Chloriridovirus is a genus of viruses, in the family Iridoviridae.[1] Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as natural hosts. There are currently five species in this genus including the type species Invertebrate iridescent virus 3. Diseases associated with this genus include: yellow-green iridescence beneath the epidermis (early mosquito larval stages are most susceptible to infection). Death rates are highest in the fourth instar.[2][3] Viruses within this genus have been found to infect mosquito larvae, in which they produce various iridescent colors.[4]

Structure

Viruses in the genus Chloriridovirus are enveloped, with icosahedral and Polyhedral geometries, and T=189-217 symmetry. The diameter is around 180 nm. Genomes are linear, around 135kb in length. The genome codes for 126 proteins.[1][2]

Life cycle

Viral replication is nucleo-cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the DNA strand displacement model. Dna templated transcription is the method of transcription. Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as the natural host.[1][2]

gollark: We can only hope that people move to IPv6 soon. Maybe the increasing prices for IPv4 will help.

gollark: The point is that if you have *no* public IP you can't (usefully) port forward.

gollark: It has become a thing because IPv4 addresses are increasingly expensive.

gollark: <@151391317740486657> Carrier grade NAT. Basically, an extra layer of NAT in front of your router, so you don't have a public IP address.

gollark: I should really read the docs more. I was just using it to write ™ more easily on my laptop, but this is great.
