ABSTRACT
Duck hepatitis B virus (DHBV) infected carrier ducks serve as a useful model for testing anti-hepadnavirus drugs. This needs a well characterised duck hepatitis B virus strain. We cloned and sequenced the complete genome of duck hepatitis B virus strain of Indian origin. It was 3021 nucleotides in length and had all the recognisable open reading frames (Polymerase: 20-2530 nucletides, Surface: 693-1787 nucleotides and Core: 2518-412). Using an inoculum of 50 microliters serum containing 1 x 10(11) virus particles/ml, we could infect 80% of one day old ducklings and develop a duck colony.
