Erythroparvovirus

Erythroparvovirus is a genus of viruses in subfamily Parvovirinae of the virus family Parvoviridae.[1][2] Primates serve as natural hosts. There are currently seven species in this genus including the type species Primate erythroparvovirus 1. Diseases associated with this genus include fifth disease and skin lesions.[3][4]

Structure

Viruses in Erythroparvovirus are non-enveloped, with icosahedral and Round geometries, and T=1 symmetry. The diameter is around 18-26 nm. Genomes are linear, around 6kb in length.[3]

Life cycle

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. Primates serve as the natural host. Transmission routes are oral and respiratory.[3]

gollark: Based on my limited experience of low level things, and C++'s poor design, C++ use → suffering.
gollark: Perhaps it was, but one which happened to get written into religious books somehow.
gollark: 17% of known gods/theomorphic entities are currently in containment at Site 922-G.
gollark: Yeees, it sounds kind of outside the context they had at the time.
gollark: Fascinating. Where does Christianity say this?
