All patients who are undergoing liver biopsy or liver transplantation may participate in this study. For patients undergoing liver biopsy, a small piece of liver tissue will be taken from the sample collected during the scheduled biopsy. For patients undergoing liver transplantation, a small piece of tissue will be collected from the diseased liver that is to be removed.
Our laboratory has a long-standing interest in viruses that affect the bone marrow. Many such viruses also may cause hepatitis. One specific syndrome, post-hepatitis aplastic anemia, suggests that the same agent is responsible for both severe and sometimes fulminant hepatitis as well as profound bone marrow failure. In investigating the role of viruses in these diseases, we require small amounts of liver tissue for molecular studies. We request permission to obtain samples from patients undergoing 1) liver transplantation or 2) liver biopsy at the time of surgery for purpose of virus discovery, including obtaining control samples. For liver transplant samples, tissue will be obtained from the removed organ; in other surgical circumstances, small amounts of tissue will be obtained when the liver is biopsied for other medical indications. No additional risk to the patient should result from either procedure.

A genus of FLAVIVIRIDAE, also known as mucosal disease virus group, which is not arthropod-borne. Transmission is by direct and indirect contact, and by transplacental and congenital transmission. Species include BORDER DISEASE VIRUS, bovine viral diarrhea virus (DIARRHEA VIRUS, BOVINE VIRAL), and CLASSICAL SWINE FEVER VIRUS.
A species of POLYOMAVIRUS, originally isolated from the brain of a patient with progressive multifocal leukoencephalopathy. The patient's initials J.C. gave the virus its name. Infection is not accompanied by any apparent illness but serious demyelinating disease can appear later, probably following reactivation of latent virus.
A species of CORONAVIRUS infecting cats of all ages and commonly found in catteries and zoos. Cats are often found carrying the virus but only a small proportion develop disease. Feline coronavirus and Feline infectious peritonitis virus (FIPV) are virtually the same virus in genetic and antigenetic terms, and are morphologically indistinguishable. Since they only differ in their disease potential (with FIPV causing a more serious illness), they are considered biotypes of each other.
A species of PESTIVIRUS causing systemic infections including BOVINE VIRUS DIARRHEA-MUCOSAL DISEASE and BOVINE HEMORRHAGIC SYNDROME in cattle and some other cloven-hoofed animals. There are several strains and two biotypes: cytopathic (rare) and non-cytopathic. The severity of disease appears to be strain dependent. Cytopathogenic effects do not correlate with virulence as non-cytopathic BVDV-2 is associated only with Hemorrhagic Disease, Bovine.
