These pathogens pose significant global health challenges, particularly in developing countries. Differentiating between MTBC and NTM in clinical specimens is often difficult using conventional acid-fast staining methods, leading to an underestimation of NTM prevalence in TB-endemic regions. This study aims to identify mycobacterial species in sputum samples from patients suspected of having TB, utilizing polymerase chain reaction (PCR) assays and gene sequencing techniques.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We collected 111 sputum samples from patients at Dr. Wahidin Sudirohusodo Central General Hospital, Hasanuddin University Hospital, and Makassar Community Lung Health Center.
