A case of aspergillosis in a broiler breeder flock having respiratory and nervous system problems caused by Aspergillus fumigatus and Aspergillus niger is documented. Dyspnea, hyperpnea, blindness, torticollis, lack of equilibrium, and stunting were observed clinically. On postmortem examination of the affected birds, white to yellow caseous nodules were observed on lungs, thoracic air sacs, eyes, and cerebellum. Histopathologic examination of lungs and cerebellum revealed classic granulomatous inflammation and cerebellar lesions, necrotic meningoencephalitis, respectively. No lesions were noted in the cerebrum histopathologically. Aspergillus hyphae were observed in stained sections prepared from lesioned organs. Fungal spores and branched septate hyphae were observed in direct microscopy. Aspergillus fumigatus and A. niger were isolated from the inoculations prepared from the suspensions of organs showing lesions.
记录了一例肉种鸡群发生的曲霉病，该病例由烟曲霉和黑曲霉引起，出现了呼吸系统和神经系统问题。临床上观察到呼吸困难、呼吸急促、失明、斜颈、平衡失调和发育迟缓。对患病鸡进行剖检时，在肺、胸气囊、眼睛和小脑发现了白色至黄色的干酪样结节。肺和小脑的组织病理学检查分别显示出典型的肉芽肿性炎症和小脑病变、坏死性脑膜脑炎。大脑组织病理学检查未发现病变。在病变器官制备的染色切片中观察到曲霉菌丝。直接显微镜检查中观察到真菌孢子和分支的有隔菌丝。从显示病变的器官悬液制备的接种物中分离出烟曲霉和黑曲霉。
