| mouse hepatitis virus | A coronavirus, in the family Coronaviridae, that in the presence of Eperythrozoon coccoides causes fatal hepatitis in newly weaned mice; otherwise causes inapparent infection. (05 Mar 2000) |
|---|
| mouse hepatitis | A form of hepatitis in mice due to synergism between the mouse hepatitis virus and Eperythrozoon coccoides. Synonym: murine hepatitis. (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) |
| mouse mammary tumour virus | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
| mouse parotid tumour virus | <virology> A papovavirus (genus Polyomavirus, family Papovaviridae) which is a DNA tumour virus with very small genome. Polyoma was isolated from mice, in which it causes no obvious disease, but when injected at high titre into baby rodents, including mice, it causes tumours of a wide variety of histological types (hence polyoma). In vitro, infected mouse cells are permissive for virus replication and thus are killed, whilst hamster cells undergo abortive infection and at a low frequency become transformed. It is capable of producing parotid tumours in mice and sarcomas in hamsters as well as tumours in other laboratory animals. Synonym: mouse parotid tumour virus. (22 Sep 2002) |
| mouse poliomyelitis 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) |
| mouse thymic virus | An unclassified ether-sensitive virus, 75 to 100 nm in diameter, that causes necrosis of the thymus in young mice. (05 Mar 2000) |
| Swiss mouse leukaemia virus | A murine leukaemia virus producing leukaemia of the reticulum-cell type with massive infiltration of liver, spleen, and bone marrow. It infects dba/2 and swiss mice. (12 Dec 1998) |
| Theiler's mouse encephalomyelitis virus | A virus in the family Picornaviridae. Synonym: Theiler's original virus, Theiler's virus. (05 Mar 2000) |
| anicteric virus hepatitis | A relatively mild hepatitis, without jaundice, due to a virus; the principal physical signs and symptoms are enlargement of the liver, lymph nodes, and often the spleen, together with headache, continuous fatigue, nausea, anorexia, sudden distaste for smoking, abdominal pains, and sometimes mild fever; labratory tests reveal evidence of hepatitis. (05 Mar 2000) |
| virus A hepatitis | A virus disease with a short incubation period (usually 15 to 50 days), caused by hepatitis A virus, a member of the family Picornaviridae, often transmitted by faecal-oral route; may be inapparent, mild, severe, or occasionally fatal and occurs sporadically or in epidemics, commonly in school-age children and young adults; necrosis of periportal liver cells with lymphocytic and plasma cell infiltration is characteristic and jaundice is a common symptom. Synonym: epidemic hepatitis, hepatitis A, infectious hepatitis, MS-1 hepatitis, short incubation hepatitis, virus A hepatitis. (05 Mar 2000) |
| virus B hepatitis | A virus disease with a long incubation period (usually 50 to 160 days), caused by hepatitis B virus, a DNA virus and member of the family Hepadnoviridae, usually transmitted by injection of infected blood or blood derivatives or by use of contaminated needles, lancets, or other instruments; clinically and pathologically similar to viral hepatitis type A, but there is no cross-protective immunity; HBsAg is found in the serum and the hepatitis delta virus occurs in some patients. Synonym: hepatitis B, serum hepatitis, transfusion hepatitis, virus B hepatitis. (05 Mar 2000) |
| virus C hepatitis | Principal cause of non-A, non-B posttransfusion hepatitis caused by an RNA virus that may be related to Flaviviridae family. Synonym: hepatitis C, virus C hepatitis. (05 Mar 2000) |
| virus hepatitis | Liver inflammation caused by viruses. Specific hepatitis viruses have been labelled a, b, c, d, e, f, and g. While other viruses can also cause hepatitis, their primary target is not the liver. (12 Dec 1998) |
| virus hepatitis of ducks | A disease of very young ducklings, caused by the duck hepatitis virus (family Hepadnoviridae) and manifested as an acute illness of several days followed by death; the principal lesions are an enlarged necrotic liver filled with ecchymotic haemorrhages. (05 Mar 2000) |
| hepatitis A 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) |
