He·pad·na·vi·ri·dae

(hē-pad'nă-vir'ā-dē),
A family of lipid-containing icosahedral DNA-containing viruses 42 mm in diameter the genome of which consists of a single molecule of noncovalently closed, circular DNA that is partially single stranded and partially double stranded; associated with hepatitis in a number of animal species. In mammals, the principal genus ortho is associated with hepatitis B virus; the genus Avihepadnavirus is associated with disease in birds. Persistent infection is common and is associated with chronic disease and liver cancer.

MHC class I presented T cell epitopes as potential antigens for therapeutic vaccine against HBV chronic infection
Heterogenecity among globally common HBV strains is 104 times greater than other DNA viruses which is due to the fact that members of hepadnaviridae family replicate through an RNA intermediate and RNA reverse transcriptase is known to have a high error rate (Hourioux et al., 2000).

Hepadnaviridae. The viral particle is 42 nm in size and consists of an outer lipoprotein coat and hepatitis B surface antigen (HBsAg), which circulates in the blood in two forms: as a viral particle-bound protein form or as a free, noninfectious protein presenting as 22-nm spherical and tubular particles [3] (see Fig.
