Abstract
Tuberculosis (TB), primarily caused by Mycobacterium tuberculosis (MTB), remains a major global health threat, particularly in developing countries. However, nontuberculous mycobacteria (NTM) are increasingly implicated in pulmonary infections, often mimicking TB clinically and radiologically. Misdiagnosis could cause unsuitable treatment plans and higher morbidity. This research investigates emerging molecular biomarkers that distinguish between MTB and NTM infections, highlighting the clinical significance of accurate identification. N. tuberculosis (NTM) was found in 33 clinical samples using real-time PCR that targeted IS6110 for M. tuberculosis (MTB) and MPT64. Results revealed that 51.5% were MTB-positive, 27.3% NTM-positive, and 21.2% negative for both. The findings underscore the importance of incorporating molecular diagnostics in TB-endemic settings to improve therapeutic outcomes and guide public health strategies.
