| hepatic porphyria | A category of porphyria that includes porphyria cutanea tarda, variegate porphyria, and coproporphyria. Synonym: porphyria hepatica. (05 Mar 2000) |
|---|---|
| hepatoerythropoietic porphyria | An autosomal recessive disorder in which there is a deficiency or absence of uroporphyrinogen decarboxylase; results in photosensitivity and excessive hepatic production of 8-and 7-carboxylate porphyrins. (05 Mar 2000) |
| South African type porphyria | Porphyria characterised by abdominal pain and neuropsychiatric abnormalities, by dermal sensitivity to light and mechanical trauma, by increased faecal excretion of proto-and coproporphyrin, and by increased urinary excretion of d-aminolevulinic acid, porphobilinogen, and porphyrins; due to a deficiency of protoporphyrinogen oxidase; autosomal dominant inheritance. Synonym: protocoproporphyria hereditaria, South African type porphyria. (05 Mar 2000) |
| squirrel porphyria | Porphyria as an apparently normal metabolic state seen in the Florida fox squirrel (Sciurus niger). (05 Mar 2000) |
| d-aminolevulinate dehydratase porphyria | An inherited disorder in which there is a deficiency of porphobilinogen synthase; d-aminolevulinate levels are elevated, leading to neurological disturbances. Synonym: porphobilinogen synthase porphyria. (05 Mar 2000) |
| symptomatic porphyria | A form of hepatic porphyria (porphyria, hepatic) characterised by photosensitivity resulting in bullae that rupture easily to form shallow ulcers. This condition occurs in two forms: a sporadic, nonfamilial form that begins in middle age and has normal amounts of uroporphyrinogen decarboxylase with diminished activity in the liver; and a familial form in which there is an autosomal dominant inherited deficiency of uroporphyrinogen decarboxylase in the liver and red blood cells. (12 Dec 1998) |
| intermittent acute porphyria | <gastroenterology, haematology> A group of rare inherited metabolic disorders that result from a disturbance in porphyrin metabolism, causing increased formation and excretion of porphyrin or its precursors. It is caused by hepatic overproduction of d-aminolevulinic acid, which has greatly increased urinary excretion and of porphobilinogen, and some increase of uroporphyrin, due to a deficiency of porphobilinogen deaminase. Clinical features: intermittent acute attacks of hypertension, abdominal colic, psychosis, and polyneuropathy, but with no photosensitivity. It is exacerbated by the ingestion of certain drugs such as; barbiturates). Inheritance: autosomal dominant. (20 Sep 2002) |
| ovulocyclic porphyria | Acute episodic exacerbations of porphyria occurring in the premenstrual period. (05 Mar 2000) |
| erythropoietic porphyria | A classification of porphyria that includes congenital erythropoietic porphyria and erythropoietic protoporphyria. (05 Mar 2000) |
| african swine fever | A usually fatal iridovirus infection of pigs, characterised by fever, cough, diarrhoea, haemorrhagic lymph nodes, and oedema of the gallbladder. (12 Dec 1998) |
| african swine fever-like viruses | An unnamed, unclassified genus of DNA viruses with a single species: african swine fever virus. (12 Dec 1998) |
| african swine fever virus | The lone species of the genus african swine fever-like viruses. The virus causes a fatal disease among domestic pigs in africa and a less virulent infection in europe. The virus is present in soft ticks (ornithodoros moubata), warthogs, or domestic pigs. Originally listed as a species of iridoviridae, the virus exhibits some similarities to poxviridae but its differences warranted placement in a separate genus of an, as yet unknown, family. (12 Dec 1998) |
| atrophic rhinitis of swine | A disease manifested by atrophy, shrinkage, and often almost complete disappearance of the turbinate bones, accompanied by distortion of the facial bones, sneezing, and stunting of the growth of young animals; caused principally by the bacterium Bordetella bronchiseptica. (05 Mar 2000) |
| gastroenteritis, transmissible, of swine | A condition of chronic gastroenteritis in adult pigs and fatal gastroenteritis in piglets caused by a coronavirus. (12 Dec 1998) |
| vesicular exanthema of swine | A calicivirus infection of swine characterised by hydropic degeneration of the oral and cutaneous epithelia. (12 Dec 1998) |
