Iridovirus

Genus of viruses

Iridovirus is a genus of viruses in the family Iridoviridae. Arthropods serve as natural hosts. Currently, only two species are placed in this genus. Invertebrate iridescent virus 6 (IIV-6) was recognised as the type species until such a designation was abolished. IIV-6 is hosted by mosquitos and usually causes covert (inapparent) infection that reduces fitness. The remaining species Invertebrate iridescent virus 31 (IIV-31) is hosted by isopods and causes patent (apparent) infection characterised by blue to bluish-purple iridescence and a shortened lifespan.
