刺参体内的新病原——一种球状病毒

A New Pathogen in Sea Cumcumber Apostichopus japonicus——A Spherical Virus

2004年12月中下旬-2005年4月对辽宁沿海地区刺参越冬苗发病严重地区，进行了跟踪调查分析。调查结果显示，2004年刺参越冬苗发病比往年早，来势凶猛，持续时间长，流行面广，具较明显的流行病特征，病症异于往年，发病厂家达50％以上，部分地区超过80％，严重地区80％-90％；从患病参体内分离出2株优势细菌和一种新的球状病毒，经负染和超薄切片在电镜下观察，证实有大量球状病毒存于参体内。

A epidemic survey was carried out on the massive death of sea cucumber Apostichopus japonicus in an overwintering nursery pond in coastal Liaoning from winter in 2004 to spring in 2005. There were many spherical viral granules in different tissues in the diseased individuals, and some bacteria were also observed. The pathogenic, and pathologic studies were performed.
