Abstract
From 2016 to 2016, 85 cultures of non-tuberculous bacteria were isolated in 65 patients in Mari El Republic. Of them, 15 (23.1%) were diagnosed with tuberculosis and received the relevant treatment. In all other cases (76.9%), non-tuberculous mycobacteria were detected in the patients suffering from non-specific respiratory diseases and presenting respiratory complaints. The analysis of age and gender structure of those in whom non-tuberculous mycobacteria were detected showed that elderly people prevailed (from 55 to 64 years old). Cultures of M. intracellulare were the most prevalent among non-tuberculous mycobacteria if they were detected repeatedly in the patients in whom mycobacteriosis was suspected. M. gordonae was prevalent among those in whom mycobacteria were detected only once which could be regarded as carriage or contamination. Mycobacteriosis was diagnosed in 22 out of 65 patients, in whom non-tuberculous mycobacteria were isolated (33.8%). Mycobacterioses were caused by the following species: M. intracellulare (77.3%), M. avium (18.2%), M. kanzasii (4.5%).

Summary
В Республике Марий Эл было выделено 85 культур нетуберкулезных микобактерий от 65 пациентов. Преобладающим видом нетуберкулезных микобактерий в случае их неоднократного выделения у пациентов и подозрения на диагноз микобактериоза оказались культуры вида M. intracellulare. Cultures of M. intracellulare were the most prevalent among non-tuberculous mycobacteria if they were detected repeatedly in the patients in whom mycobacteriosis was suspected. Mycobacteriosis was diagnosed in 22 out of 65 patients, in whom non-tuberculous mycobacteria were isolated (33.8%). Выявление микобактерий (МБ) осуществляет бактериологическая лаборатория (БЛ) Республиканского противотуберкулезного диспансера (РПТД), которая является единственной в РМЭ лабораторией, выполняющей микробиологические и молекулярно-генетические исследования для диагностики туберкулеза и микобактериозов. В последние годы отмечается рост числа штаммов нетуберкулезных микобактерий (НТМБ), выделяемых из диагностического материала пациентов различных групп.
