Pathogenesis of Aspergillus fumigatus infection in pigeons in the Sudan

Abstract

The pathogenesis of a pigeon isolate of Aspergillus fumigatus in a local breed of pigeons in the Sudan was tested. The spores inoculated intravenously resulted in an acute disease with 100 % of mortality within six days. At necropsy, pinpoint and miliary lesions were prominent in the liver, spleen, lungs and kidneys. Histopathological examination detected lesions in the liver, heart, lungs, kidneys, spleen and brain. Hyphae and/or spores were encountered in all these Organs. The presence of A. fumigatus was confirmed by reisolation from the liver, lungs and kidneys.
