An outbreak of mycotic tracheitis was observed in 8000 2-month-old, female White Leghorn birds. The birds were showing difficult respiration and there was mortality of 7-8 birds daily in the flock. On post-mortem examination of the affected birds, the trachea was found to be occluded with a white caseous mass. Microscopically hyphae were found invading the tracheal epithelium, cartilage and serosal layer along with infiltration of macrophages and lymphocytes. Aspergillus fumigatus was isolated in pure culture from the trachea. The birds responded to oral copper sulphate treatment. The ubiquitous occurrence of the organism and the conditions of the harvesting season have been found to be responsible for the outbreak of the disease.
在8000只2月龄的雌性白来航鸡中观察到霉菌性气管炎的爆发。这些鸡表现出呼吸困难，鸡群中每天有7至8只鸡死亡。对患病鸡进行尸检时，发现气管被白色干酪样物质堵塞。显微镜检查发现菌丝侵入气管上皮、软骨和浆膜层，同时伴有巨噬细胞和淋巴细胞浸润。从气管中分离出纯培养的烟曲霉。这些鸡对口服硫酸铜治疗有反应。已发现该病原体的普遍存在以及收获季节的条件是导致该病爆发的原因。
