应用组织病理学方法,观察患有锦鲤疱疹病毒病(Koi herpes virus,KHV)的鲤Cyprinus carpio组织器官的病理变化。结果表明:鳃小片上皮细胞增生、肿胀、增粗、变性、脱落;脾组织出现弥散性脓疡灶和纤维性变化,毛细血管扩张、充血;肾小管上皮细胞结构紊乱、肿胀,伴有崩裂和坏死,肾小球萎缩,毛细血管扩张、充血,肾间质中局灶性坏死;肝细胞呈玻璃样变,肝间质可见局灶性坏死;肠上皮细胞变性、脱落、坏死。
Histopathological methods were used to observe the pathological changes of Cyprinus carpio tissues and organs of Koi herpes virus (KHV). The results showed that the gill epithelial cells proliferated, swollen, thicken, degenerated and shedding. The diffuse abscess lesions and fibrous changes appeared in the spleen tissues. The capillaries dilated and hyperemic. The renal tubular epithelial cells were disorganized, swollen, Necrosis, glomerular atrophy, telangiectasia, congestion, focal necrosis of the renal interstitium; liver cells were glassy, visible focal necrosis of the liver; intestinal epithelial cells degeneration, loss, necrosis.
