Dicipivirus


Dicipivirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Dogs and hedgehogs serve as natural hosts. There are two species in this genus.

Taxonomy

The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
  • Dicipivirus acadici; Cadicivirus A1, also called Canine picodicistrovirus
  • Dicipivirus berinro; Cadicivirus B1, also called Hedgehog dicipivirus

Structure

Viruses in Dicipivirus are non-enveloped, with icosahedral, spherical, and round geometries, and T=pseudo3 symmetry. The diameter is around 30 nm. Genomes are linear and non-segmented, around 8.8kb in length. The genome has 2 open reading frames.

Life cycle

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. Dogs and hedgehogs serve as the natural host.
