摘要
对用羊泰勒虫单一种人工感染的试验羊进行了病理学观察。结果显示 ,试验羊的可视黏膜苍白 ,皮下脂肪胶样水肿 ,全身淋巴结、心、肝、脾、肺和肾均有不同程度肿胀 ;实质器官组织变化的主要特征为明显的增生和巨细胞结节形成 ;淋巴结的窦内皮与网状细胞明显增生 ,甚至形成团块和条索 ;淋巴与网状内皮细胞中可见到裂殖体 ;脾还可见到坏死结节 ;肾小球毛细血管内皮细胞和间质细胞也明显增生 ;肝窦内皮的增生特别明显 ,甚至形成细胞条索 ;与淋巴结、脾、肾一样 ,肝小叶内同样有巨细胞结节形成 ,在上述巨细胞结节中均可在细胞浆中发现裂殖体 ;大脑中主要表现血管内皮与小胶质细胞增生。
Two sheep were infected experimentally with Theileria luwenshuni by subcutaneous injection respectively. Pathological changes were observed in many organs and tissues of the animals. The (lesions) consisting of enlargement of lymph nodes and subcutaneous edema were found at necropsy. The (liver) was generally enlarged, yellowish and frequently mottled. White spots of various sizes were seen in the (renal) cortex. The principal microscopic founding was proliferation of reticuloendothetial cell in lymph nodes, spleen, liver, kidney, cerebrum and elsewhere. Koch’s bodies can be found in cytoplasm of giant cell nodules. At the same time, the necrotic changes were seen evidently in the spleen.
