中文摘要：

对尤氏泰勒虫人工感染的绵羊进行了病理学观察。主要的组织病变：淋巴结充血、出血及淋巴窦网状内皮细胞增生；肺脏出血，间质淋巴细胞和网状细胞增生，肺泡隔增厚；肾小球内皮细胞、血管内皮细胞增生，淋巴网状细胞灶状积累，甚至形成结节；心肌细胞变性、坏死，染色不均；肠道固有膜明显充血、出血；肝细胞颗粒变性，有散在细胞坏死，汇管区和小叶间有淋巴网状细胞增生；瘤胃黏膜下层有散在性出血，肌层见灶状出血。

英文摘要：

Sheep were infected experimentally with Theileria uilenbergi by subcutaneous injection, and the pathology of theileriosis was observed. The results showed that the principal microscopic founding was hyperaemia, hemorrhage and proliferation of reticuloendothelial cell in lymph nodes, proliferation of interstitial lymphocytes and reticular cells in lung, and thickened alveolar septum, proliferation of glomerular endothelial cells and vascular endothelial cells in kidney. Lymph reticulocytes were accumulated into a tubercle in kidney. Cardiac muscle cells showed apomorphosis and uneven dyeing. The tunica propria was obvious hyperaemia and hemorrhage in the intestinal tract. Additionally, the hepatocytes showed granular degeneration and necrosis. Various degrees of haemorrhage were seen in submucosa and muscle layer of rumen.
