mycobacteriosis

Objective. To compare the species diversity of non-tuberculous mycobacteria (NTM) isolated from patients of phthisiopulmonary institutions in 2018–2019 (“pre-Covid” period) and in 2020–2023 (during the COVID-19 pandemic). Materials and Methods. We identified 937 clinical isolates of NTM, isolated from patients undergoing differential diagnosis of tuberculosis and other respiratory diseases at The National Medical Research Center o Phthisiopulmonology and Infectious Diseases under the Ministry of Health of the Russian Federation (NMRC PhPI) and in other phthisiopulmonological institutions of the Russian Federation in 2018–2019 (“pre-Covid” period, n = 217) and in 2020–2023 (during the COVID-19 pandemic, n = 720).

Mycobacterioses are caused by multiple opportunistic bacteria that are ubiquitous. The incidence rate of nontuberculosis mycobacterial infections (NTM) is rising due to an increased number of immunocompromised patients and advances in diagnosis. …
