The lymphocyte subsets and PPD-antibody in peripheral blood were determined in 72 cases of bacteriological positive pulmonary tuberculosis using monoclonal antibody to anti-T lymphocyte and ELISA assay. The results showed that the percentage of T3 was 52.44 +/- 11.46% and the OD of PPD-antibody was 0.47 +/- 0.27 in initially treated patient group; 40.27 +/- 7.81%, 0.81 +/- 0.17 in chronic carrier group respectively. There were statistically significant difference between the two groups (P < 0.01). The percentage of T3 was significantly larger in 30-59 yr group than in more than 60 yr group among non chronic carriers (55.9 +/- 11.3% vs 44.4 +/- 2.4, P < 0.05). PPD-antibody was strongly associated with extent of lesion in lung.

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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 III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
