Abstract

A case of mycotic tracheitis in an adult Rhode Island Red bird of about 20 weeks of age is described here. Necropsy revealed multiple circumscribed granulomatous nodules in the lungs and caseous plugs in the trachea. Microscopically there were fungal hyphae penetrating the tracheal mucosa together with a caseative plug having central necrotic mass adhering to the tracheal wall, foci of severe congestion and hemorrhage, fungal granuloma surrounded by mononuclear cell infiltration, giant cell, fungal hyphae and fibrous tissues were recorded. The fungal hyphae were also demonstrated by Grocott's methanamine silver stain.
