| infectious polyneuritis | <neurology, syndrome> Acute infective polyneuritis that results in a form of peripheral neuropathy with temporary loss of movement and sensation due to inflammation of multiple nerves and loss of myelin. The exact cause is unknown but has been associated with an abnormal immune response to viral infection, particularly cytomegalovirus infection, in which there is cell-mediated immunity to a component of myelin. The disease may be autoimmune in origin and complete recovery can take up to six months. Synonym: Guillain-Barre syndrome (12 Jul 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) |
| infectious serositis | A contagious disease of young ducks and turkeys caused by the bacterium Pasteurella anatipestifer and characterised in ducks by ocular and nasal discharges, coughing and sneezing, and incoordination, and in turkeys by dyspnea, droopiness, lameness, and a twisted neck. Synonym: new duck disease. (05 Mar 2000) |

| infectious warts | A keratotic papilloma of the epidermis which occurs most frequently in young persons as a result of localised infection by human papilloma virus, usually types 2 and 4; the lesions are of variable duration, eventually undergoing spontaneous regression, and are both exophytic and endophytic, with hyperkeratosis, parakeratosis, hypergranulosis, koilocytosis, and papillomatosis. Synonym: common wart, infectious warts, verruca simplex, viral wart. (05 Mar 2000) |

| encephalopathy, bovine spongiform | Scrapie-like neurological disorder of cattle. The infection appears to be caused by the consumption of scrapie-infected ruminant-derived protein (prions). (12 Dec 1998) |
| enteric cytopathogenic bovine orphan virus | Former name for early isolates of bovine enteroviruses. Synonym: enteric cytopathogenic bovine orphan virus. (05 Mar 2000) |
| enzootic bovine leukosis | A lymphoid neoplastic disease in cattle caused by the bovine leukaemia virus. Enzootic bovine leukosis may take the form of lymphosarcoma, malignant lymphoma, or leukaemia but the presence of malignant cells in the blood is not a consistent finding. (12 Dec 1998) |
| ephemeral fever virus, bovine | The type species of ephemerovirus causing disease in cattle. Transmission is by haematophagous arthropods and the virus has been isolated from both culicoides and mosquitoes. (12 Dec 1998) |
