| Powassan virus | <virology> A virus of the genus Flavivirus (family Flaviviridae), transmitted by ixodid ticks and causing Powassan encephalitis in children; also capable of producing meningoencephalomyelitis in rabbits and children. Origin: Powassan, Canada, where first isolated (05 Mar 2000) |
|---|---|
| hantaan virus | The type species of the genus hantavirus infecting the rodent apodemus agrarius and humans who come in contact with it. It causes syndromes of haemorrhagic fever associated with vascular and especially renal pathology. (12 Dec 1998) |
| hard pad virus | The virus causing hard pad disease, probably canine distemper virus, but sometimes not recovered. (05 Mar 2000) |
| Harvey sarcoma virus | <oncogene> One of a family of oncogenes, first identified as transforming genes of Harvey and Kirsten murine sarcoma viruses. (Name from rat sarcoma because Harvey virus, though a mouse virus, obtained its transforming gene during passage in a rat). Transforming protein coded is p21ras, a GTP-binding protein with GTPase activity, that resembles regulatory G-proteins. (18 Nov 1997) |
| cytopathogenic virus | A virus whose multiplication leads to degenerative changes in the host cell. See: cytopathic effect. (05 Mar 2000) |
| cytoplasmic polyhedrosis virus group | <virology> A group of viruses in the family Reoviridae which infects arthropods (like spiders, insects, crustaceans, horseshoe crabs, etc.). (09 Oct 1997) |
| salivary gland virus | A highly species-specific herpesvirus (cytomegalovirus) with particular affinity for the salivary gland tissue. Synonym: salivary gland virus. (05 Mar 2000) |
| salivary virus | A highly species-specific herpesvirus (cytomegalovirus) with particular affinity for the salivary gland tissue. Synonym: salivary gland virus. (05 Mar 2000) |
| helper virus | <virology> A virus that will allow the replication of a co-infecting defective virus by producing the necessary protein. (18 Nov 1997) |
| San Miguel sea lion virus | A calicivirus, family Caliciviridae, first isolated from sea lions on San Miguel island off the California coast, which is indistinguishable from the vesicular exanthema of swine virus both biophysically and clinically in terms of the vesicular disease syndrome that it produces in swine. (05 Mar 2000) |
| progressive pneumonia virus | A retrovirus (subfamily Lentivirinae) that is the cause of maedi; it is very similar to the visna virus Synonym: medi virus, progressive pneumonia virus. (05 Mar 2000) |
| sarcoma virus | <virology> Virus that causes tumours originating from cells of connective tissue such as fibroblasts. See: Rous sarcoma virus, src. (18 Nov 1997) |
| sarcoma virus, feline | A species of mammalian type c retroviruses (retroviruses type c, mammalian) isolated from fibrosarcoma in cats. The virus is actually a recombinant feline leukaemia virus (felv) where part of the genome has been replaced by cellular oncogenes. It is unique to individuals and not transmitted naturally to other cats. Fesv is replication defective and requires felv to reproduce. (12 Dec 1998) |
| satellite virus | <virology> A term used in plant virology for a virus associated functionally, at least for the purpose of its own replication, with another virus. (18 Nov 1997) |
| hepatitis A virus | <virology> An RNA virus (hepatovirus) in the family Picornaviridae, that is the causative agent of viral hepatitis type A. The virus replicates in hepatocytes and is presumed to reach the intestine via the bile duct. Transmission occurs by the faecal-oral route. Synonym: infectious hepatitis virus. (20 Sep 2002) |
