Aquamavirus

Aquamavirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Seals and bears serve as natural hosts. Only one species is in this genus: Aquamavirus A.

Structure

Viruses in Aquamavirus are nonenveloped, with icosahedral, spherical, and round geometries, and T=pseudo3 symmetry. The diameter is around 30 nm. Genomes are linear and nonsegmented, around 6.7 kb in length.

Lifecycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis. Replication follows the positive-stranded RNA virus replication model. Positive-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by lysis, and viroporins. Seals and bears serve as the natural hosts.
