Abstract

Long-term antiviral chemotherapy using the nucleoside analogue ganciclovir was undertaken with the aim of eliminating hepadnaviral covalently closed circular (CCC) DNA from the livers of ducks that were congenitally infected with the duck hepatitis B virus (DHBV). Twenty-four weeks of ganciclovir therapy caused a substantial reduction in viremia, intrahepatic viral DNA replicative intermediates, and viral core proteins. Unfortunately, ganciclovir therapy did not substantially affect CCC DNA or viral RNA levels, and the treatment resulted in an increase in the intrahepatic expression of the viral envelope proteins, pre-S and S. By the completion of therapy, the viral envelope proteins had ass..
