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 .
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 ]
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]
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 ...
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 ...
