There is a scarcity of information concerning prevalence of poultry aspergillosis and other fungal diseases in Zaria and Kaduna areas of Kaduna State, Nigeria. This study was conducted to determine the prevalence of Aspergillus species and other fungi in sick poultry presented to the avian clinic of Veterinary Teaching Hospital of the Faculty of Veterinary Medicine, Ahmadu Bello University Zaria. Data on clinically suspected reported cases of aspergillosis and their corresponding Microbiology results between 1980 and 2008 were reviewed, assembled and summarized. Analysis of the 132 cases of sick birds suspected of aspergillosis revealed 114 (86.4%) Aspergillus and other fungi. Eleven different fungi species ascribed to 9 genera were isolated, Aspergillus spp (45.5%), Candida spp (14.4%), Mucor spp (10.6%), Rhizopus spp (10.6%), Penicillium spp (1.5%) and sterile hyphae (1.5%), Alternaria spp, Absidia spp, and Geotrichum spp each with a prevalence of 0.75%. The month of July and November recorded the highest percentage of disease and fungal isolates. There was also no significant difference (p> 0.05) between the monthly fungal isolation and the corresponding average humidity and rainfall. This study showed that aspergillosis is prevalent in Zaria and Kaduna areas and that the disease occurs throughout the year. Good management practices that include; reduction of stressors, overcrowding and provision of adequate ventilation reduces moldy growth in poultry environment and are recommended for the farmer(s).
