylorvirus'' * ''Bielevirus'' * ''Bracchivirus'' * ''Canoevirus'' * ''Catalunyavirus'' * ''Citexvirus'' * ''Dagavirus'' * ''Duodecimduovirus'' * ''Duonihilunusvirus'' * ''Eganvirus'' * ''Elveevirus'' * ''Entnonagintavirus'' * ''Evevirus'' * ''Felsduovirus'' * ''Finvirus'' * ''Firavirus'' * ''Gegavirus'' * ''Gegevirus'' * ''Gemsvirus'' * ''Graikaemvirus'' * ''Hpunavirus'' * ''Inibicvirus'' * ''Irrigatiovirus'' * ''Irtavirus'' * ''Kapieceevirus'' * ''Kayeltresvirus'' * ''Kisquattuordecimvirus'' * ''Kisquinquevirus'' * ''Longwoodvirus'' * ''Maltschvirus'' * ''Mersin ...

Hpunavirus
''Hpunavirus'' (synonyms ''Hp1likevirus'' and ''Hpunalikevirus'') is a genus of viruses in the family '' Peduoviridae''. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus. Taxonomy The following two species are assigned to the genus: :*'' Haemophilus virus HP1'' :*'' Haemophilus virus HP2'' Structure Hpunalikeviruses are nonenveloped, with a head and tail. The head is approximately 60 nm in diameter and an elongated icosahedral In geometry, an icosahedron ( or ) is a polyhedron with 20 faces. The name comes . The plural can be either "icosahedra" () or "icosahedrons". There are infinitely many non- similar shapes of icosahedra, some of them being more symmetrical tha ... symmetry (T=7), composed of 60 hexamers and 12 pentamers (72 capsomers in total). The tail is around 135 nm long, 18 nm wide, has 6 long terminal fibers, 6 short spikes and a small base plate. The tail is enclosed in ...

Myoviridae
''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. Subdivisions The subfamily ''Tevenvirinae'' (synonym: ''Tequatrovirinae'') is named after its type species ''Enterobacteria phage T4''. Members of this subfamily are morphologically indistinguishable and have moderately elongated heads of about 110 nanometers (nm) in length, 114 nm long tails with a collar, base plates with short spikes and six long kinked tail fibers. The genera within this subfamily are divided on the basis of head morphology with the genus ''Tequatrovirus'' (Provisional name: ''T4virus'') having a head length of 137 nm and those in the genus ''Schizotequatrovirus'' being 111 ...

Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 16,000 of the millions of virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or ''virions'', consisting of (i) genetic material, i.e., long molecules of DNA or RNA that ...
