<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Avihepadnavirus&#039;&#039;&#039; is a genus of viruses in the family Hepadnaviridae. Birds serve as natural hosts. There are currently only two species in this genus including the type species [[Duck hepatitis B virus]]. Diseases associated with this genus include: [[hepatitis]] and [[hepatocellular carcinoma]].<br /> <br /> == Taxonomy ==<br /> The following two species are assigned to the genus:<br /> <br /> * [[Duck hepatitis B virus]]<br /> * [[Heron hepatitis B virus]]<br /> <br /> == Structure ==<br /> Viruses in 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.<br /> <br /> == Life Cycle ==<br /> Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the [[DNA strand displacement]] model. DNA-templated transcription is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Birds serve as the natural host. Transmission routes are fecal-oral and sexual.<br /> <br /> == Clinical Relevance ==<br /> Avihepadnaviruses are of significant clinical relevance as they are associated with diseases such as hepatitis and hepatocellular carcinoma in birds. The study of these viruses can provide insights into the treatment and prevention of these diseases.<br /> <br /> == See Also ==<br /> * [[Hepadnaviridae]]<br /> * [[Hepatitis B virus]]<br /> * [[Hepatitis]]<br /> <br /> == References ==<br /> &lt;references/&gt;<br /> <br /> == External Links ==<br /> * [http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Info&amp;id=10486 NCBI Taxonomy Browser, Avihepadnavirus]<br /> <br /> [[Category:Viral diseases]]<br /> [[Category:Hepadnaviridae]]<br /> [[Category:Animal virology]]<br /> <br /> {{stub}}</div>
