A case of acute beak and feather disease complicated with secondary fungal infection was diagnosed in a three-month-old female African Grey Parrot (Psittacus erithacus). Two days before the bird’s death the owners observed its depression and diarrhea with excess urates. Despite symptomatic therapy the bird died after two days. In the course of the autopsy a large focus of fungi in the trachea bifurcation and left main bronchus was discovered. Also visible were strong congestion and areas of hepatization in the left lung, the enlargement of mottled liver and air sacculitis (abdominal air sacs). Histologically, no inclusion bodies in the hepatic cells and no lesions in the proventriculus were observed. Microbiological examination revealed numerous fungi as Aspergillus sp., Streptomyces sp. and Candida sp. In the PCR test presence of Psittacine Beak and Feather Disease Virus was detected. PCR tests for Pacheco’s disease herpesvirus, avian Polyomavirus and Chlamydophila psittaci were negative.
