| Mason-Pfiser virus | A D-type retrovirus in the subfamily Oncornaviridae that was isolated from a mammary carcinoma of a rhesus monkey. (05 Mar 2000) |
|---|---|
| vesicular exanthema of swine virus | The type species of the genus calicivirus, an RNA virus infecting pigs. The resulting infection is an acute febrile disease which is clinically indistinguishable from foot and mouth disease. Transmission is by contaminated food. (12 Dec 1998) |
| vesicular stomatitis-indiana virus | The type species of vesiculovirus causing a disease symptomatically similar to foot-and-mouth disease in cattle, horses, and pigs. It may be transmitted to other species including humans, where it causes influenza-like symptoms. (12 Dec 1998) |
| vesicular stomatitis virus | <virology> Rhabdovirus causing the disease soremouth in cattle. Widely used as a laboratory tool especially in studies on the spike glycoprotein as a model for the synthesis, post translational modification and export of membrane proteins. (18 Nov 1997) |
| parrot virus | An obsolete term for Chlamydia psittaci. Synonym: Pacheco's parrot disease virus. (05 Mar 2000) |
| cat distemper virus | A virus of the genus Parvovirus that causes panleukopenia; the virus infects all Felidae, raccoons and mink, but not dogs or other Canidae. Synonym: cat distemper virus, panleukopenia virus of cats. (05 Mar 2000) |
| Mayaro virus | A virus of the genus Alphavirus, family Togaviridae, causing epidemics of undifferentiated type fever in South America. (05 Mar 2000) |
| cattle plague virus | A species of morbillivirus causing cattle plague, a disease with high mortality. Sheep, goats, pigs, and other animals of the order artiodactyla can also be infected. (12 Dec 1998) |
| Catu virus | An arbovirus of the genus Bunyavirus, of the family Bunyaviridae; an agent of bunyavirus encephalitis. (05 Mar 2000) |
| viral haemorrhagic fever virus | <virology> An epidemic viral illness seen in southern Sudan and Zaire, caused by the Ebola virus. The illness is characterised by fever, malaise, muscle aches, respiratory symptoms, diarrhoea, vomiting, epistaxis, haemoptysis, haematemesis, rash, tremors and subconjunctival haemorrhages. Transmitted by close bodily contact with infected individuals (blood, faeces and body fluids). Incubation is-21 days with initial symptoms of fever and headache. There is no specific treatment and death can occur within 10 days. (27 Sep 1997) |
| CA virus | <abbreviation> Croup-associated virus. (05 Mar 2000) |
| measles virus | <virology> Paramyxovirus that causes the childhood disease measles and is responsible for subacute sclerosing panencephalitis. (18 Nov 1997) |
| measles virus vaccine | Vaccine containing live, attenuated strains of measles virus prepared in chick embryo cell culture. See: measles, mumps, and rubella vaccine. (05 Mar 2000) |
| virus | <virology> Viruses are obligate intracellular parasites of living but noncellular nature, consisting of DNA or RNA and a protein coat. They range in diameter from 20-300nm. Class I viruses (Baltimore classification) have double stranded DNA as their genome. Class II have a single stranded DNA genome. Class III have a double stranded RNA genome. Class IV have a positive single stranded RNA genome, the genome itself acting as mRNA. Class V have a negative single stranded RNA genome used as a template for mRNA synthesis. Class VI have a positive single stranded RNA genome but with a DNA intermediate not only in replication but also in mRNA synthesis. The majority of viruses are recognised by the diseases they cause in plants, animals and prokaryotes. Viruses of prokaryotes are known as bacteriophages. (13 Oct 1997) |
| virus activating protease | <enzyme> Endoprotease from chick embryo; activates para- and orthomyoxovirus fusion glycoproteins by cleaving them at a single arginine site; ca(2+) dependent; similar to blood clotting factor x Registry number: EC 3.4.21.- (26 Jun 1999) |
