The steady dead generation and time that was caused by the isolated virus was certain by chicken embryo which was inoculated on seven or nine days . the histopathological changs of the infectious stunting syndrom were studied by the way of ordinary paraffin section and he dying . the experimental result were as follows : the test proved that the changes of the chicken embryo were different in different stage . the chicken embryo dead in a week after it inoculated . the body was dropsy and hemorrhage . dead before it hatched out , the embyo body were dropsy , pale and slime . the liver was yellow and swolled , gallbladder ( vesica fellea ) was filled with bile . bursa and glandula thymus analosis . the kindey dropsy . bowel lamina were humble , dilatation . gas and yellow foam were filled the bowel . histopathological changes were that , in early stage , obvious changes of liver and kindey were dropsy , hemorrhage and necrosis . two types eosinophilic intranuclear inclusion bodies including large round and little granular were present in cells of the above organs . the obvious changes of bursa were dropsy , adverse folliiculated growth and little lymphocytes proliferating , 19 - 21 days chicken embryo , one or two big empty vacuoles were prensent in cells of liver and kindey . the number of the folliculi was growing , the vacuoles between cells were larger 胆囊充盈、其内充满稀薄的胆汁；法氏囊、胸腺萎缩，肠道扩张、肠壁菲薄、内充满气体及黄色泡沫状物；肾脏肿大。病理组织学变化方面，早期肝脏、肾脏、肠主要以出血、水肿和坏死为主，且肝细胞核及肾小管的上皮细胞核内均发现有核内包涵体，包涵体呈嗜酸性，为大型圆形包涵体或不规则的颗粒状；法氏囊则以水肿、滤泡发育不良、小型淋巴细胞数量增多为主。 19 21日龄鸡胚肝细胞、肾小管上皮细胞的胞浆内出现1 2各大的空泡，法氏囊滤泡数目增多细胞间有较大空隙。
