Animal model, virology and gene cloning of hepatitis E.
We have developed animal models of viral hepatitis E using cynomolgus and rhesus monkeys. They developed acute biochemical and histological hepatitis after the inoculation of virus particles with identical kinetics and magnitude for the sixth subpassage. Virus particles multiplied in hepatocytes and were excreted into feces via bile. Additionally, a transient viremia was recognized. Molecular cloning of virus gene cDNA was successfully accomplished from two separate libraries (HT3 and NE). These clones were expressed into polypeptides having immunological epitopes, which were used for antibody assay of sera of monkeys and patients with positive results.
