| 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) |
|---|---|
| peliosis hepatitis | A rare condition in which the liver contains very numerous small blood-filled spaces, sometimes lined with endothelium; it may be found incidentally or rupture may cause intraperitoneal haemorrhage. (05 Mar 2000) |
| goose viral hepatitis | An acute, highly fatal disease of goslings and Muscovy ducklings caused by the goose parvovirus and characterised by anorexia, feather loss, and tissue haemorrhages. Synonym: Derzsy's disease. (05 Mar 2000) |
| cholangiolitic hepatitis | Hepatitis with inflammatory changes around small bile ducts, producing mainly obstructive jaundice; may be due to viral infection or bacterial infection ascending biliary tree because of obstruction. (05 Mar 2000) |
| cholestatic hepatitis | Jaundice with bile stasis in inflamed intrahepatic bile ducts; usually due to toxic effects of a drug. (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 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) |
| plasma cell hepatitis | <pathology> A type of chronic active hepatitis that results from circulating auto-antibodies and chronic inflammation of the liver. Symptoms are those of chronic active hepatitis. (27 Sep 1997) |
| MS-1 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) |
| murine hepatitis | A form of hepatitis in mice due to synergism between the mouse hepatitis virus and Eperythrozoon coccoides. Synonym: murine hepatitis. (05 Mar 2000) |
| halothane hepatitis | Hepatocellular damage said to result from the administration of halothane anaesthesia. (05 Mar 2000) |
| hepatitis | <pathology> Inflammation of the liver. (18 Nov 1997) |
| hepatitis A | <virology> A form of viral hepatitis, known as infectious hepatitis, due to its ability to be spread through personal contact with oral secretions or stool. Virus will be shed in the stools of an infected individual 2-3 weeks prior to the onset of any symptoms. Hepatitis A may also be transmitted sexually. Symptoms are similar to those of influenza, but the skin and eyes may become yellow. Recent travel to a third world country is a risk factor. There is no specific treatment but infected individuals should avoid potentially hepatotoxic substances. The virus is a small (27nm diameter) single stranded RNA virus with some resemblance to enteroviruses such as polio. (27 Sep 1997) |
| hepatitis agents, gb | Proposed members of the family flaviviridae. Gbv-b causes hepatitis in tamarins and possibly humans, and is the putative aetiological agent of a non-(a-e) hepatitis, gb hepatitis. (12 Dec 1998) |
| hepatitis a immunization | When immediate protection against hepatitis a (infectious hepatitis) is needed, immunoglobulins are used. Protection is effective only if given within 2 weeks of exposure and lasts but 2-4 months. Immunoglobulins can be used to protect household contacts of someone with acute viral hepatitis and travelers to regions with poor sanitation and high hepatitis a rates, when the traveler has to depart sooner than the vaccines can take effect (about 2 weeks). Travelers can receive the immunoglobulin and vaccine simultaneously and be protected immediately and for longer term. When immediate protection is not needed, hepatitis a vaccines are considered for individuals in high-risk settings, including frequent world travelers, sexually active individuals with multiple partners, homosexual men, individuals using illicit drugs, employees of daycare centres, and certain healthcare workers, and sewage workers. Two hepatitis a vaccines called havrix and vaqta are commercially available in the u.s. Both are highly effective and provide protection even after only one dose. Two doses are recommended for adults and 3 doses for children (under 18 years of age) to provide prolonged protection. (12 Dec 1998) |
