Hepatitis B virus (HBV) belongs to the family Hepadnaviridae, members of which constitute 2 major extant genera:
Orthohepadnavirus, which infect mammals, and Avihepadnavirus, which infect birds (7).
The Hepadnaviridae family is made up of genera
Orthohepadnavirus and Avihepadnavirus.
The family Hepadnaviridae comprises 2 genera (Orthohepadnavirus and Avihepadnavirus), and viruses classified within these genera have a narrow host range.
The analysis revealed a large number of viral contigs annotated to orthohepadnavirus with <70% nt identity (B.
We used PCR to further study the prevalence of orthohepadnavirus in the 6 bat species; the condition of the samples made serologic assay and pathology impracticable.
Hepatitis B virus (HBV) is a hepatotropic, enveloped and partly double helical DNA virus of genus
orthohepadnavirus in the hepadnaviridae family.
HBV belongs te the genus
Orthohepadnavirus, family Hepadnaviridae.
To nonspecialists, it would then be immediately obvious that Hepatitis A, B, and C viruses are very different entities, belonging to different genera, were their official names Hepatitis A hepatovirus, Hepatitis B
orthohepadnavirus, and Hepatitis C hepacivirus.
