Abstract
Two 8-week old Aseel chicks were presented for necropsy from a native chicken
farm with the history of swollen left eyelid, dyspnoea, off feed, dullness and sudden
death. Gross examination of the carcasses revealed swollen left eye with cheesy exudate
on incision. Lungs revealed severe congestion, with multifocal grey consolidated areas
(1-2 mm diameter) while, the intestinal lumen was clogged by numerous round worms.
Histopathological examination of lungs revealed multifocal granulomatous area with
central necrosis, presence of macrophages, lymphocytes and multinucleated giant cells.
Special staining with Periodic acid Schiff and Grocott-Gomori’s methenamine silver stain
showed the presence of fungal hyphae and spores in the lung lesions. The fungus was
identified as Aspergillus sp. by cultural examination. Intestines revealed numerous cut
sections of worms with eosinophilic and mononuclear cell infiltration and were identified
as Ascaridia galli. Eye lesion had multifocal mild to moderate mononuclear cell infiltration
with osseous metaplasia of scleral cartilage in eyeball. Staphylococcus hyicus was isolated
from the eye exudate by cultural examination. Etiological diagnosis revealed an outbreak
of Aspergillosis, Ascariasis and Staphylococcal blepharitis in the farm.
