ABSTRACT
Aspergilosis is a respiratory disease in both confined and free ranging birds, and A fumigatus is the most common etiologic agent followed in frequency by A. flavus and A. niger. Aspergilosis usually manifests in carrier birds as a result of a trigger, like starvation or other stressors. This report deals with the diagnosis of aspergilosis in four out of 56 found death herring gulls (Larus argentatus), plus 500 more weak birds found at Playa Linda Zihuatanejo in the state of Guerrero in Mexico. Post-mortem findings included numerous thoracic yellow nodules and a few green caverns from 2 to 15 mm in diameter in pulmonary tissue. A fumigatus was identified through staining, morphologic and culturing properties as well as microscopic tissue changes of the granulomatous reaction in the pulmonary tissue.
