Two hundreds of layer chickens were sampled from 100.000 layer hens of different ages that showing clinical signs and gross lesions from different farms in Sharkia Governorate from January to April-2008. Aspergillus spp. were isolated and identified morphologically on cultural basis. Morbidity rate was reached 40% and mortality rate more 7%. Clinical signs were mainly respiratory characterized by gasping, dyspnea and accelerated breath. The most common gross lesions were caseated nodules distributed in lung, air sacs, intestine, heart and liver. Microscopic picture revealed granulomatous lesions with or without hyphae. Those lesions represented by caseated nodules, numerous inflammatory cells mainly heterophils, lymphocytes, macrophages and giant cells.The nodules were encapsulated with thin connective tissue capsule.The fungal hyphae appared as branching thread-like either at the periphary or inside the organs parenchyma. Control of aspergillosis in our present study illustrated that there was no curative treatment for aspergillosis.
