The upper respiratory tract surfaces, the palatine and pharyngeal tonsils and associated lymph nodes of 32 tuberculin reactor cattle were examined pathologically and bacteriologically. Tuberculous lesions were observed histologically in the palatine tonsils of five animals and in both the palatine and pharyngeal tonsils of a sixth. Mycobacterium bovis was cultured from the tonsils of four of these animals and from the palatine or pharyngeal tonsils of a further eight cattle in which no lesions were observed. The upper respiratory tract surfaces of 10 animals were M bovis-positive.
对32头结核菌素反应阳性牛的上呼吸道表面、腭扁桃体、咽扁桃体及相关淋巴结进行了病理和细菌学检查。组织学观察发现，5头牛的腭扁桃体有结核病变，第6头牛的腭扁桃体和咽扁桃体均有结核病变。从其中4头牛的扁桃体以及另外8头未观察到病变的牛的腭扁桃体或咽扁桃体中培养出了牛分枝杆菌。10头牛的上呼吸道表面牛分枝杆菌检测呈阳性。
