罗非鱼鱼苗在60d内周期性死亡达100%。濒临死亡的鱼表现出快速的螺旋形游动模式(旋转)，这种综合征通过食人成功地传播给幼稚的罗非鱼鱼苗群体。组织学检查没有发现细菌或寄生虫的证据。感染Bohle虹膜病毒(BIV)的罗非鱼和死于旋转性罗非鱼(ST)综合征的罗非鱼在肾脏和肌肉的组织病理学损害方面有相似之处。从受影响的鱼类体内体外分离病毒未获成功。Barramundiates Calcarifer生物测定表明，该流行性感冒的病原为BIV。
Periodic mortalities reaching 100% over a period of 60 d were observed in fry of tilapia Oreochromis mossambicus. Moribund fish exhibited rapid corkscrew-like swimming patterns ('spinning'), and the syndrome was successfully transmitted via cannibalism to naive populations of tilapia fry. Histology revealed no evidence of bacteria or parasites. Bohle iridovirus (BIV) infected tilapia and those succumbing to 'spinning tilapia' ('ST') syndrome shared similarities in histopathological lesions of kidney and muscle. Virus isolation in vitro from affected fish was unsuccessful. The barramundi Lates calcarifer bioassay indicated that the aetiological agent of the epizootic was BIV.
