Abstract

Aspergillus fumigatus infection was recorded in turkey farm of 120 brooding poults. Grossly, air sacs were slightly opaque with few scattered miliary white foci. Lungs were moderately firm and had pin point to pin head sized yellowish white caseous nodular growth throughout the lung parenchyma. Histopathologically, lung granuloma showed necrotic cellular debris, heterophils and long septated fungal hyphae in the center surrounded by macrophages, multinucleated giant cells and aggregates of lymphocytes. Gomori's Methanamine Silver Nitrate staining revealed black coloured fungal hyphae.
