HEMOCHROMATOSIS IN CORRUPION (ICTERUS JAMACAII)

Abstract

Hemochromatosis, or iron storage disease, is the most common non-infectious disease in birds whose diet is based on foods rich in iron. The present study aims to report the occurrence of hemochromatosis in a horned owl (Icterus jamacaii), as well as the changes and histopathological findings found. An animal of the species Icterus jamacaii (corrupion) with a history of sudden death was received for necropsy at the Animal Pathology Laboratory of the Federal Rural University of the Amazon (LABOPAT-UFRA) campus Belém, Pará, with a history of sudden death, according to the owner. After macroscopic examination, fragments of the heart muscle, liver, CNS and lung were collected and fixed in 10% buffered formalin. Subsequently, they were cleaved and processed to obtain histological slides stained with hematoxylin-eosin and Perls or "Prussian blue. The slides were evaluated under an optical microscope at magnifications of 5x, 20x and 40x. The anatomopathological findings allowed the diagnosis of hemochromatosis. Diagnosis of hemochromatosis in the wild animal clinic is difficult due to its non-specific clinical signs, and is often carried out at necroscopic examination. It is a non-infectious disease common in birds, mainly bred in captivity, reinforcing the importance of regulating wild animal farms.
