| Australian X encephalitis | A severe encephalitis with a high mortality rate occurring in the Murray Valley of Australia; the disease is most severe in children and is characterised by headache, fever, malaise, drowsiness or convulsions, and rigidity of the neck; extensive brain damage may result; it is caused by the Murray Valley encephalitis virus (genus Flavivirus). Synonym: Australian X disease, Australian X encephalitis. (05 Mar 2000) |

| bacterial encephalitis | Encephalitis of bacterial aetiology. Synonym: encephalitis pyogenica, purulent encephalitis, suppurative encephalitis. (05 Mar 2000) |
| bovine spongiform encephalitis | <pathology> A neuro-degenerative disease found in domestic cattle which is related to a number of other similar diseases found in other animal species, including humans. The most well-known of these other diseases are scrapie, found in sheep, and Creutzfeldt-Jakob Disease, found in humans. The family of diseases is caused by an abnormally-configured protein called a prion. The function of the protein in its normal configuration is not certain. The diseases are similar to Alzheimer's disease in humans, except the progressive loss of brain function is more rapid. (09 Oct 1997) |
| bunyavirus encephalitis | Encephalitis of abrupt onset, with severe frontal headache and low-grade to moderate fever, caused by members of the genus Bunyavirus (Bunyaviridae family); infections also occur in rodents, lagomorphs, and domestic animals. Synonym: California encephalitis. (05 Mar 2000) |
| California encephalitis | Encephalitis of abrupt onset, with severe frontal headache and low-grade to moderate fever, caused by members of the genus Bunyavirus (Bunyaviridae family); infections also occur in rodents, lagomorphs, and domestic animals. Synonym: California encephalitis. (05 Mar 2000) |
| van Bogaert encephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
| varicella encephalitis | Encephalitis occurring as a complication of chickenpox. (05 Mar 2000) |
| vernal encephalitis | 1. (Central European subtype) tick-borne meningoencephalitis caused by a flavivirus closely related to the virus causing the Far Eastern type; it is transmitted by Ixodes ricinus, also by infected raw milk, especially that of goats. Synonym: biundulant meningoencephalitis, Central European tick-borne fever, diphasic milk fever, Russian spring-summer encephalitis (Western subtype). 2. (Eastern subtype) tick-borne encephalitis, a severe form of encephalitis caused by a flavivirus, a virus belonging to the Flaviviridae family, and transmitted by ticks (Ixodes pertulcatus and I. Ricinus). Synonym: Russian tick-borne encephalitis. (05 Mar 2000) |
| Central European tick-borne encephalitis virus | One of the virus's of the tick-borne encephalitis complex of group B arboviruses (genus Flavivirus); the causative agent of tick-borne encephalitis (Central European subtype). (05 Mar 2000) |
| Mengo encephalitis | An encephalitis occurring in Africa, due to the Mengo strain of encephalomyocarditis virus, a member of the Picornaviridae. (05 Mar 2000) |
| Russian autumn 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) |
| Russian autumn 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) |
| Russian spring-summer encephalitis virus | An arbovirus of the genus Flavivirus that occurs in Central Europe and the USSR in two subtypes, causing two forms of encephalitis in humans: tick-borne encephalitis (Central European subtype) and tick-borne encephalitis (Eastern subtype); the vectors are ticks of the genus Ixodes. Synonym: Russian spring-summer encephalitis virus, tick-borne virus. (05 Mar 2000) |
