| hepatitis b 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) |

| 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) |
| infectious hepatitis virus | <virology> An RNA virus (hepatovirus) in the family Picornaviridae, that is the causative agent of viral hepatitis type A. The virus replicates in hepatocytes and is presumed to reach the intestine via the bile duct. Transmission occurs by the faecal-oral route. Synonym: infectious hepatitis virus. (20 Sep 2002) |
| beige mouse | A mouse strain typified by beige hair and lymphadenopathy, reticulum cell neoplasms and giant lysosomal granules in leukocytes. May be the murine equivalent of Chediak Higashi syndrome of man. (18 Nov 1997) |
| mammary tumour viruses, mouse | The type species of mammalian type b retroviruses (retroviruses type b, mammalian) commonly latent in mice. It causes mammary adenocarcinoma when in a genetically susceptible strain of mice and when the appropriate hormonal influences operate. (12 Dec 1998) |
| water mouse | <zoology> Any one of several species of mice belonging to the genus Hydromys, native of Australia and Tasmania. Their hind legs are strong and their toes partially webbed. They live on the borders of streams, and swim well. They are remarkable as being the only rodents found in Australia. Source: Websters Dictionary (01 Mar 1998) |
