Bullavirinae

	Bullavirinae ''Bullavirinae'' is a subfamily of viruses in the family '' Microviridae''. Enterobacteria Enterobacteriaceae is a large family of Gram-negative bacteria. It was first proposed by Rahn in 1936, and now includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but on ... serve as natural hosts. There are 14 species in this subfamily, organized into three genera. Taxonomy The following genera and species are recognized: * Genus: '' Alphatrevirus''; species: '' Escherichia virus alpha3'' '' Escherichia virus ID21'' '' Escherichia virus ID32'' '' Escherichia virus ID62'' '' Escherichia virus NC28'' '' Escherichia virus NC29'' '' Escherichia virus NC35'' '' Escherichia virus phiK'' '' Escherichia virus St1'' '' Escherichia virus WA45'' * Genus: '' Gequatrovirus''; species: '' Escherichia virus G4'' '' Escherichia virus ID52 '' ** '' Escherichia virus Talmos'' * Genus: '' Sinsh ...

	Microviridae ''Microviridae'' is a family of bacteriophages with a single-stranded DNA genome. The name of this family is derived from the ancient Greek word (), meaning "small". This refers to the size of their genomes, which are among the smallest of the DNA viruses. Enterobacteria, intracellular parasitic bacteria, and spiroplasma serve as natural hosts. There are 22 species in this family, divided among seven genera and two subfamilies. Virology The virions are non-enveloped, round with an icosahedral symmetry (T = 1). They have a diameter between 25–27 nanometers and lack tails. Each virion has 60 copies each of the F, G, and J proteins and 12 copies of the H protein. They have 12 pentagonal trumpet-shaped pentamers (~7.1 nm wide × 3.8 nm high), each of which is composed of 5 copies of the G and one of the H protein. Viruses in this family replicate their genomes via a rolling circle mechanism and encode dedicated RCR initiation proteins.Keegstra W, Baas PD, Jansz HS (197 ...

	Escherichia Virus NC29 ''Escherichia'' () is a genus of Gram-negative, non-spore-forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae. In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, ''Escherichia'' species provide a portion of the microbially derived vitamin K for their host. A number of the species of ''Escherichia'' are pathogenic. The genus is named after Theodor Escherich, the discoverer of ''Escherichia coli''. ''Escherichia'' are facultative aerobes, with both aerobic and anaerobic growth, and an optimum temperature of 37 °C. ''Escherichia'' are usually motile by flagella, produce gas from fermentable carbohydrates, and do not decarboxylate lysine or hydrolyze arginine. Species include '' E. albertii'', '' E. fergusonii'', '' E. hermannii'', '' E. marmotae'' and most notably, the model organism and clinically relevant ''E. coli''. ''Shimwellia blattae'' was formerly classified in this genus. Pathogenesis While ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Escherichia Virus G4 Escherichia virus G4 is a bacteriophage that infects ''E. coli''. First isolated in 1973, the phage was originally isolated from samples of raw sewage and has 5,577 nucleotides. Its isometric capsid contains a single-stranded circular genome of about 5.5 kbp. Phage G4 bears high genetic and structural similarity to the phage ΦX174, though the two phage genomes are up to 39 percent different by sequence. Synthetic G4 Synthetic G4 (syn-G4) has the appearance of an icosahedral protein shell and is 50 nm in diameter. has been synthesized through Polymerase Chain Reaction (PCR) assembly of short oligonucleotides. The synthetic phage G4 genomes were effective in ''E. coli ''Escherichia coli'' (),Wells, J. C. (2000) Longman Pronunciation Dictionary.
