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.

This study will evaluate subjects with fever and/or rash to determine the percentage of those infected by the Zika, Chikungunya, or Dengue virus. The study will also compare the clinical s...
RATIONALE: Some types of lymphoma or lymphoproliferative disease are associated with Epstein-Barr virus. White blood cells from donors who are immune to Epstein-Barr virus may be an effect...
This research study is evaluating the reactivation of BK virus in patients who have undergone allogeneic hematopoietic-cell transplantation.
The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The o...
The purpose of this study is to examine the HIV virus in the blood and lymphoid tissues of patients taking anti-HIV medications. HIV infection is closely linked to the growth of the HIV v...
West Nile Virus (WNV) is mosquito-borne virus that is endemic in Israel. In 2015, national disease surveillance demonstrated a sharp increase in disease cases, with 149 cases diagnosed.
Powassan virus (POWV) is a tick-borne flavivirus that causes rare, but often severe, disease in humans. POWV neuroinvasive disease was added to the U.S. nationally notifiable disease list in 2001 and ...
Ebola virus (EBOV) neutralizing antibody in plasma may reduce viral load following administration of plasma to patients with Ebola virus disease (EVD), but measurement of these antibodies is complex.
The emergence and spread of Zika virus in the Americas continues to challenge our disease surveillance systems. Virus genome sequencing during the epidemic uncovered the timescale of Zika virus transm...
Epstein-Barr virus is a worldwide disease that can cause a wide range of human diseases, the person will become a lifelong carrier of the virus once infected. To investigate the mechanism of Epstein-B...
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.
An RNA virus infection of rhesus, vervet, and squirrel monkeys transmissible to man.
