稚鳖粘液性肠炎病的病理形态学研究

Morphopathology of the Mucous Enteritis in Young Soft shelled Turtle

稚鳖 (Pelodiscussinensis)粘液性肠炎病的主要眼观病变是病鳖肛门排出粘液块。组织病理变化主要为肠腺分泌亢进 ,肠上皮细胞脱落 ,肠壁充血 ,肝脏脂肪变性 ,脾脏炎性细胞浸润 ,肾脏肾小管上皮细胞水泡变性 ,肺也有不同程度的病变。电镜下观察 ,发现随着病程的延续肠道的病变相应地加重 ,主要表现为炎性细胞浸润、上皮细胞变性和坏死。

Macroscopically,the mucous enteritis of young soft shelled turtle was characterized by excreting mucous mass from anus. Histologically,pathologic changes were increasing secretion of intestinal glands,abscission of intestinal epithelial cells, hyperemia of intestinal wall,liver fat degeneration,infiltration of inflammatory cells in spleen,vacuolar degeneration of epithelial cells in kidney renal tubule. There were also lesions of different degree in lung. By electron microscope, it was found that,with the progress of the disease,lesions in intestine became evident,manifested as infiltration of inflammatory cell,degeneration and necrosis of the epithelial cells.
