[Prevention of tuberculosis: current approaches to development of vaccines]
Abstract:
This review is focused on recent advances in development of new vaccines for the prevention of tuberculosis. The main reasons for lack of BCG vaccine efficacy in different populations and geographic regions are presented. Design of new vaccines based on live modified strains of Mycobacterium bovis BCG, attenuated strains of Mycobacterium tuberculosis, recombinant proteins and viral vectors is considered in the specific examples. The usage of the heterologous "prime-boost" vaccination strategy against tuberculosis is discussed.

Pulmonary Tuberculosis V
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 progression...

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
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.

Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
