Brit.

/hɛˈpadnəˌvʌɪrəs/, U.S.

/hɛˈpædnəˌvaɪrəs/

Origin: Formed within English, by compounding. Etymons: hepatitis n., DNA n., virus n.

Etymology: < hepa- (in hepatitis n.) + DNA n. (here treated as though an acronym rather than an initialism) + virus n.

Virology.

Any member of the genus Hepadnavirus or family Hepadnaviridae of enveloped, partially double-stranded DNA viruses which are pathogens of a wide range of mammals and birds, infecting the liver and causing hepatitis (hepatitis B in humans) and (in some cases) hepatocellular carcinoma. Also (in form Hepadnavirus): the genus itself.Hepadnaviruses persistently infect liver cells in the form of covalently closed circular DNA (cccDNA). Their replication involves a viral DNA polymerase with a reverse transcriptase function, which is a target for antiviral therapy.

1982 Jrnl. Virol. 42 135 The hepatitis B-like viruses (human hepatitis B virus, woodchuck hepatitis virus, ground squirrel hepatitis virus, and duck hepatitis B virus) are hepatotropic DNA viruses which have been referred to collectively as ‘hepadnaviruses’.

1991 Sci. Amer. Apr. 51/2 Some understanding of HBV [= Hepatitis B virus] has come from studies of similar viruses, called hepadnaviruses, that cause hepatitislike conditions in animals.

2006 Jrnl. Hepatol. 44 S10/1 HBV is a member of the Hepadnaviridae family, genus Hepadnavirus.
