Punavirus Explained

Punavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts. There are four species in this genus.^{[1] [2]}

Taxonomy

The following four species are assigned to the genus:

• Aeromonas virus 43
• Escherichia virus P1
• Escherichia virus RCS47
• Salmonella virus SJ46

Structure

Viruses in Punavirus are non-enveloped, with icosahedral and head-tail geometries. The diameter is around 85 nm. Genomes are circular, around 100kb in length. The genome codes for 100 proteins.^[1]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.^[1]
