| 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, 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.

| 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) |
