We describe the pathology of gastrointestinal tuberculosis in three cows. Gross lesions were found in the jejunum and ileum in all cases, and were characterized by button-shaped ulcers in the mucosa overlying Peyer's patches and adjacent mucosa. One case had similar changes in the pyloric region of the abomasum. In the affected intestinal segments, marked granulomatous inflammation effaced the lymphoid follicles of Peyer's patches and often extended transmurally. Transmural granulomatous inflammation was also found in the abomasum of one cow. Acid-fast bacilli were identified by the Ziehl–Neelsen method and the lesions were immunolabelled by an anti-Mycobacterium tuberculosis complex antibody. M. tuberculosis var. bovis was isolated in one case. Disseminated tuberculosis and marked lung lesions in all cows suggested that the gastrointestinal lesions were most likely secondary to pulmonary infection.

牛胃肠道结核病的病理学

我们描述了三头奶牛胃肠道结核病的病理。所有病例的空肠和回肠均发现肉眼病变,其特征是在派尔氏斑和邻近粘膜上的粘膜中出现纽扣状溃疡。1例真胃幽门区有类似变化。在受影响的肠段,明显的肉芽肿性炎症消除了派尔氏斑的淋巴滤泡,并经常透壁扩展。在一头母牛的真胃中也发现了透壁肉芽肿性炎症。通过 Ziehl-Neelsen 方法鉴定抗酸杆菌,并通过抗结核分枝杆菌复合体抗体对病变进行免疫标记。结核分枝杆菌变种 在一个案例中,bovis 被隔离。所有奶牛的播散性肺结核和明显的肺部病变表明胃肠道病变最有可能继发于肺部感染。
