Abstract
According to the World Health Organization Global Tuberculosis Report, published in 2022, tuberculosis and its drug-resistant forms are on the rise for the first time in recent years. The ability to become immune to anti-tuberculosis drugs is a fundamental feature of the tuberculosis agent. In some cases, tuberculosis develops a transient resistance to antibacterial drugs based on a combination of adaptive biological properties of the mycobacterium without altering the genetic apparatus. This phenomenon is called drug-induced tolerance. Its development is associated with the slowing or altering of bacterial metabolism, increasing the thickness of the cell wall, activation of specific molecular pumps, and removal of medicinal substances from outside the cell. The same and some other mechanisms are involved in the development of another phenomenon drug resistance, which is associated with inherited changes in the genetic apparatus of mycobacterium. The review is devoted to the molecular bases of the interaction of mycobacterium tuberculosis with anti-tuberculosis drugs and its epidemiological significance.
