Summary. Determination of the pattern of manifestation of pathomorphological changes in the body of cattle, infected with M. avium, as well as the frequency and dependence of damage of internal organs from the poultry housing system, was the purpose of the study. Study of pathomorphological properties, laboratory and intravital studies were carried out in accordance with the recommendations. Pathological and morphological studies of calves reacting to tuberculin showed the presence of changes in internal organs that are not considered specific to tuberculosis. In poultry farms unaffected on tuberculosis, lesions of several organs dotted with characteristic nodules were noted. A direct dependence of damage to the respiratory and gastrointestinal tract from the poultry housing system has been revealed. The absence of pronounced specific tuberculous changes in the internal organs of cattle infected with avian mycobacteria, indicates that this species is capable to weakly activating of antigen-dependent differentiation of immunocompetent organs, causing a latent course of infections and the likelihood of sensitization to tuberculin.
Keywords: tuberculosis, pathomorphological properties, avian mycobacteria, calves, lymph nodes, parenchymal organs, chickens.
