Salmonivirus
''Salmovirus'', previously called ''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: epizootic epitheliotropic disease. Species The genus consists of the following three species: * '' Salmovirus salmonidallo1'', also called '' Salmonid herpesvirus 1'' * '' Salmovirus salmonidallo2'', also called ''Salmonid herpesvirus 2 Salmonid herpesvirus 2 (SalHV-2) is a species of virus in the genus '' Salmovirus'', family ''Alloherpesviridae'', and order ''Herpesvirales''.

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. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. 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, more than 16,000 of the millions of virus species have been described in detail. 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 viral particles, or ''virions'', consisting of (i) genetic material, i.e., long molecules of DNA or RNA that ...

Herpesvirales
''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 kbp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloherpesviridae
''Alloherpesviridae'' is a family of viruses in the order ''Herpesvirales ''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 cause ...''. 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. The family has four genera. A disease associated with this family is channel catfish disease. Taxonomy ''Alloherpesviridae'' was established as a family in 2005. Genera The family contains the following four genera: * '' Batravirus'' * '' Cyvirus'' * '' Ictavirus'' * '' Salmovirus'' Structure Viruses in ''Alloherpesviridae'' are enve ...

Salmonid Herpesvirus 2
Salmonid herpesvirus 2 (SalHV-2) is a species of virus in the genus '' Salmovirus'', family ''Alloherpesviridae'', and order ''Herpesvirales''. The virus has been referred to as ''Oncorhynchus masou'' virus (OMV) after the disease caused by the virus was first referred to as ''Oncorhynchus masou'' virus disease (OMVD) in 1981. Background The virus was first isolated in the ovarian fluid of masu salmon (''Oncorhynchus masou'') in 1971 from a hatchery in Hokkaido, Japan. In later studies, the virus has been found to be pathogenic and oncogenic to fish other than masu salmon, including coho salmon (''O. kisutch''), kokanee salmon (''O. nerka''), chum salmon (''O. keta''), and rainbow trout (''O. mykiss''), though the virus is still referred to by the species it was initially found to have infected. Salmonid herpesvirus 2 primarily affects such salmonid fish, both wild and farmed, in Japan, though it has been observed in Kuwait. Significant economic loss was suffered by the r ...

Salmonid Herpesvirus 3
Salmonid herpesvirus 3 (SalHV-3) is a species of virus in the genus '' Salmovirus'', family '' Alloherpesviridae'', and order '' Herpesvirales''. The virus has been referred to as epizootic epitheliotrophic disease virus (EEDV) after the disease caused by the virus was first referred to as epizootic epitheliotrophic disease (EED) in 1989. Salmonid herpesvirus 3 affects lake trout (''Salvelinus namaycush''), resulting in several mass mortality events over the years. Background The virus was initially identified in 1988 when investigating the cause behind the mass mortalities of cultured juvenile lake trout within two hatcheries located in the Great Lakes region of the United States. By the end of the 1980s, 15 million lake trout had died due to the virus in the Laurentian Great Lakes Basin. Hatcheries removed the infected fish and heavily sanitized the contaminated areas in order to prevent further spread of the virus. However, a northern Michigan hatchery experienced t ...
