Batrachovirus
''Batrachovirus'' is a genus of viruses in the order ''Herpesvirales'', in the family ''Alloherpesviridae ''Alloherpesviridae'' is a family of viruses in the order ''Herpesvirales''. This family includes the species that infect fish and amphibians. Phylogenetic studies have confirmed the validity of this family and suggest that it may be divided in ...''. Frogs serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: raHV-1: Lucké tumor (renal adenocarcinoma). Species The genus consists of the following three species: * '' Ranid herpesvirus 1'' * '' Ranid herpesvirus 2'' * '' Ranid herpesvirus 3'' Structure Viruses in ''Batrachovirus'' are enveloped, with icosahedral and spherical to pleomorphic geometries, and T=16 symmetry. The diameter is around 150-200 nm. Genomes are linear and non-segmented, around 220-231kb in length. Life cycle Viral replication is nuclear, and is lysogenic. Entry into the host cell i ...

Alloherpesviridae
''Alloherpesviridae'' is a family of viruses in the order ''Herpesvirales''. This family includes the species that infect fish and amphibians. Phylogenetic studies have confirmed the validity of this family and suggest that it may be divided into two clades: one consisting of viruses from cyprinid and anguillid hosts and the other of viruses from ictalurid, salmonid, acipenserid, and ranid hosts. There are currently 13 species in this family, divided among four genera. A disease associated with this family includes channel catfish disease. Taxonomy ''Alloherpesviridae'' was established as a family in 2005. Genera The family contains the following four genera: * '' Batrachovirus'' * '' Cyprinivirus'' * '' Ictalurivirus'' * ''Salmonivirus ''Salmonivirus'' is a genus of viruses in the order ''Herpesvirales'', in the family '' Alloherpesviridae''. Salmonidae serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: salHV-3: epiz ...

Herpesvirales
The ''Herpesvirales'' is an order of dsDNA viruses (Baltimore group I) with animal hosts, characterised by a common morphology consisting of an icosahedral capsid enclosed in a glycoprotein-containing lipid envelope. Common infections in humans caused by members of this order include cold sores, genital herpes, chickenpox, shingles, and glandular fever. ''Herpesvirales'' is the sole order in the class ''Herviviricetes'', which is the sole class in the phylum ''Peploviricota''. Virology Morphology All members of the order have a virion structure that consists of a DNA core surrounded by an icosahedral capsid composed of 12 pentavalent and 150 hexavalent capsomeres (T = 16). The capsid has a diameter of ~110 nanometers (nm) and is embedded in a proteinaceous matrix called the tegument, which in its turn is enclosed by a glycoprotein-containing lipid envelope with a diameter of about 200 nm. The DNA genome is linear and double stranded, with sizes in the range 125–290 kb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranid Herpesvirus 1
''Ranid herpesvirus 1'' (RaHV-1), also known as the ''Lucké tumor herpesvirus'' (LTHV), is a double-stranded DNA virus within the order ''Herpesvirales The ''Herpesvirales'' is an order of dsDNA viruses (Baltimore group I) with animal hosts, characterised by a common morphology consisting of an icosahedral capsid enclosed in a glycoprotein-containing lipid envelope. Common infections in humans c ...''. The virus was initially observed within renal tumors in 1934 by Baldwin Lucké, and more recently has become identifiable through the use of PCR in samples isolated from frog tumors. RaHV-1 causes renal tumors within the northern leopard frog, ''Rana pipiens''. The virus has not yet been isolated ''in vitro'' within cell lines, meaning that while its existence and symptoms are fairly evident, its methods of transmission, cell infection, and reproduction are largely unknown. Since it has not been cultured ''in vitro,'' temporal studies regarding the kinetics of virus growth and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
