Abstract

In this study , the samples of 263 birds suspected to Aspergillosis were examined by direct microscopy, culture and histopathological methods . Of 263 affected birds , 185 (85.3%), 23 (79.3%), and 12 (70.6%) were infected to pulmonary , ocular , and skin Aspergillosis , respectively. The most frequent aspergillus species were A. fumigatus (70.4%) , and then A. flavus (22.7%) , A.niger (3.6%) , A. terreus (2.3%) , and A. ustus (0.9%) . Chickens were the most affected birds(85%) . Aspergillus flavus was the most frequent pathogenic isolate in canary (61.5%) . Young birds were most involved with pulmonary lesions (96.1%) , whereas the ocular and skin lesions were mainly observed in adults . Regarding to high prevalence of different Aspergillus species in the environment and contaminated feedstuffs , it should be considered to plan a program , to prevent the growth of these pathogens in breeding poultry .
