“…In the present case, white to yellow tubercles were also noted in liver, spleen, gizzard and lung. Microscopic view of the lesions revealed classical formation of tubercles with macrophages, epitheloid cells, giant cells, lymphocytes and an outer fibrous capsule with a central caseous core as reported previously [24] . However, fibrous capsule formation was not clear in liver and spleen.…”

A male Long-legged buzzard with a gunshot wound on his left wing was presented for treatment. However, the bird died shortly after, and then the routine necropsy was performed. At necropsy, numerous white-to-yellow nodular lesions sizing several mm to 1 cm in diameter were noted in liver, spleen, gizzard and lung. Microscopic examination of the nodules in lung and gizzard revealed classical formation of tubercles characterized by a caseous core surrounded by epitheloid cells, multinucleated giant cells, heterophils, macrophages, and outer fibrous capsule. Fibrous capsule formation was vague in tubercles located in liver and spleen. Acid fast bacteria were shown by Ziehl-Neelsen staining. Based on the observations a diagnosis of avian mycobacteriosis was made. This report indicates that avian tuberculosis might be an important disease in free living animals in Turkey as in other places, and more attention might be needed to monitor the disease.

“…Птиця, інфікована Mycobacterium avium complex, може хворіти безсимптомно, тому туберкульоз у неї часто первинно діагностується вже після загибелі, та є причиною зниження чисельності її поголів'я, і, навіть, зникнення окремих видів (Salamatian et al, 2020;Shopland, Barbon, Cotton, Whitford, & Barrows, 2020;Liakhovych et al, 2020;Ledwoń et al, 2018;Liakhovych et al, 2018;Kaboudi, Amara, & Bouzouaia, 2017;Maysoon, S. Abbas, 2016;Özen, Karaman, Dag, Karakurt, & Akbulut, 2016;Kriz, Makovcova, Skoric, Huml, & Pokorny, 2015). В якості класичних патоморфологічних ознак туберкульозу птиці у вітчизняних нормативних документах визначають печінкові та селезінкові гранульоми, казеозний некроз кишкової стінки, казеозну пневмонію (Yatsenko et al, 2015).…”

The results of the study of macroscopical changes in the structural components of the heart and the walls of vessels of different caliber in domestic and ornamental birds that died from tuberculosis are presented. The object of the study was the forms of cardiovascular pathologies in generalized poultry tuberculosis.The aim of the study is to identify and classify macroscopical changes in the heart and wall of bloods vessels in generalized poultry tuberculosis. Materials and research methods. The work was done at the Department of Normal and Pathological Morphology of KhSZA. The following methods were used: pathological autopsy, its analysis, macro-microscopic examination of the heart and wall of bloods vessels using weak-optical lenses, thanatogenetic analysis. 18 adult birds of different species with a comprehensively established diagnosis of "Tuberculosis avium" were studied: pheasants (n = 5), peacocks (n = 3), quail (n = 7), chickens (n = 3).Result of the research. The following cardiac pathologies were diagnosed: cardiac tamponade, pericarditis (constrictive and exudative-constrictive with obliteration of the pericardial cavity); myocarditis; areas of ischemia with an area of damage from 10 % to 50 % or more. Using weak-fold optical lenses in the myocardium of individual birds, miniature scars were detected, located partially perivascular (diagnosed with cardiosclerosis, fibrosis with a diffuse structure, focal hypertrophy of preserved areas of the myocardium). Vascular pathologies differed in complexity and intensity. Ornamental birds were diagnosed with aortic sclerosis, a complication of atherosclerosis (thrombosis, hemorrhage into a disintegrated atheroma), rupture of the aorta and other vessels, hemorrhages, hematomas, anemia, ischemia, thrombosis of mesenteric vessels, thrombophlebitis.
