摘要
用猪肺炎支原体人工感染仔猪。发病猪临床表现轻度咳嗽和气喘。尸体剖解可见肺呈心叶、尖叶、中间叶和膈叶边缘胰样变,支气管淋巴结肿胀,切面湿润;右心室肥大、心包积液;肾脏稍肿大,色褐黄;肝脏轻度肿大,色泽较黄。病理组织学变化为细支气管周围有淋巴细胞增生,形成"管套"或结节,肺泡壁上皮细胞变性、坏死;肝细胞、肾小管上皮细胞颗粒变性。
Young pigs were infected with Mycoplasma suipneumoniae artificially. These pigs showed light cough and asthma. Postmortal exanination showed that bronchial lymphnodi swelling, right ventricle room hypertro phia, liver and kidney swelling and lungs tooked like pancreas. The histopathology changes were lymphocytic hyperplasia around hronchioli and formed 'the shape of sleeve'. The alveolar wall epithelial occurred denatur ation and necroses.
