Preplasmiviricota

	Preplasmiviricota ''Preplasmiviricota'' is a phylum of viruses. Taxonomy The phylum contains the following classes: * ''Maveriviricetes Virophages are small, double-stranded DNA viral phages that require the co-infection of another virus. The co-infecting viruses are typically giant viruses. Virophages rely on the viral replication factory of the co-infecting giant virus for th ...'' * '' Polintoviricetes'' * '' Tectiliviricetes'' References Viruses {{Virus-stub ...

picture info	Virus 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. ...

picture info	Maveriviricetes Virophages are small, double-stranded DNA viral phages that require the co-infection of another virus. The co-infecting viruses are typically giant viruses. Virophages rely on the viral replication factory of the co-infecting giant virus for their own replication. One of the characteristics of virophages is that they have a parasitic relationship with the co-infecting virus. Their dependence upon the giant virus for replication often results in the deactivation of the giant viruses. The virophage may improve the recovery and survival of the host organism. Unlike satellite viruses, virophages have a parasitic effect on their co-infecting virus. Virophages have been observed to render a giant virus inactive and thereby improve the condition of the host organism. All known virophages are grouped into the family ''Lavidaviridae'' (from "large virus dependent or associated" + -viridae). Discovery The first virophage was discovered in a cooling tower in Paris, France in 2008. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Tectiliviricetes ''Tectiliviricetes'' (from tectivirid-like) is a class of viruses. Taxonomy The class contains the following orders: * ''Belfryvirales ''Turriviridae'' is a family of viruses; it contains only one genus, ''Alphaturrivirus''. The archaea ''Sulfolobus solfataricus'' serve as natural hosts. There are two species in the genus ''Alphaturrivirus''.
