Rhadinovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Gammaherpesvirinae. Humans and other mammals serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: Kaposi's sarcoma, primary effusion lymphoma and multicentric Castleman's disease, caused by Human gammaherpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV). The term rhadino comes from the Latin fragile, referring to the tendency of the viral genome to break apart when it is isolated.

<i>Arteriviridae</i> Family of viruses in the suborder Arnidovirineae

Arteriviridae is a family of enveloped, positive-strand RNA viruses in the order Nidovirales which infect vertebrates. Host organisms include equids, pigs, Possums, nonhuman primates, and rodents. The family includes, for example, equine arteritis virus in horses which causes mild-to-severe respiratory disease and reproductive failure, porcine reproductive and respiratory syndrome virus type 1 and type 2 in pigs which causes a similar disease, simian hemorrhagic fever virus which causes a highly lethal fever, lactate dehydrogenase–elevating virus which affects mice, and wobbly possum disease virus.

Equid alphaherpesvirus 3, formerly Equine herpesvirus 3 (EHV-3), is a virus of the family Herpesviridae that affects horses.

Equid alphaherpesvirus 4, formerly Equine herpesvirus 4 (EHV-4) is a virus of the family Herpesviridae that cause rhinopneumonitis in horses. It is the most important viral cause of respiratory infection in foals. Like other herpes viruses, EHV-4 causes a lifelong latent infection in affected animals. These horses are usually the source for new infection for foals over two months old, weanlings, and yearlings. Symptoms include fever, loss of appetite, and discharge from the nose. Most infected animals recover in one to three weeks, but death can occur in environments with overcrowding and other stress factors. There are several vaccines available.

Equid alphaherpesvirus 1, formerly Equine herpesvirus 1 (EHV-1), is a virus of the family Herpesviridae that causes abortion, respiratory disease and occasionally neonatal mortality in horses. Initial spread of EHV-1 by a newly introduced horse through direct and indirect contact can lead to abortion and perinatal infection in up to 70 percent of a previously unexposed herd. Abortion usually occurs in the last four months of gestation, two to four weeks after infection of the mare. Perinatal infection can lead to pneumonia and death. Encephalitis can occur in affected animals, leading to ataxia, paralysis, and death. There is a vaccine available, however its efficacy is questionable. The virus varies in severity from sub-clinical to very severe. Most horses have been infected with EHV-1, but the virus can become latent and persist without ever causing signs of infection. In 2006, an outbreak of EHV-1 among stables in Florida resulted in the institution of quarantine measures. The outbreak was determined to have originated in horses imported from Europe via New York, before being shipped to Florida.

Equid gammaherpesvirus 2, formerly Equine herpesvirus 2 (EHV-2), is a virus of the family Herpesviridae, originally known as equine cytomegalovirus due to its slow replication in tissue culture. However, complete sequencing of the EHV-2 genome has demonstrated that it is a member of the subfamily Gammaherpesvirinae, in the genus Percavirus. It has an uncertain role in respiratory disease in horses, but EHV-2 has been isolated from cases exhibiting symptoms such as coughing, conjunctivitis, and swollen submaxillary and parotid lymph nodes.

<i>Gammaherpesvirinae</i> Subfamily of viruses

Gammaherpesvirinae is a subfamily of viruses in the order Herpesvirales and in the family Herpesviridae. Viruses in Gammaherpesvirinae are distinguished by reproducing at a more variable rate than other subfamilies of Herpesviridae. Mammals serve as natural hosts. There are 43 species in this subfamily, divided among 7 genera with three species unassigned to a genus. Diseases associated with this subfamily include: HHV-4: infectious mononucleosis. HHV-8: Kaposi's sarcoma.

<i>Lymphocryptovirus</i> Genus of viruses

Lymphocryptovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Gammaherpesvirinae. This genus includes the human-infecting Human gammaherpesvirus 4, as well as viruses that infect both Old World monkeys and New World monkeys. Other names for the Lymphocryptovirus genus include Lymphocryptoviridae and gamma-1 herpesviruses. There are nine species in this genus. Diseases associated with this genus include: mononucleosis, Burkitt's lymphoma, and nasopharyngeal carcinoma.

<i>Herpesvirales</i> Order of viruses

The Herpesvirales is an order of dsDNA viruses 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.

<i>Equine encephalosis virus</i> Species of virus

Equine encephalosis virus (EEV) is a species of virus the Orbivirus genus, and a member of the Reoviridae family, related to African horse sickness virus (AHSV) and Bluetongue virus (BTV).

Equine multinodular pulmonary fibrosis is a chronic lung disease of horses. There is evidence that the disease is caused by infection with a gammaherpesvirus, equine herpesvirus 5. The disease affects usually adult horses reducing the ability to exercise as a result of the formation of nodular lesions in the lungs.

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 nine species in this genus. Diseases associated with this genus include: inapparent infection in their reservoir hosts, but fatal lymphoproliferative disease when they infect MCF-susceptible hosts, including cattle, deer, bison, water buffalo and pigs.

Percavirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Gammaherpesvirinae. Mammals serve as natural hosts. There are six species in this genus. Diseases associated with this genus include: conjunctivitis, immunosuppression in foals, pneumonia, respiratory disease.
