Avihepadnavirus viruses , in the family Hepadnaviridae [1] [1] hepatitis , hepatocellular carcinomas (chronic infections), and cirrhosis .[2] [3]
Taxonomy
[ edit ]
The genus contains the following species:[4]
Structure
[ edit ]
Viruses in the genus Avihepadnavirus are enveloped, with spherical geometries, and T=4 symmetry. The diameter is around 42 nm. Genomes are circular, around 3.2kb in length. The genome codes for 7 proteins.[1] [2]

Life cycle
[ edit ]
Viral replication is nucleo-cytoplasmic. Replication follows the dsDNA(RT ) replication model. DNA-templated transcription, specifically dsDNA-RT transcription, with some alternative splicing mechanism is the method of transcription. Translation takes place by ribosomal shunting . The virus exits the host cell by budding, and nuclear pore export. Birds serve as the natural host. Transmission routes are parental, sexual, and blood.[1] [2]
