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 [2,8].The Iridoviridae family is divided into four genera,Iridovirus,Chloriridovirus,Ranavirus,and
Lymphocystivirus.
Iridoviruses infect a wide variety of cultured fish [12,26].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 [1,5,10,11,14,17–19,21].However,sequence analysis of the MCP revealed the presence of fish iridoviruses which belong neither to the genus
Ranavirus nor to the genus Lymphocystivirus [9,13].In addition,genetic and phenotypic variants within iridovirus [7,13,25] suggest the possibility of the
presence of diverse variants within the fish iridoviruses.

虹彩病毒是一种二十面体形的大型胞质DNA病毒[24].它的染色体循环扭曲并且末端冗余,具有真核病毒的染色体的典型特点[2, 8].虹彩病毒科分为四个属：虹彩病毒属、绿虹彩病毒属、蛙科病毒属和淋巴囊肿病毒. 虹彩病毒侵染许多饲养鱼类品种[12, 26].多数鱼类虹彩病毒是淋巴囊肿病毒属或蛙科病毒属的成员.而真鲷虹彩病毒属于能引起纤维原细胞或造骨细胞过度增生发育的淋巴囊肿病毒属,其他虹彩病毒属于能引起感染动物全身性疾病并伴随着高发病率和死亡率的蛙科病毒属[1, 5, 10, 11, 14, 17–19, 21].然而主要衣壳蛋白（MCP）序列分析表明鱼类虹彩病毒既不属于蛙科病毒属也不属于淋巴囊肿病毒属[9, 13].此外,虹彩病毒属的遗传和表型变异分析[7, 13, 25] 暗示着鱼类虹彩病毒内存在一个不同变株的可能性.
