| 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) |

| non-A, non-B, non-C hepatitis | Hepatitis caused by viral organisms other than hepatitis viruses A, B or C. (05 Mar 2000) |
| suppurative hepatitis | Hepatitis with abscess formation; often amoebic in origin. (05 Mar 2000) |
| delta hepatitis | Acute or chronic hepatitis caused by the hepatitis delta virus, a defective RNA virus requiring HBV for replication. The acute type occurs in two forms: 1) coinfection, the simultaneous occurrence of hepatitis B virus and hepatitis delta virus infections, which usually is self-limiting; 2) superinfection, the appearance of hepatitis delta virus infection in a hepatitis B virus carrier, which often leads to chronic hepatitis The chronic type appears to be more severe than other types of viral hepatitis. Synonym: delta hepatitis, hepatitis D. (05 Mar 2000) |
| drug-induced hepatitis | <hepatology, pathology> Inflammation and hepatocellular damage of the liver that is caused by a drug. Some medications may cause inflammation of the liver as a drug side effect or drug toxicity. Drugs that are known to cause hepatitis include acetaminophen, isoniazid, halothane, methyldopa, erythromycin and oral contraceptives. (27 Sep 1997) |
| duck hepatitis virus | A DNA virus of the genus Hepadnavirus, in the family Hepadnaviridae, causing virus hepatitis of ducks. (05 Mar 2000) |
| duck viral hepatitis | An acute, highly contagious disease of young ducklings caused by an enterovirus and characterised by lethargy, spasmodic paddling and rapid death. (05 Mar 2000) |
| infectious canine hepatitis | A disease of dogs, caused by canine adenovirus 1, and characterised by fever, depression, loss of appetite, vomiting, bloody diarrhoea, petechial haemorrhages in the gums, pale mucous membranes, and jaundice. Synonym: hepatitis contagiosa canis, Rubarth's disease. (05 Mar 2000) |
| infectious hepatitis | <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) |
| 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) |
| infectious necrotic hepatitis of sheep | A disease of sheep caused by the bacterium Clostridium novyi, which invades livers damaged by the fluke Fasciola hepatica and causes severe necrosis and death; this disease occurs in nearly all parts of the world, including the U.S. Sometimes called black disease because of the extensive haemorrhages seen on the inner surface of the pelt when it is removed. Synonym: black disease. (05 Mar 2000) |
| oriental cholangio-hepatitis | <radiology> Recurrent pyogenic hepatitis, pyogenic cholangitis, seen in Orient and in Asian immigrants, aetiology: Clonorchis sinensis (?), stones, dilated ducts filled with stones, soft, pigmented stones most likely to be no shadow on ultrasound, stricture, obstruction, abscess, increased incidence of cholangiocarcinomarcinoma Differential diagnosis: sclerosing cholangitis, Caroli disease (12 Dec 1998) |
| transfusion 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) |
| epidemic 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) |
| fulminant hepatitis | <gastroenterology, pathology> A severe and rapidly progressive form of hepatitis accompanied by hepatocellular death and the signs and symptoms of hepatic failure. May be a complication of hepatitis B, hepatitis C or hepatitis D. (05 Jan 1998) |
