Herpesvirus 1, Meleagrid
A species in the genus MAREK'S DISEASE-LIKE VIRUSES, in the family HERPESVIRIDAE, infecting turkeys.
Herpesvirus 8, Human
A species in the genus RHADINOVIRUS, subfamily GAMMAHERPESVIRINAE, isolated from patients with AIDS-related and "classical" Kaposi sarcoma.
Herpesvirus 6, Human
The type species of ROSEOLOVIRUS isolated from patients with AIDS and other LYMPHOPROLIFERATIVE DISORDERS. It infects and replicates in fresh and established lines of hematopoietic cells and cells of neural origin. It also appears to alter NK cell activity. HHV-6; (HBLV) antibodies are elevated in patients with AIDS, Sjogren's syndrome, sarcoidosis, chronic fatigue syndrome, and certain malignancies. HHV-6 is the cause of EXANTHEMA SUBITUM and has been implicated in encephalitis.
Herpesvirus 2, Saimiriine
The type species of RHADINOVIRUS, in the subfamily GAMMAHERPESVIRINAE, isolated from squirrel monkeys. It produces malignant lymphomas (LYMPHOMA, MALIGNANT) in inoculated marmosets or owl monkeys.
Herpesvirus 1, Equid
A species of VARICELLOVIRUS causing abortion and respiratory disease in horses.
Herpesviridae
A family of enveloped, linear, double-stranded DNA viruses infecting a wide variety of animals. Subfamilies, based on biological characteristics, include: ALPHAHERPESVIRINAE; BETAHERPESVIRINAE; and GAMMAHERPESVIRINAE.
Herpesvirus 1, Bovine
A species of VARICELLOVIRUS that causes INFECTIOUS BOVINE RHINOTRACHEITIS and other associated syndromes in CATTLE.
Herpesviridae Infections
Virus diseases caused by the HERPESVIRIDAE.
Herpesvirus 7, Human
A species in the genus ROSEOLOVIRUS, of the family HERPESVIRIDAE. It was isolated from activated, CD4-positive T-lymphocytes taken from the blood of a healthy human.
Herpesvirus 4, Bovine
A species in the genus RHADINOVIRUS, subfamily GAMMAHERPESVIRINAE, infecting cattle.
Sarcoma, Kaposi
A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.
Herpesvirus 1, Canid
A species of VARICELLOVIRUS virus that causes a disease in newborn puppies.
Herpesvirus 2, Gallid
The type species of the genus MARDIVIRUS in the family HERPESVIRIDAE. It is the etiologic agent of MAREK DISEASE, infecting domestic fowl and wild birds.
Herpesvirus 5, Bovine
A species of VARICELLOVIRUS that causes a fatal MENINGOENCEPHALITIS in calves.
Herpesvirus 4, Equid
A species of VARICELLOVIRUS and the chief cause of rhinopneumonitis in horses.
Roseolovirus Infections
Herpesvirus 1, Cercopithecine
Alphaherpesvirinae
A subfamily of HERPESVIRIDAE characterized by a short replication cycle. The genera include: SIMPLEXVIRUS; VARICELLOVIRUS; MAREK'S DISEASE-LIKE VIRUSES; and ILTOVIRUS.
Herpesvirus 1, Suid
A species of VARICELLOVIRUS producing a respiratory infection (PSEUDORABIES) in swine, its natural host. It also produces an usually fatal ENCEPHALOMYELITIS in cattle, sheep, dogs, cats, foxes, and mink.
Gammaherpesvirinae
A subfamily of HERPESVIRIDAE characterized by variable reproductive cycles. The genera include: LYMPHOCRYPTOVIRUS and RHADINOVIRUS.
Herpesvirus 4, Human
The type species of LYMPHOCRYPTOVIRUS, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans. It is thought to be the causative agent of INFECTIOUS MONONUCLEOSIS and is strongly associated with oral hairy leukoplakia (LEUKOPLAKIA, HAIRY;), BURKITT LYMPHOMA; and other malignancies.
Herpesvirus 1, Human
The type species of SIMPLEXVIRUS causing most forms of non-genital herpes simplex in humans. Primary infection occurs mainly in infants and young children and then the virus becomes latent in the dorsal root ganglion. It then is periodically reactivated throughout life causing mostly benign conditions.
Virus Latency
The ability of a pathogenic virus to lie dormant within a cell (latent infection). In eukaryotes, subsequent activation and viral replication is thought to be caused by extracellular stimulation of cellular transcription factors. Latency in bacteriophage is maintained by the expression of virally encoded repressors.
Varicellovirus
A genus of the family HERPESVIRIDAE, subfamily ALPHAHERPESVIRINAE. Its species include those causing CHICKENPOX and HERPES ZOSTER in humans (HERPESVIRUS 3, HUMAN), as well as several animal viruses.
