Equid alphaherpesvirus 1, also called 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 ...
Equine herpesvirus is a group of viruses of the family Herpesviridae that infect horses. Equine herpesvirus 1 of the subfamily Alphaherpesvirinae and genus Varicellovirus Equine herpesvirus 2 of the subfamily Gammaherpesvirinae and genus Rhadinovirus
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.
Equid gammaherpesvirus 5 (EHV-5), also called Equine herpesvirus 5, is a species of virus in the genus Percavirus, subfamily Gammaherpesvirinae, family Herpesviridae, and order Herpesvirales. It is thought to be the cause of a chronic lung disease of adult horses ; equine multinodular pulmonary fibrosis .
Equid gammaherpesvirus 2, also called 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 , [ 2 ] in the genus ...
Treatment options for antiviral resistant pathogens [ edit ] If a virus is not fully wiped out during a regimen of antivirals, treatment creates a bottleneck in the viral population that selects for resistance, and there is a chance that a resistant strain may repopulate the host. [ 53 ]
EHV-4 rarely causes abortion in infected pregnant mares unlike its EHV-1 counterpart. [5] Although there is no specific treatment for the disease once a horse is infected, vaccination against EHV-1 and EHV-4 is recommended as part of preventative herd health for those at high risk of infection. Multiple vaccines are available (Duvaxyn EHV1,4 ...
In the United States, many people also vaccinate against Equine Herpes Virus strains 1 and 4. Many additional vaccines may be needed, depending on local conditions and risk, including Rhodococcus equi (strangles), Botulism, or Potomac Horse Fever. [10]
