The Human alphaherpesvirus 1 virus can be classified into six clades. [2] Four of these occur in East Africa, one in East Asia and one in Europe and North America. This suggests that the virus may have originated in East Africa. The most recent common ancestor of the Eurasian strains appears to have evolved ~60,000 years ago. [3]
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and ...
Dog pox is an infection of canines which may be caused by the canine herpes virus, and can result in symptoms ranging from no symptoms to inflammation of the respiratory or digestive tract to skin inflammation and lesions. Over 60% of adult male dogs exhibit lesions as a result of this infection. [12]
In this fashion, the virus can persist in the cell (and thus the host) indefinitely. While primary infection is often accompanied by a self-limited period of clinical illness, long-term latency is symptom-free. [citation needed] Chromatin dynamics regulate the transcription competency of entire herpes virus genomes.
Pseudorabies virus is the causative agent of Aujeszky's disease in pigs and Bovine herpesvirus 1 is the causative agent of bovine infectious rhinotracheitis and pustular vulvovaginitis. [1] [2] Mammals serve as natural hosts. There are currently 45 species in this subfamily, divided among 5 genera with one species unassigned to a genus.
There are two types of herpes simplex virus, type 1 (HSV-1) and type 2 (HSV-2). [1] HSV-1 more commonly causes infections around the mouth while HSV-2 more commonly causes genital infections. [2] They are transmitted by direct contact with body fluids or lesions of an infected individual. [1] Transmission may still occur when symptoms are not ...
Gallid alphaherpesvirus 1 (GaHV-1) is a species of virus in the order Herpesvirales, family Herpesviridae, subfamily Alphaherpesvirinae, and genus Iltovirus. [2] Originally recognised in chickens in the United States in 1926, this virus causes avian infectious laryngotracheitis (abbreviated as AILT, ILT, or LT), a potentially fatal, economically deleterious disease, widely recognised as one of ...
The virus Psittacid alphaherpesvirus 1 is the etiologic agent that causes Pacheco's disease. This virus species is closely related to Gallid alphaherpesvirus 1. [2] It was initially identified as a herpesvirus by examining its virion size, sensitivity to ether, the formation of intranuclear inclusions, its ability to thicken the nuclear membranes of the host cells.
