Abstract: The incidence of tuberculosis caused by Mycobacterium bovis, not only the pulmonary form, but also the form developing in the extrapulmonary organs, is also increasing from year to year. Despite the large number of EPTB, TBPLN occupies a leading place among diseases of this type and the study of its pathogenic strains is an urgent task in ensuring the effectiveness of treatment. In this regard, the main purpose of the presented manuscript is to determine the frequency of M. bovis in TBPLN, its effect on the development and course of the disease, as well as the effectiveness of treatment. For this purpose, for the first time, the features of education that occur in patients in peripheral lymph nodes using instrumental methods of ultrasound, computed tomography, and magnetic resonance imaging have been identified. In subsequent studies, 110 patients with peripheral lymph node pathology were diagnosed with TBPLN by detecting mycobacteria in pathological material using general hematological, microbiological and gene-molecular (Gene Xpert) methods. In order to ensure the high effectiveness of drugs used for medicinal purposes, strains of the pathogen were detected using histological, cytological studies, BCG test and specific analyzes such as Diaskintest, Quantiferon test, immunological tests. The study showed that about 80% of patients had M bovis in the overall assessment, 76.4% of patients were sensitive to rifampicin, 9.1% of patients had rifampicin-resistant bacteria, and 14.5% of patients did not have mycobacteria. Therapeutic measures were carried out in 2 different modes, such as standard and individual or with replacement, when all patients were divided into 2 groups. During the period from the 56-day intensive phase of standard treatment to the 84-day intensive phase, a total of 40 patients had a sharp decrease in lymph nodes, elimination of purulent inflammation, and after a while 22 patients in this group had a relapse. In the individual treatment regimen, Levofloxacin and linezolid were used instead of pyrazinamide. While the effectiveness of treatment was achieved in 48 patients of group II after 56 and 84 days of the intensive phase, relapses after a certain time were observed in only 6 patients. When choosing an individual treatment regimen in patients diagnosed with M. bovis, a decrease in relapses to 11.5% is achieved. When M. bovis is detected, an individual scheme of antibacterial treatment of tuberculosis is selected, in which, instead of pyrazinamide, it is recommended to choose one of the reserve lines, depending on the sensitivity of the pathogen to drugs.
