Immunohistochemistry and bacteriologic culturing were used to detect Mycoplasma bovis in tissue specimens from feedlot calves affected with pneumonia and arthritis. Two herds with 110 Charolais calves and 25 Angus calves were examined. Clinical signs included severe respiratory distress, anorexia, pyrexia, and lameness, which affected nearly a third of the calves. Lung lesions were characterized by numerous abscesses. Synovial lesions of the limbs included pyogranulomatous tenosynovitis, bursitis, and synovitis, particularly in the areas of the carpal and elbow joints. Abscesses in lung and synovial tissues contained accumulations of M bovis antigens, as revealed by immunohistochemistry. The findings of this report indicate that infection with M bovis may result in a pneumonia-arthritis syndrome with pyogranulomatous lesions in calves.
采用免疫组织化学和细菌培养方法，对患有肺炎和关节炎的饲养场犊牛组织标本中的牛支原体进行检测。对两个牛群进行了检查，一个牛群有110头夏洛来犊牛，另一个有25头安格斯犊牛。临床症状包括严重的呼吸窘迫、厌食、发热和跛行，近三分之一的犊牛受到影响。肺部病变的特征是有大量脓肿。四肢的滑膜病变包括脓性肉芽肿性腱鞘炎、滑囊炎和滑膜炎，尤其是在腕关节和肘关节部位。免疫组织化学显示，肺和滑膜组织中的脓肿含有牛支原体抗原积聚。本报告的研究结果表明，牛支原体感染可能导致犊牛出现伴有脓性肉芽肿性病变的肺炎-关节炎综合征。
