【摘要】 在福州地区分离到一种高致病性的白斑病病毒 ,该病毒仅存在于细胞质中 ,完整的病毒粒子有囊膜 ,一端略圆 ,一端稍尖 ,直径约为 80～ 10 0nm ,囊膜与核衣壳之间的间隙约为 2 0～ 2 5nm。该病毒在细胞内不形成包含体 ,但有些可形成封入体。负染观察到的病毒核衣壳呈直杆状 ,但长度和直径相差较大 ,最长的病毒超过 6 0 0nm。这些特征与其它已报道的白斑病病毒有所不同 ,因此暂将它称为“对虾白斑病病毒福州分离株”。更多还原

【Abstract】 A high virulent isolate of White Spot Disease Virus has been got in Fuzhou. The virion is in cytoplasm. Intact virion is enveloped and bullet shaped, d=80-100 nm. There is no inclusion body in cell, but sometime a particular structure named occlusion body (some virions are occluded by membrane) in cytoplasm. Nucleocapsid, observed by negative stain, is rod shaped, and its length and width are various. It is possible that the isolate is different from other isolates of White Spot Disease Virus, so the isolate is named “Fuzhou isolate of White Spot Disease Virus”.更多还原
