Atadenovirus is a genus of viruses, in the family Adenoviridae.

[1][2] The genus contains the following 10 species:[2] Viruses in Atadenovirus are non-enveloped, with icosahedral geometries, and T=25 symmetry.

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.

The virus exits the host cell by nuclear envelope breakdown, viroporins, and lysis.
