Abstract
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.
