Penstylhamaparvovirus is the name of a genus of viruses in the subfamily Hamaparvovirinae[1] of the virus family Parvoviridae.[2][3] Shrimps and insects serve as natural hosts. There is only one species in this genus: Decapod penstylhamaparvovirus 1.[4][1]
Viruses in Penstylhamaparvovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 21-22 nm. Genomes are linear, around 4kb in length.[4]
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 exits the host cell by nuclear pore export. Shrimps and insects serve as the natural host.[4]
