Pathological aspects at lung Aspergillosis in broiler chickens

English. From 10 dead and live broiler chickens 15 days old which were sent to the Pathology laboratory by a farm in Tangerang, 3 of them showed fungal lesions in both the lungs and airsacs. The lung organ of one sample showed very prominent fungal lessions which was indicated by a great change of the lungs, such as dark red in colour, white to yellow nodules covering the surface, and the lung became rough and solid. A microscopic examination revealed chronic granulomatous pneumonia and a large number of vegetative hyphae which were specific for Aspergillosis, characterized by dichotomous branching and septation of the hyphae. The laboratory examination by cultivation using Sabouraud's agar media showed the growth of Aspergillus fumigatus after an incubation for 2 day at 37 degree C.
