Trachea swabs were collected from a total of 1500 birds in 52 commercial (10% of birds in each poultry farm visited) poultry farms were sampled. Aspergillus sp. was isolated from 718 (47.87%) of the birds. Six species of Aspergillus were isolated viz: A. fumigatus made up 52.37% (376) of the Aspergillus isolates followed by A. flavus 21.87% (157), A. niger 11.42% (82), A. terreus 8.64% (62), A. restrictus 2.79% (20) and A. ochraceous 2.92% (21). Aspergillus species were isolated throughout the year though with a higher incidence during the rainy season compared to the dry season.} }
