| 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 | <virology> This represents a form of viral hepatitis that cannot be determined to be hepatitis A, B, C or D through testing. (27 Sep 1997) |
| 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 externa | Inflammation of the serous, or peritoneal, covering of the liver. Synonym: hepatic capsulitis, hepatitis externa, hepatoperitonitis. Origin: peri-+ G. Hepar, liver, + -itis, inflammation (05 Mar 2000) |
| hepatitis, infectious | See Hepatitis A. (12 Dec 1998) |
| hepatitis, infectious canine | An adenovirus infection causing fever, oedema, vomiting, and diarrhoea in dogs, especially puppies. In foxes it causes acute encephalitis with convulsions, paralysis, coma, and death. (12 Dec 1998) |
| hepatitis non-A, non-B | <virology> A virus somewhat similar in size to Hepatitis A but has no antigenic cross reaction with either A or B. Many of the cases are in fact hepatitis C and this was the old term for hepatitis C. (20 Sep 2002) |
| hepatitis, toxic | Acute hepatitis caused by true hepatotoxins such as amanita phaloides toxin, carbon tetrachloride, yellow phosphorus, and a variety of drugs. (12 Dec 1998) |
| hepatitis, viral | Liver inflammation caused by viruses. Specific hepatitis viruses have been labelled a, b, c, d, e, f, and g. While other viruses, such as the mononucleosis (epstein-barr) virus and cytomegalovirus, can also cause hepatitis, the liver is not their primary target. (12 Dec 1998) |
| hepatitis, viral, animal | Viral hepatitis in animals. (12 Dec 1998) |
| hepatitis, viral, human | Viral hepatitis in man. (12 Dec 1998) |
| hepatitis virus, duck | An enterovirus with high mortality that attacks ducklings 3 days to 3 weeks old. (12 Dec 1998) |
| hepatitis viruses | Any of the viruses that cause inflammation of the liver. They include both DNA and RNA viruses as well viruses from humans and animals. (12 Dec 1998) |
| serum hepatitis | <virology> A form of viral hepatitis, known as serum hepatitis, because it is commonly spread through contact with infected blood products (transfusion). May also be spread sexually or from mother to infant. Hepatitis B can cause a much more severe infection than hepatitis A and can occur as an asymptomatic carrier state, a chronic infection or as cirrhosis of the liver. Those at risk (IV drug abusers, health care workers, dialysis patients, transfusion recipients, homosexuals) should be immunised with hepatitis B vaccine. The virus is 42nm diameter, with an outer sheath enclosing inner 27nm core particle containing the circular viral DNA. Aggregates of the envelope proteins are found in plasma and are referred to as hepatitis B surface antigen (HBsAg, previously called Australia antigen). The virus can persist for long periods (and in asymptomatic carriers), association of integrated virus with hepatocellular carcinoma is now well established. (27 Sep 1997) |
