OBJECTIVE
To describe a case of nocardial nasal granuloma in a Holstein heifer.
CLINICAL FEATURES
The heifer showed laboured respiration and occasional coughing with granulomatous excrescences on the bilateral nasal mucosa, and a marked leucocytosis with eosinophilia. NECROPSY: Severe granulomatous inflammation with eosinophils, epithelioid cells, giant cells and Nocardia sp obstructed both nasal passages completely.
CONCLUSION
This lesion resulted from chronic infection with Nocardia sp and is distinct from other forms of bovine nasal granuloma, also called atopic rhinitis or chronic granular rhinitis, which we propose should be classified as bovine allergic granular rhinitis. The most appropriate name for the present disease is bovine nasal eosinophilic granuloma.
目的
描述一头荷斯坦小母牛发生诺卡氏菌性鼻肉芽肿的病例。
临床特征
该小母牛表现出呼吸费力，偶尔咳嗽，双侧鼻黏膜有肉芽肿性赘生物，且白细胞显著增多伴嗜酸性粒细胞增多。
尸检
严重的肉芽肿性炎症，伴有嗜酸性粒细胞、上皮样细胞、巨细胞和诺卡氏菌属，完全阻塞了双侧鼻腔。
结论
此病变由诺卡氏菌属慢性感染引起，与其他形式的牛鼻肉芽肿不同，后者也称为特应性鼻炎或慢性颗粒性鼻炎，我们建议应将其归类为牛过敏性颗粒性鼻炎。本病最合适的名称是牛鼻嗜酸性肉芽肿。
