Abstract:
The currently available methods are unable to directly detect dormant forms of Mycobacterium tuberculosis (Mtb) in vivo. The persistence of Mtb in the host body is detectable only in an indirect manner via the immunological response to Mtb-specific antigens. It is commonly recognized that the pathogen prevalently exists in the human body in a latent stage. Additional research efforts focusing on the Mtb dormancy are needed for development of sterilizing drugs, which are necessary to control LTBI and stop TB epidemic. To this end, the in vitro models of Mtb dormancy may be useful. This review briefly describes the phenomenon of Mtb dormancy and its role in the context of tuberculosis as a persistent bacterial infection; then the article characterizes in details the in vitro methods used for modeling the Mtb dormancy in bacterial cultures.

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.

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 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...
