| hepatitis b virus, duck | A DNA virus that closely resembles human hepatitis b virus. It has been recovered from naturally infected ducks. (12 Dec 1998) |
|---|---|
| hepatitis b virus, woodchuck | An orthohepadnavirus causing chronic liver disease and hepatocellular carcinoma in woodchucks. It closely resembles the human hepatitis b virus. (12 Dec 1998) |
| hepatitis C virus | A non-A, non-B RNA virus causing post-transfusion hepatitis; it appears to be a member of the family Flaviviridae. (05 Mar 2000) |
| hepatitis delta virus | A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis b and chronic hepatitis. Officially this is classified as a subviral satellite RNA (RNA, satellite). (12 Dec 1998) |
| hepatitis D virus | A small "defective" RNA virus, similar to viroids and virusoids, that requires the presence of hepatitis B virus for replication. The clinical course is variable but is usually more severe than other hepatitides. Synonym: hepatitis delta virus. (05 Mar 2000) |
| hepatitis e virus | A positive-stranded RNA virus species in the genus calicivirus, causing enterically-transmitted non-a, non-b hepatitis (hepatitis e). (12 Dec 1998) |
| hepatitis virus, duck | An enterovirus with high mortality that attacks ducklings 3 days to 3 weeks old. (12 Dec 1998) |
| serum hepatitis virus | The type species of the genus orthohepadnavirus which causes human hepatitis b and is also apparently a causal agent in human hepatocellular carcinoma. The dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum. (12 Dec 1998) |
| non-A, non-B hepatitis virus | Term used to group any of a number of viruses, other than A or B, which cause hepatitis in humans. (05 Mar 2000) |
| duck hepatitis virus | A DNA virus of the genus Hepadnavirus, in the family Hepadnaviridae, causing virus hepatitis of ducks. (05 Mar 2000) |
| bovine virus diarrhoea virus | A virus of the genus Pestivirus, in the family Togaviridae, causing bovine virus diarrhoea; New York, Oregon, and Indiana strains of the virus are recognised. Synonym: mucosal disease virus. (05 Mar 2000) |
| acute infectious nonbacterial gastroenteritis | An epidemic, highly communicable but rather mild disease of sudden onset, caused by the epidemic gastroenteritis virus (especially Norwalk agent), with an incubation period of 16 to 48 hours and a duration of 1 to 2 days, which affects all age groups; infection is associated with some fever, abdominal cramps, nausea, vomiting, diarrhoea, and headache, one or another of which may be predominant. Synonym: acute infectious nonbacterial gastroenteritis. (05 Mar 2000) |
| arthritis, infectious | Arthritis caused by bacteria, rickettsiae, mycoplasmas, viruses, fungi, or parasites. Bacterial arthritis is frequently caused by staphylococcus aureus, streptococcus pneumoniae, haemophilus influenzae, and neisseria gonorrhoeae. Viral arthritis is less common than bacterial arthritis and may be a manifestation of such viral diseases as mumps, rubella, hepatitis, etc. (12 Dec 1998) |
| avian infectious encephalomyelitis | <veterinary> A disease of very young chicks caused by a picornavirus and characterised by tremor, ataxia, somnolence, and finally death. Synonym: epidemic tremor. (05 Mar 2000) |
| bone diseases, infectious | Bone diseases caused by pathogenic microorganisms. (12 Dec 1998) |
