【摘要】 本文报道１９９４年－１９９５年大连地区由杆状病毒引起的自然发病和人工感染实验中国对虾组织病理学研究。结果表明，自然发病虾和人工感染的虾组织病理相同，在胃、皮下、类淋巴、造血组织、鳃、中肠、后肠、肝胰腺、心脏等组织器官的上皮细胞、干细胞和结缔组织细胞中都可观察到显著胀大，呈空泡状或被苏木精浓染的细胞核。胃是病理变化出现最早且最严重的器官。在电镜下，胃、甲壳下上皮细胞核中可见大量长２７０～３５０ｎｍ，宽１００～１２０ｎｍ的杆状病毒颗粒，细胞核、线粒体出现胀大，嵴断裂、消失情况。干细胞、上皮细胞和疏松结缔组织细胞为靶细胞。更多还原

【Abstract】 This paper reported the histopathological studies on spontaneously diseased and experimentally infected shrimp of Dalian in 1994-1995. The result shows that there are the same histopathological changes for spontaneously diseased and experimentally infected shrimp. The hypertrophied, hollow nucleus or heavily dyed nucleus by Hematoxylin are observed in epithelial cell, connective tissue cell and stem cell of stomach, cuticular tissue, lymphoid organ, hematopoietic tissue, gill, midgut, postgut, hepatopancreas, and heart and so on. The earliest and severest histopathological changes appears in epidermis of stomach. A great deal of baculovirus of 270～350 nm long and 100～120 nm wide are observed in nucleus of stomach and cuticular epithelial cells. The nuclei and mitochondria hypertrophied and degenerated. The epithelial cells and connective tissue cells and stem cell are target.更多还原
