[The virulence factors of Mycobacterium tuberculosis: genetic control, new conceptions]
Abstract:
The problem of Mycobacterium tuberculosis virulence, together with drug resistance, is becoming key for the design of drugs with a new mechanism of action and the production of modern concepts and tuberculosis treatment schemes. The review describes gene complexes and their products, including mycolic acids and global regulatory systems at the level of transcriptional, translational, and post-translational modification, etc. The criteria for selection of virulence/pathogenicity factors that might be used for comparative genomic analysis of strains differing in the degree of virulence were recommended. The experimental approaches and test systems for an adequate estimation of the virulence degree of different strains of M. tuberculosis were analyzed.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
