| encephalitis viruses, japanese | A subgroup of the genus flavivirus which comprises a number of viral species that are the aetiologic agents of human encephalitis in many different geographical regions. These include japanese encephalitis virus (encephalitis virus, japanese), st. Louis encephalitis virus (encephalitis virus, st. Louis), kunjin virus, murray valley encephalitis virus (encephalitis virus, murray valley), and west nile virus. (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) |
| encephalitis virus, japanese | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), which is the aetiological agent of japanese encephalitis found in asia, southeast asia, and the indian subcontinent. (12 Dec 1998) |
| encephalitis virus, murray valley | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), found in Australia and new guinea. It causes a fulminating viraemia resembling japanese encephalitis. (12 Dec 1998) |
| encephalitis virus, st. louis | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), which is the aetiologic agent of st. Louis encephalitis in the united states, the caribbean, and central and south america. (12 Dec 1998) |
| encephalitis virus, venezuelan equine | A species of alphavirus that is the aetiologic agent of equine encephalomyelitis in humans and equines. It is seen most commonly in parts of central and south america. (12 Dec 1998) |
| encephalitis virus, western equine | A species of alphavirus that is the aetiologic agent of equine encephalomyelitis in humans and equines in the united states, southern canada, and parts of south america. (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) |
| japanese b encephalitis | <pathology> An epidemic viral encephalitis that strikes populations in Japan and other East Asian countries, typically in summer months. Symptoms canresemble poliomyelitis, but the disease can also be virtually symptomless. (09 Oct 1997) |
| Japanese B encephalitis virus | A virus of the genus Flavivirus (group B arbovirus) occurring particularly in Japan but probably widespread throughout Southeast Asia; the virus is normally present in humans, especially in children, as an inapparent infection, but may cause febrile response and sometimes encephalitis; it may cause encephalitis in horses and abortion in pigs; wild birds are probably the natural hosts and culicine mosquitoes the vectors. Synonym: Russian autumn encephalitis virus. (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) |
| fox encephalitis virus | A virus causing infectious canine hepatitis in dogs. Synonym: fox encephalitis virus, Rubarth's disease virus. (05 Mar 2000) |
