| encephalitis viruses | A collection of single-stranded RNA viruses scattered across the bunyaviridae, flaviviridae, and togaviridae families whose common property is the ability to induce encephalitic conditions in infected hosts. (12 Dec 1998) |
|---|---|
| encephalitis viruses, tick-borne | A subgroup of the genus flavivirus that causes encephalitis and haemorrhagic fevers and is found in eastern and western europe and the former soviet union. It is transmitted by tick vectors and there is an associated milk-borne transmission from viraemic cattle, goats, and sheep. (12 Dec 1998) |
| epidemic encephalitis | A viral encephalitis occurring epidemically, such as in Japanese B encephalitis, St. Louis encephalitis, and lethargic encephalitis. (05 Mar 2000) |
| equine encephalitis | <veterinary> An acute, often fatal, virus disease of horses and mules transmitted by mosquitoes and characterised by central nervous system disturbances. It is typically caused by one of two arthropod-borne viruses, and their resulting diseases are designated western equine or eastern equine encephalomyelitis; these viruses belong to the family Togaviridae and can also cause neurologic disease in humans. Synonym: equine encephalitis. (05 Mar 2000) |
| experimental allergic encephalitis | <pathology> An autoimmune disease that can be induced in various experimental animals by the injection of homogenised brain or spinal cord in Freund's adjuvant. The antigen appears to be a basic protein present in myelin and the response is characterised by focal areas of lymphocyte and macrophage infiltration into the brain, associated with demyelination and destruction of the blood-brain barrier. Sometimes used as a model for demyelinating diseases, although whether this is entirely justifiable is not clear. (18 Nov 1997) |
| Far East Russian encephalitis | Tick-borne encephalitis (Eastern subtype). (05 Mar 2000) |
| fox encephalitis | Encephalitis in foxes, caused by the infectious canine hepatitis virus, a member of the family Adenoviridae family, and characterised by paralysis and death. (05 Mar 2000) |
| lead encephalitis | A metabolic encephalopathy, caused by the ingestion of lead compounds and seen particularly in early childhood; it is characterised pathologically by extensive cerebral oedema, status spongiosus, neurocytolysis, and some reactive inflammation; clinical manifestations include convulsions, delirium, and hallucinations. See: lead poisoning. Synonym: lead encephalitis, saturnine encephalopathy. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
| adeno-associated virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenoidal-pharyngeal-conjunctival virus | <virology> An icosahedral (20-sided) virus that contains DNA, there are over 40 different adenovirus varieties, some of which cause the common cold. (10 May 1997) |
| adenosatellite virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| african horse sickness virus | A species of orbivirus that causes disease in horses, mules, and donkeys. (12 Dec 1998) |
| african swine fever virus | The lone species of the genus african swine fever-like viruses. The virus causes a fatal disease among domestic pigs in africa and a less virulent infection in europe. The virus is present in soft ticks (ornithodoros moubata), warthogs, or domestic pigs. Originally listed as a species of iridoviridae, the virus exhibits some similarities to poxviridae but its differences warranted placement in a separate genus of an, as yet unknown, family.
