| mouse encephalomyelitis | Encephalomyelitis due to the mouse encephalomyelitis virus (a species of Enterovirus) which is not pathogenic in monkeys or in man, but attacks mouse colonies and causes a flaccid paralysis, usually of the hind limbs. Synonym: mouse poliomyelitis, Theiler's disease. (05 Mar 2000) |
|---|---|
| mouse encephalomyelitis virus | A virus of the genus Enterovirus, family Picornaviridae, normally associated with inapparent infections and found in the intestinal tracts of infected mice, occasionally causing mouse encephalomyelitis in experimentally inoculated susceptible mice. Synonym: mouse poliomyelitis virus. (05 Mar 2000) |
| porcine haemagglutinating encephalomyelitis virus | A coronavirus causing vomiting, wasting, and encephalomyelitis in young pigs. (05 Mar 2000) |
| postvaccinal encephalomyelitis | A severe type of encephalomyelitis that can follow the rabies vaccination. Synonym: postvaccinal encephalitis. (05 Mar 2000) |
| herpes B encephalomyelitis | A frequently lethal disease of humans caused by infection with a normally latent monkey herpesvirus. (05 Mar 2000) |
| sporadic bovine encephalomyelitis | A disease of cattle caused by the bacterium Chlamydia psittaci and characterised by fever, depression, excessive salivation, diarrhoea, anorexia, and incoordination. (05 Mar 2000) |
| infectious porcine encephalomyelitis | Porcine polioencephalomyelitis; a disease of swine caused by porcine enterovirus 1 and resembling human poliomyelitis; it is characterised by stiffness, convulsions, paralysis, and prostration, and is widespread in Europe, with most serious losses occurring in Poland and the Czech Republic and Slovakia. Synonym: infectious porcine encephalomyelitis, porcine polioencephalomyelitis. Origin: Teschen, Silisia (05 Mar 2000) |
| infectious porcine encephalomyelitis virus | A picornavirus causing Teschen disease of pigs; the virus is normally a harmless inhabitant of the intestinal tract, but virulent strains cause epizootics of the disease. Synonym: infectious porcine encephalomyelitis virus. (05 Mar 2000) |
| Theiler's mouse encephalomyelitis virus | A virus in the family Picornaviridae. Synonym: Theiler's original virus, Theiler's virus. (05 Mar 2000) |
| theiler's murine encephalomyelitis virus | A species of cardiovirus which causes poliomyelitis in rats. It should not be confused with the strain of encepalomyocarditis virus called encephalomyelitis virus, murine, which is also a cardiovirus. (12 Dec 1998) |
| eastern equine encephalomyelitis | A form of mosquito-borne equine encephalomyelitis seen in the eastern U.S. And caused by the eastern equine encephalomyelitis virus, a species of Alphavirus, which belongs to the family Togaviridae; initial fever and viraemia are followed by signs of central nervous system involvement (excitement, then somnolence, paralysis, and death); the incidence of clinical infection in man is low but case fatality may be high. (05 Mar 2000) |
| eastern equine encephalomyelitis virus | A virus of the genus Alphavirus (formerly group A arbovirus), in the family Togaviridae, occurring in the eastern United States; it is normally present in certain wild birds as an inapparent infection, but is capable of causing eastern equine encephalomyelitis in horses and humans following transfer by the bites of culicine mosquitoes. Synonym: EEE virus. (05 Mar 2000) |
| encephalomyelitis | Inflammation of the brain and spinal cord, usually caused by viral, bacterial, fungal, or parasitic agents. (12 Dec 1998) |
| encephalomyelitis, acute disseminated | An acute or subacute encephalomyelitis or myelitis characterised by perivascular lymphocyte and mononuclear cell infiltration and demyelination. It occurs most commonly following an acute viral infection, especially measles, but may occur without a recognizable antecedent, and formerly occurred as a complication of rabies and smallpox vaccination. (12 Dec 1998) |
| encephalomyelitis, allergic | An experimental demyelinating disease produced in animals by injections of myelin fractions in order to study the relationship between hypersensitivity and the demyelinating diseases. (12 Dec 1998) |
