Join Us For the Biggest Party Ever

Plus One: includes your host

Iridovirdae Virus

Big image


  • Large
  • Linear, double stranded DNA
  • 150000-280000 nucleotides long
  • The structure is why concatamers are formed during replication

Before joining the party....

  1. The virus entered the host cell through endocytosis.
  2. The release of nucleic acid occurs, and the capsid is open. The virus then penetrated the cell.
  3. The viral DNA was transcripted to the hosts RNA polymerase II.
  4. The parent DNA was used as a template.
  5. Progeny DNA was transported to the cytoplasm were concatamers are formed.
  6. The concatamers were then packaged into virons (complete infection of the host), and exited by budding or the rupture of the cell membrane or wall.

And that is how we got this great big Iridovirus party! The host will thank us later for this extravagant party.


  • Iridovirus (Small iridescent insect virus) (invertebrates)
  • Chloriridovirus (large iridescent insect virus) (insects)
  • Lymphocystivirus (Lymphocystis disease virus) (fresh and marine fish)
  • Ranavirus (frog virus) (amphibians and reptiles)

*With a plus one of the host for each*


For more guests, there must be more transmitting occurring.

The Iridoviruses can be transmitted through water, birds (feathers), nets or cannibalism.

After transmittion it takes 7-10 days for insects to show symptoms (pigment) and three weeks or more until death

Ideal Location of Transmittion

Virus thrives in bother invertebrates and vertebrate hosts. The virus thrives in wet or moist enviroments. Only infect cold blooded hosts.

Medical Disclaimer

Although the iridoviruses are hard to treat because of the transmission factors, and the rapid rate of replication, the KHV vaccine has been studied to help particularly fish with fighting this virus.


  • Vaccines
  • Immune System

*Fight off any organism that poses a threat to our party*
