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.

Avian tuberculosis in a free-living Eurasian griffon vulture

Although Mycobacterium spp. often cause disease in domestic birds (chickens and companion birds), there are few data on avian tuberculosis in wild populations, especially in birds of prey. We describe here a case of a young adult female, free-living Eurasian griffon vulture ( Gyps fulvus) that was found dead. Granulomas were grossly evident in the lungs at autopsy, and tuberculosis was suspected. Ziehl–Neelsen staining revealed large numbers of intracellular acid-fast–positive bacteria within granulomas. Examination on Löwenstein–Jensen medium was negative, but mycobacteria growth indicator tube medium results were positive. For the molecular detection of Mycobacterium spp., the primer set IS901F and IS901R was used. Positive results were observed on gel electrophoresis, indicating the presence of Mycobacterium avium subsp. avium DNA. Although tuberculosis is not considered to be a common cause of death in wild birds, it undoubtedly deserves special attention because vultures are generally considered to be a species resistant to a large number of pathogens. Determination of the cause of death of griffon vultures is important for future conservation measures for this sensitive wild species.
