Abstract:
Limited access to diagnostic services and the poor performance of current tests result in a failure to detect millions of tuberculosis cases each year. An accurate test that could be used at the point of care to allow faster initiation of treatment would decrease death rates and could reduce disease transmission. Previous attempts to develop such a test have failed, and success will require the marriage of biomarkers that are highly predictive for the disease with innovative technology that is reliable and affordable. Here, we review the status of research into point-of-care tests for active tuberculosis and discuss barriers to the development of such diagnostic tests.

Pulmonary Tuberculosis IV
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 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...
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.

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...
