Objectives:
To evaluate the role of smoking as a risk factor for the development of pulmonary tuberculosis.
Materials And Methods:
A total of 111 sputum smear-positive patients of pulmonary tuberculosis and 333 controls matched for age and sex were interviewed according to a predesigned questionnaire.
Results:
The adjusted odd ratio of the association between tobacco smoking and pulmonary tuberculosis was 3.8 (95% confidence interval, 2.0 to 7.0; P value, < 0001). A positive relationship between pack years, body mass index and socioeconomic class was also observed.
Conclusion:
There is a positive association between tobacco smoking and pulmonary tuberculosis.

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...
