    Abstract: The study was conducted to determine the occurrence of <I>Aspergilllus</I> species among apparently healthy birds in poultry farms. 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. <I>Aspergillus</I> sp. was isolated from 718 (47.87%) of the birds. Six species of Aspergillus were isolated viz: <I>A. fumigatus</I> made up 52.37% (376) of the Aspergillus isolates followed by <I>A. flavus</I> 21.87% (157), <I>A. niger</I> 11.42% (82), <I>A. terreus</I> 8.64% (62), <I>A. restrictus</I> 2.79% (20) and <I>A. ochraceous</I> 2.92% (21). <I>Aspergillus</I> species were isolated throughout the year though with a higher incidence during the rainy season compared to the dry season.
