| malignant catarrhal fever virus | A herpesvirus of wide distribution causing malignant catarrhal fever of cattle; sheep and wildebeests harbor inapparent infections and may transmit the virus to cattle. (05 Mar 2000) |
|---|---|
| panleukopenia virus of cats | 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) |
| VEE virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in Venezuela and several other South American countries, in Panama and Trinidad, and occasionally the United States causing Venezuelan equine encephalomyelitis in horses and humans; it seems to be more viscerotropic than neurotropic; the virus is transmitted by Culex mosquitoes. Synonym: VEE virus. (05 Mar 2000) |
| gastroenteritis virus, murine | A species of the coronavirus genus causing hepatitis in mice. Four strains have been identified as mhv 1, mhv 2, mhv 3, and mhv 4 (also known as jhm, which is neurotropic and causes disseminated encephalomyelitis with demyelination as well as focal liver necrosis). (12 Dec 1998) |
| gastroenteritis virus, porcine transmissible | A species of coronavirus causing a fatal disease to pigs under 3 weeks old. (12 Dec 1998) |
| gastroenteritis virus type A | A RNA virus, about 27 nm in diameter, which has not been cultured in vitro; it is the cause of epidemic nonbacterial gastroenteritis; at least five antigenically distinct serotypes have been recognised, including the Norwalk agent. These viruses are probably classified with the Caliciviruses in the family Caliciviridae. Synonym: gastroenteritis virus type A. (05 Mar 2000) |
| gastroenteritis virus type B | <virology> Genus of the Reoviridae having a double layered capsid and 11 double stranded RNA molecules in the genome. They have a wheel like appearance in the electron microscope and cause acute diarrhoeal disease in their mammalian and avian hosts. Probably the most important cause of severe dehydrating diarrhoea in children under three years of age worldwide. Symptoms include nausea, vomiting, low-grade fever and diarrhoea. Aggressive fluid replacement is generally required. (27 Sep 1997) |
| Maloney leukaemia virus | A retrovirus associated with leukaemia in rodents. (05 Mar 2000) |
| pantropic virus | The ordinary strain of yellow fever virus, as distinguished from the neurotropic strain; has an affinity for different tissues. (05 Mar 2000) |
| papilloma virus, bovine | A species of papilloma virus producing large numbers of warts on calves. Connective tissue proliferation is an important component of the warts. (12 Dec 1998) |
| papilloma virus, cottontail rabbit | The type species of papilloma virus. It is reported to occur naturally in cottontail rabbits in north america. (12 Dec 1998) |
| papilloma virus, human | A family of over 60 viruses responsible forcausing warts. The majority of the viruses produce warts on the hands, fingers, and even the face. most of these viruses are innocuous, causing nothing more than cosmetic concerns. Several types of HPV are confined primarily to the moist skin of the genitals, producing genital warts and elevating the risk for cancer of the cervix. These viruses that cause wartlike growths on the genitals and contrribute to cancer of the cervix are sexually transmitted. (12 Dec 1998) |
| mammary cancer virus of mice | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
| mammary tumour virus | <organism, virology> Retrovirus that induces mammary carcinoma in mice. Isolated from highly inbred strains that had very high incidence of the tumours, after the discovery that the disease was transmitted by nursing mothers in milk. Endogenous provirus present in germ line of all inbred mice. Transcription of the provirus is regulated by a viral promoter that increases transcription in response to glucocorticoid hormones. May transform by proviral insertion activating the cellular int 1 oncogene (18 Nov 1997) |
| mammary tumour virus of mice | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
