[2][3] Shrimp and insects serve as natural hosts.

[4][1] Viruses in Penstylhamaparvovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry.

Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis.

The virus exits the host cell by nuclear pore export.
