Peduovirus
''Peduovirus'' (also known as P2-like phages and P2-like viruses) is a genus of viruses in the order ''Caudovirales'', in the family ''Myoviridae'', in the subfamily '' Peduovirinae''. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are 15 species in this genus. Taxonomy The following species are recognized: *'' Citrobacter virus R18C'' *'' Escherichia virus 12474III'' *'' Escherichia virus fiAA91ss'' *'' Escherichia virus magyaro'' *''Escherichia virus P2'' *'' Escherichia virus P2-2H1'' *'' Escherichia virus P2-2H4'' *'' Escherichia virus P2-4A7b'' *'' Escherichia virus P2-4B2'' *'' Escherichia virus P2-4C9'' *'' Escherichia virus P2-4E6b'' *'' Escherichia virus pro147'' *'' Escherichia virus pro483'' *'' Escherichia virus Wphi'' *'' Yersinia virus L413C'' Structure Peduoviruses are nonenveloped, with a head and tail. The icosahedral head is approximately 60 nm in diameter and a dextral symmetry (T=7), composed of 72 capsomers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hpunavirus
''Hpunavirus'' (synonyms ''Hp1likevirus'' and ''Hpunalikevirus'') 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. 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 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 a sheath, which loosens and slides around the tail core upon contraction. Genome Both species have been fully sequenced. They range between 30k and 34k nucleotides, with 37 to 45 proteins. All complete genomes are av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myoviridae
''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. 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 ''Schizot4virus'' being 111 nm in length. Within the genera on the basis of protein homology the species have been divided into a number of groups. The subfamily ''Peduovirinae'' have virions with heads of 6 ...

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. 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,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. 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 particles, or ''virions'', consisting of (i) the genetic material, i.e ...
