Avian tuberculosis was diagnosed in two young adult female commercial emus (Dromaius novaehollandiae) with granulomatous conjunctivitis. Histologically, the granulomas appeared typical of avian tuberculosis. Caseonecrotic cores were surrounded by a broad ring of palisading epithelioid macrophages and multinucleate giant cells with a moderate admixture of heterophils, lymphocytes, and plasma cells. One conjunctival granuloma had multifocal mineralization. At necropsy, granulomas were also found in visceral organs of both birds. Acid-fast bacilli were demonstrated in all lesions using Ziehl-Neelsen or Fite's stains. Culture confirmed the bacilli to be Mycobacterium avium (complex).
在两只患有肉芽肿性结膜炎的成年雌性商品鸸鹋（Dromaius novaehollandiae）中诊断出禽结核病。组织学上，肉芽肿表现为典型的禽结核病。干酪样坏死核心被一圈宽阔的栅栏状上皮样巨噬细胞和多核巨细胞包围，伴有中等数量的嗜异性粒细胞、淋巴细胞和浆细胞。一个结膜肉芽肿有多灶性矿化。尸检时，在两只鸟的内脏器官中也发现了肉芽肿。使用齐-尼氏染色或菲特氏染色在所有病变中均发现抗酸杆菌。培养证实这些杆菌为鸟分枝杆菌（复合群）。
