摘要
通过对确诊的鸭出血症濒死番鸭组织病理学观察 ,可见其肝、肾、脾、胰腺等实质器官淤血、出血 ,细胞变性、坏死 ,间质中淋巴细胞浸润 ;脾脏白髓内淋巴细胞崩解、消失 ,法氏囊滤泡内淋巴细胞明显减少。表明鸭出血症病毒可导致机体广泛性组织损害 ,尤其以循环系统和淋巴组织受损更为严重 ,这提示鸭出血症病毒可引起鸭免疫功能低下 ,出现继发性免疫缺陷。
The tissues of the ducks infected naturally with duck hemorrhagic disease were observed histopathologically. Hemorrhages, cell degeneration, necrocytosis and lymphocytic infiltration were seen in the liver, kidney, spleen and pancreas. The lymphocytes of white pulps of spleen broke apart and disappeared. The lymphocytes of follicules in bursa decreased conspicuously. The results showed that duck hemorrhagic disease virus(DHDV) caused the decrease of duck immunity and secondary immune defect.
