Iridoviruses are large cytoplasmic DNA viruses with an icosahedral morphology [24]. The genome is both circularly permutated and terminally redundant, which is a unique feature among eukaryotic virus genomes. The Iridoviridae family is divided into four genera, Iridovirus, Chloriridovirus, Ranavirus, and Lymphocystivirus.
Iridoviruses infect a wide variety of cultured fish. Most fish iridoviruses are members either of the genus Lymphocystivirus or of the genus
Ranavirus.While iridoviruses belonging to the genus Lymphocystivirus cause the development of clusters of extremely hypertrophied fibroblasts or osteoblasts called lymphocystis cells, other iridoviruses belonging to the genus Ranavirus cause systemic disease in infected animals and are associated with high morbidity and mortality. However, sequence analysis of the MCP revealed the presence of fish iridoviruses which belong neither to the genus Ranavirus nor to the genus Lymphocystivirus. In addition, genetic and phenotypic variants within iridovirus suggest the possibility of the presence of diverse variants within the fish iridoviruses.
