Brief Report


Members of the family Iridoviridae are animal viruses that infect only invertebrates and poikilothermic vertebrates. Invertebrate iridovirus 25 (IIV-25) was originally isolated from the larva of a blackfly (Simulium spp., order Diptera) found in the Ystwyth river near Aberystwyth, Wales. IIV-25 virions are icosahedral, have a diameter of ~130 nm, and contain a dsDNA genome of 204.8 kbp, with a G+C content of 30.32 %, that codes for 177 proteins. Here, we describe the complete genome sequence of this virus and its annotation. This is the fifth genome sequence of an invertebrate iridovirus reported.
