Background:
Sputum smear microscopy is the initial and rapid diagnostic technique for tuberculosis. This requires two (spot and morning SM) sputum sample examinations over two days. Collection of two spot samples (SS2) on the same day would reduce the number of visits, time, money and early initiation of treatment.
Methods:
We evaluated same day approach (SS2) against standard (SM) for the diagnosis of pulmonary tuberculosis.
Results:
Out of 658 participants, same day approach could identify 62 cases, whereas standard approach could identify 64 cases. Both the approaches are equally effective (p > 0.05).
Conclusion:
The diagnosis of pulmonary tuberculosis is possible in one day by examining two spot samples.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

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.
