title: Chronic pulmonary interstitial fibrosis in Amazon parrots.
abstract: In the Netherlands, a syndrome affecting several species of older Amazon parrots (Amazona sp.) has been described. This syndrome was characterized as a chronic respiratory disease resulting in exercise intolerance. Pathological examination revealed loss of functional lung tissue, pulmonary interstitial fibrosis, and right heart failure. Haematology revealed an elevated packed cell volume as a result of an increase in erythrocyte size and an increased haemoglobin mass per erythrocyte. In two patients, hypoxia and hypercapnia were demonstrated. The aetiology of this syndrome is currently not known. The microscopic lesions resemble those found in Diffuse Interstitial Fibrosis in humans.
