Etiologic Agents and Diseases Found Associated with Clinical Aspergillosis in Falcons

Abstract

The aim of this study was to describe parasitological, microbiological, and pathological findings associated with the isolation ofAspergillusspecies in 94 clinically diseased captive falcons from Dubai. Concomitant agents and/or diseases were identified in 64 cases, causing either single () or multiple coinfections (). Diagnoses found more often in association with aspergillosis were chronic fatigue and immune dysfunction syndrome (CFIDS) (),Caryosporasp. (),Serratospiculum seuratiinfestation (), cestodiasis (), bumblefoot (), trematodosis due toStrigea falconispalumbi(), trichomoniasis (),Babesia shortti(),Mannheimia (Pastorella) haemolytica(), interstitial hepatitis (),Escherichia coli(), andClostridium perfringensenterotoxemia (). Compared with a control group of 2000 diseased falcons without evidence of aspergillosis, the prevalence ofBabesia shortti, CFIDS,Mannheimia (Pastorella) haemolytica, Escherichia coli, and falcon herpes virus infection was conspicuously higher in association with aspergillosis. These entities may be considered suitable candidates as predisposing factors for the mycosis.
