Macavirus
''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 (wildebeest for alHV-1 and sheep for ovHV-2), but fatal lymphoproliferative Lymphoproliferative disorders (LPDs) refer to a specific class of diagnoses, comprising a group of several conditions, in which lymphocytes are produced in excessive quantities. These disorders primarily present in patients who have a compromised ... disease when they infect MCF-susceptible hosts, including cattle, deer, bison, water buffalo and pigs. Species The genus consists of the following nine species: * '' Alcelaphine gammaherpesvirus 1'' * '' Alcelaphine gammaherpesvirus 2'' * '' Bovine gammaherpesvirus 6'' * '' Caprine gammaherpesvirus 2'' * '' Hippotragine gammaherpesvirus 1'' * '' Ovine gamm ...

Gammaherpesvirinae
''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. Taxonomy Herpesviruses represent a group of double-stranded DNA viruses distributed widely within the animal kingdom. The family ''Herpesviridae'', which contains eight viruses that infect humans, is the most extensively studied group within this order and comprises three subfamilies, namely ''Alphaherpesvirinae'', ''Betaherpesvirinae'' and ''Gammaherpesvirinae''. Within the ''Gammaherpesvirinae'' there are a number of unclassified viruses including ''Cynomys herpesvirus 1'' (CynGHV-1)Na ...

Herpesviridae
''Herpesviridae'' is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word ''ἕρπειν'' ( 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster (shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established ''Herpesvirus'' as a genus with 23 viruses among four groups. As of 2020, 115 species are recognized, all but one of which are in one of the three subfamilies. Herpesviruses can cause both latent and lytic infections. Nine herpesvirus types are known to primarily infect humans, at least five of which – herpes simplex viruses 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial herpes and genital herpes), varicella zoster virus (or HHV-3; the cau ...

Alcelaphine Gammaherpesvirus 2
''Alcelaphine gammaherpesvirus 2'' (AlHV-2) is a species of ''Macavirus'' that is believed to be responsible for causing hartebeest infections of malignant catarrhal fever. Clinical definition Distantly related to human herpes, a virus of this type is composed of a series of double strand sequences of up to 100 gene segments, aligned along a long chromosome surrounded by terminal DNA segments. The effect of the virus is to cause nasal discharge, a high fever, filmed over eyes, failures of the lymphatic system, inflammation of various mucous membranes, and occasionally necrosis of the upper digestive system. Very advanced cases show signs of decay of the nervous system. Occasionally, lesions, arthritis, and digestive problems such as diarrhea have been observed. Cause The agent of MCF in hartebeests, it is related to other variants that strike down antelopes. It was isolated in 1960 and is believed to be carried as reservoirs by goats, sheep, and other domestic animals. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herpesvirales
The ''Herpesvirales'' is an order of dsDNA viruses (Baltimore group I) 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''. Virology Morphology All members of the order have a virion structure that consists of a DNA core surrounded by an icosahedral capsid composed of 12 pentavalent and 150 hexavalent capsomeres (T = 16). The capsid has a diameter of ~110 nanometers (nm) and is embedded in a proteinaceous matrix called the tegument, which in its turn is enclosed by a glycoprotein-containing lipid envelope with a diameter of about 200 nm. The DNA genome is linear and double stranded, with sizes in the range 125–2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcelaphine Gammaherpesvirus 1
Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease caused by a group of ruminant gamma herpes viruses including ''Alcelaphine gammaherpesvirus 1'' (AlHV-1) and ''Ovine gammaherpesvirus 2'' (OvHV-2) These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and other ungulates such as deer, antelope, and buffalo. In Southern Africa the disease is known as ''snotsiekte'', from the Afrikaans. BMCF is an important disease where reservoir and susceptible animals mix. There is a particular problem with Bali cattle in Indonesia, bison in the US and in pastoralist herds in Eastern and Southern Africa. Disease outbreaks in cattle are usually sporadic although infection of up to 40% of a herd has been reported. The reasons for this are unknown. Some species appear to be particularly susceptible, for example Pére David's deer, Bali cattle and bison, with many deer dying with ...
