Siadenovirus


Siadenovirus is a genus of viruses, in the family Adenoviridae. Vertebrates serve as natural hosts. There are 11 species in this genus.

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:Siadenovirus carbocapituli, Great [tit adenovirus 3]Siadenovirus cinerei, Psittacine adenovirus 2Siadenovirus gallopavotertii, Turkey adenovirus 3Siadenovirus paridae, Great tit adenovirus 1Siadenovirus ranae, Frog adenovirus 1Siadenovirus raptoris, Raptor adenovirus 1Siadenovirus sanguineae, Psittacine adenovirus 7Siadenovirus spheniscidae, Chinstrap penguin adenovirus 2Siadenovirus stercorariidae, South Polar skua adenovirus 1Siadenovirus uriae, Common murre adenovirusSiadenovirus viridis, Psittacine adenovirus 5

Structure

Viruses in Siadenovirus are non-enveloped, with icosahedral geometries, and T=25 symmetry. The diameter is around 90 nm. Genomes are linear and non-segmented, around 35-36kb in length. The genome codes for 25 proteins.

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment of the viral fiber glycoproteins to host receptors, which mediates endocytosis. Replication follows the DNA strand displacement model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear envelope breakdown, viroporins, and lysis. Vertebrates serve as the natural host.
