A study was conducted for the comparative assessment and clinical evaluation of two different anti-fungal agents against aspergillosis in GYR falcons. Aspergillosis is the most common fungal infection with highest rate of mortality among birds of prey especially in falcons. GYR falons and hybrid GYR falcons are more susceptible to aspergillosis. Aspergillus genus is an opportunistic pathogen which primarily affects the avian respiratory apparatus, including lungs, air sacs and syrinx and occasionally nervous signs. 24 GYR falcons presented in Doha Falcon Clinic with symptoms like progressive emaciation, weakness, lethargy, inability to fly, poor performance in exercise and training were selected for the study and grouped in to two according to age and body weight. Diagnosis were made by radiographic examination and confirmatory diagnosis were done by endoscopy of abdominal cavity, the lungs and air sac (Coelioscopy). Itraconazole were administered at the dose rate of 15-20 mg/kg q24h for 21 days in group 1 and Voriconozole at the dose rate of 12.5 mg/kg q12h for first three days and continue q24h for 18 days in group 2 with supportive therapy. The birds were re-examined after one month for the effect and recovery of treatment. The birds treated by both therapeutic agents showed positive results and these findings indicated that Itraconazole and Voriconozole can be used against Aspergillosis in GYR falcons as primary treatment with better management practices.
