摘　　要：为了研究肉鸡气管阻塞的发病机制,试验以临床自然发病肉鸡的肺脏和气管为病料,通过常规石蜡切片、H.E.染色、剖检观察其病理变化。结果表明:气管阻塞发病肉鸡的气管环充血、出血,气管、支气管内有黄白色干酪样物质阻塞,阻塞多发生在支气管与肺部相连处。气管黏膜充血、出血,并有炎性细胞浸润,上皮细胞严重脱落;肺脏出血、淤血明显;细支气管阻塞,阻塞物主要为脱落的上皮细胞、红细胞及渗出的纤维和蛋白。说明发病鸡出现了较严重的组织损伤,并伴有炎性反应。To study the pathogenesis of broiler tracheal obstruction, the lungs and trachea from naturally diseased broilers were used as pathologi- cal materials, and then the pathological changes were observed through routine paraffin sections, H.E. staining, and dissection. The results showed that hyperemia and hemorrhage were seen in the tracheal ring, white -yellow caseous substances obstructed the trachea and bronchi, and the obstruction mostly occurred in the connected place of the bronchi and lungs. Hyperemia and hemorrhage were found in the tracheal mu- cosa with the infiltration of inflammatory cells, and the epithelial cells exfoliated seriously. Hemorrhage and congestion were seen obviously in the lungs. The pulmonary bronchiolar was obstructed, and the stoppers were mainly the exfoliated epithelial ceils, blood ceils, as well as the exuded fiber and protein. The results indicate that more severe tissue damage occurs in the diseased broilers, which is accompanied by the inflammatory reaction.
