Muscavirus
''Muscavirus'' is a genus of viruses, in the family ''Hytrosaviridae ''Hytrosaviridae'' is a family of double-stranded DNA viruses that infect insects.Abd-Alla A, Vlak J, Bergoin M, Maruniak J, Parker A, Burand J, Jehle J, Boucias D and Hytrosavirus Study Group of the ICTV (2009) ''Hytrosaviridae'': a proposal fo ...''. The fly ''Musca domestica'' is the natural host. There is only one species in this genus: ''Musca hytrosavirus''. Diseases associated with this genus include: salivary gland hypertrophy, and complete sterility of infected female flies by inhibiting eggs development. Structure Viruses in the genus ''Muscavirus'' are enveloped, with rod-shaped geometries. The diameter is around 50 nm. Genomes are circular, around 124kb in length. The genome has 108 open reading frames. Life cycle Viral replication is nuclear. DNA-templated transcription is the method of transcription. ''Musca domestica'' serve as the natural host. Transmission routes are parental and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hytrosaviridae
''Hytrosaviridae'' is a family of double-stranded DNA viruses that infect insects.Abd-Alla A, Vlak J, Bergoin M, Maruniak J, Parker A, Burand J, Jehle J, Boucias D and Hytrosavirus Study Group of the ICTV (2009) ''Hytrosaviridae'': a proposal for classification and nomenclature of a new insect virus family. Arch Virol 154:909–918 The name is derived from ''Hytrosa'', sigla from the Greek ''Hypertrophia'' for 'hypertrophy' and 'sialoadenitis' for 'salivary gland inflammation.' Description The viruses in this family are non occluded, enveloped, rod-shaped virions measuring 500–1,000 nanometers (nm) in length and 50–80 nm in diameter. The virions contain a thin, dense central nucleocapsid that encases the DNA-protein core. The nucleocapsid core is surrounded by an amorphous proteinaceous tegument layer. The outer surface of the virions is studded with helical polymeric structure composed of virally-encoded and host-derived protein dimers. The virions contain at least 35 ...

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 ...
