Amdoparvovirus is a genus of viruses , in the family Parvoviridae, in the subfamily Parvovirinae. Mustelids (minks, ferrets, and foxes), skunk, and raccoons serve as natural hosts. There are currently only two species in this genus including the type species Carnivore amdoparvovirus 1 (Aleutian mink disease virus). Diseases associated with this genus include: progressive disorder of immune system.

Taxonomy
Group: ssDNA
Structure
Viruses in Amdoparvovirus are non-enveloped, with icosahedral and Round geometries, and T=1 symmetry. The diameter is around 18-26 nm. Genomes are linear, around 4.8kb in length.
Life Cycle
Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA templated transcription, with some alternative splicing mechanism is the method of transcription. The virus may exit the host cell by vesicular trafficking following nuclear pore export or be released following cell lysis. Mustelids, skunk, and raccoons serve as the natural host. Transmission routes are oral and respiratory.
