摘　　要： 采用常规石蜡切片、苏木精-伊红染色的方法,研究了鲫(Carassius auratus auratus)自然感染圆形碘泡虫(Myxobolus rotundus)后的组织病理变化。结果表明,感染圆形碘泡虫后,在鲫的头部、鳃和体表能形成大小不一的圆形或椭圆形乳白色孢囊,其孢囊为典型的3层结构:外层的结缔组织、双层质膜的外质以及各个发育阶段的孢子或营养体组成的内质。病理切片可见鱼体各组织器官均有不同程度的病变,主要表现为鳃丝粘连、肿胀增生;肝脏发生以肝血窦为中心的透明、空泡变性;肾小管内皮脱落,肾小球萎缩;肠道粘膜层脱落,肌层细胞肿胀病变;脾脏的含铁血黄素增多等异常现象。 The pathological changes of myxosporadiosis naturally infected by Myxoboluz rotundus in crucian carp （ Carassius auratus auratus） were studied by conventional paraffin section and hematoxylin-eosin staining. Results show that many milky white cysts at different sizes form on the head, gill and skin of the infected crucian carp ; the cysts have a typical 3-layer structure ： connective tissue, ectoplasm with double membranes and endoplasm with the spores or trophozoites at different developmental stages. Pathological changes are mainly shown as follows： swollen and proliferated branchial filament in the gill; vacuolation of sinusoid-centric cells in the liver; epithelium necrosis in renal tubules and atrophia in renal glomerulus ; necrosis of intestine mucous layer and swollen degeneration of intestine muscle layer; abnormal increase of hemosiderin in spleen.
