Complete genome sequence of invertebrate iridescent virus 22 isolated from a blackfly larva

Members of the family Iridoviridae are animal viruses that infect only invertebrates and poikilothermic vertebrates. Invertebrate iridescent virus 22 (IIV-22) was originally isolated from the larva of a blackfly (Simulium sp., order Diptera) found in the Ystwyth river, near Aberystwyth, Wales, UK. IIV-22 virions are icosahedral, with a diameter of about 130 nm and contain a dsDNA genome that is 197.7 kb in length, has a G+C content of 28.05 mol% and contains 167 coding sequences. Here, we describe the complete genome sequence of this virus and its annotation. This is the fourth genome sequence of an invertebrate iridovirus to be reported.
