Salmonivirus

Salmonivirus is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Salmonidae serve as natural hosts. There are currently three species in this genus, including the type species Salmonid herpesvirus 1. Diseases associated with this genus include: salHV-3: epizootic epitheliotropic disease.[1][2]

Structure

Viruses in Salmonivirus 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.[1]

Salmonivirus Spherical Pleomorphic T=16 Enveloped Linear Monopartite

Life cycle

Viral replication is nuclear, and is lysogenic. Entry into the host cell is achieved by attachment of the viral glycoproteins to host receptors, which mediates endocytosis. DNA-templated transcription is the method of transcription. Salmonidae serve as the natural host. Transmission routes are passive diffusion.[1]

Alloherpesviridae

Alloherpesviridae is a family of viruses within 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 12 species in this family, divided among 4 genera. Diseases associated with this family include: channel catfish disease.

Batrachovirus

Batrachovirus is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Frogs serve as natural hosts. There are currently only two species in this genus, including the type species Ranid herpesvirus 1. Diseases associated with this genus include: raHV-1: Lucké tumor (renal adenocarcinoma).

Cyprinivirus

Cyprinivirus is a genus of viruses in the order Herpesvirales, in the family Alloherpesviridae. Freshwater eel serve as natural hosts. There are currently four species in this genus, including the type species Cyprinid herpesvirus 3. Diseases associated with this genus include: hemorrhagic disease.

Equid gammaherpesvirus 5

Equid gammaherpesvirus 5, formerly Equine herpesvirus 5, is thought to be the cause of a chronic lung disease of adult horses, equine multinodular pulmonary fibrosis.

Equine herpesvirus 9

Equine herpesvirus 9 (EHV-9) is a virus of the family Herpesviridae that isolated from a case of epizootic encephalitis in a herd of Thomson's gazelle (Gazella thomsoni) in 1993. Fatal encephalitis was reported from Thomson's gazelle, giraffe, and polar bear in natural infections. The virus was reported in an aborted Persian onager and a polar bear.

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.

Iltovirus

Iltovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Alphaherpesvirinae. Birds, galliform birds, psittacine birds, chickens, turkeys, and quail serve as natural hosts. There are currently only two species in this genus including the type species Gallid herpesvirus 1. Diseases associated with this genus include: acute respiratory diseases: gaHV-1: infectious laryngotracheitis; psHV-1: Pacheco's disease.

Macavirus

Macavirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Gammaherpesvirinae. Mammals serve as natural hosts. There are currently nine species in this genus including the type species Alcelaphine herpesvirus 1. Diseases associated with this genus include: inapparent infection in their reservoir hosts (wildebeest for alHV-1 and sheep for ovHV-2), but fatal lymphoproliferative disease when they infect MCF-susceptible hosts, including cattle, deer, bison, water buffalo and pigs.

Macropodid alphaherpesvirus 1

Macropodid alphaherpesvirus 1 (MaHV-1) is a species of virus in the genus Simplexvirus, subfamily Alphaherpesvirinae, family Herpesviridae, and order Herpesvirales. Macropods serve as natural hosts.

Macropodid alphaherpesvirus 2

Macropodid alphaherpesvirus 2 (MaHV-2) is a species of virus in the genus Simplexvirus, subfamily Alphaherpesvirinae, family Herpesviridae, and order Herpesvirales. Macropods serve as natural hosts.

Malacoherpesviridae

Malacoherpesviridae is a family of DNA viruses in the order Herpesvirales. Molluscs serve as natural hosts, making members of this family the only known herpesviruses to infect invertebrates. There are currently only two species recognised in this family, both classified into separate genera. Disease associated with this family includes sporadic episodes of high mortality among larvae and juveniles. The family name Malacoherpesviridae is derived from Greek word 'μαλακός (malacos) meaning 'soft' and from Greek word 'μαλάκιον (malakion) meaning 'mollusc'.

Murid gammaherpesvirus 4

Murid gammaherpesvirus 4 (MuHV 4) is a virus in the genus Rhadinovirus. It is a member of the subfamily Gammaherpesvirinae in the family Herpesviridae. MuHV 4 infects mice via the nasal passages and causes an acute infectious mononucleosis-like syndrome with elevated levels of leukocytes, and shifts in the relative proportion of lymphocytes along with the appearance of atypical mononuclear cells. Murid herpesvirus 4 currently serves as a model for study of human gamma-herpesvirus pathogenesis.

Muromegalovirus

Muromegalovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Betaherpesvirinae. Rodents serve as natural hosts. There are currently three species in this genus including the type species Murid herpesvirus 1. Diseases associated with this genus include: infected peritoneal macrophages, dendritic cells (DC) and hepatocytes, inducing significant pathology in both the spleen and the liver. Murid viruses murid herpesvirus 1 (MuHV-1) and murid herpesvirus 2 (MuHV-2)—previously defined as mouse cytomegalovirus (MCMV) and rat cytomegalovirus (RCMV)—belong to this genus.

Ostreavirus

Ostreavirus is a genus of viruses in the order Herpesvirales, and one of only two genera in the family Malacoherpesviridae. Molluscs serve as natural hosts.
