| cucumber mosaic virus satellite | A satellite RNA (not a satellite virus) which has several types. Different cucumoviruses can act as helper viruses for different types. (12 Dec 1998) |
|---|---|
| haemorrhagic fever virus | <virology> Any of many viruses in the families Flaviviridae, Filoviridae and Bunyaviridae that are often spread by rodents and biting insects, these viruses cause diseasescharacterised by fever and bleeding (such as Ebola). (09 Oct 1997) |
| haemorrhagic fever virus, crimean-congo | The type species of nairovirus of the family bunyaviridae isolated from febrile patients in africa. It is primarily transmitted by ticks and causes a severe, often fatal disease in humans. (12 Dec 1998) |
| 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) |
