Parrot' internal organs pathomorphological features in aspergillosis

Aspergillosis is one of the dangerous infectious diseases. Aspergillosis is a disease of various types of domestic and wild birds and, rarely, mammals. Clinically, it is characterized as acute or chronic mycosis, flowing in the presence of respiratory damage and not only. The purpose of this work is to investigate the pathomorphological features of the internal organs of a parrot with aspergillosis. Research was carried out at the Department of Anatomy and Physiology of the State Agrarian University of the Northern Trans-Urals. The objects of research were the corpses of parrots with an established diagnosis of aspergillosis, acquired in a veterinary clinic at this department. To accomplish the assigned tasks, a complex of anatomical and morphometric research methods was used. Macromorphometric methods consisted in determining the linear parameters of internal organs, their shares, length, width using a millimeter ruler. Fixation of the obtained material and histological studies were carried out according to generally accepted methods. Chronic aspergillosis in parrots is characterized by myocarditis, which is manifested by histologically pronounced edema and the presence of leukocytes. Serous glomerulonephritis was noted in the kidneys. And also there were signs characteristic of chronic heart failure (the liver is compacted, there is venous congestion, on the periphery of the lobules, liver cells are in a state of dystrophy).
