Penstylhamaparvovirus is a genus of viruses in the subfamily Hamaparvovirinae [1] of the virus family Parvoviridae. [2] [3] Shrimp and insects serve as natural hosts. There is only one species in this genus: Decapod penstylhamaparvovirus 1. [4] [1]
Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediate 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.
Virus classification showing major ranks This is a list of genera of biological viruses. See also Comparison of computer viruses. This is an alphabetical list of genera of biological viruses. It includes all genera and subgenera of viruses listed by the International Committee on Taxonomy of Viruses (ICTV) 2022 release. [1]
The Decapoda or decapods (lit. ' ten-footed ') is a large order of crustaceans within the class Malacostraca, and includes crabs, lobsters, crayfish, shrimp, and prawns.Most decapods are scavengers.
This virus has been classified as Penaeus stylirostris hamaparvovirus. The genome is 4.1 kilobases in length. There are three open reading frames in its genome: [3] a left non structural protein (NS1) of 2001 base pairs (bp), a mid non structural protein (NS2) of 1092 bp and a right capsid protein of 990 bp. NSI appears to be a DNA helicase with ATPase activity.
The name refers to the fact that all dependoviruses, except duck parvovirus and goose parvovirus (both classified as Anseriform dependoparvovirus 1), [3] [4] cannot replicate productively in their host cell without the cell being coinfected by a helper virus such as an adenovirus, a herpesvirus, or a vaccinia virus.

Transmission electron micrograph of the Sin Nombre virus, the virus responsible for the outbreak. The spherical particles are virus bodies (virions). The 1993 Four Corners hantavirus outbreak was an outbreak of hantavirus disease that occurred in the Four Corners region of the US states in Arizona, Colorado, and New Mexico.
