We first explored the efficacy of single-molecule nanopore DNA sequencing in the early diagnosis of suspected TB patients and analyzed the advantages in differentiating and diagnosing MTB and non-tuberculous Mycobacteria (NTM).</p><p><strong>Methods: </strong>In this cohort study, we reviewed the clinical data of suspected TB patients admitted from December 1, 2021, through April 15, 2022. All patients underwent 3 - 6 times acid-fast bacilli smear examinations of sputum, all of which were negative. To make a definitive diagnosis, we extracted specimens from the patients and performed specimen culture, Xpert MTB/Rif assay, and single-molecule nanopore DNA sequencing.

The accuracy of single-molecule nanopore DNA sequencing in diagnosing mycobacterial infection (MTB + NTM) was 92.0%, with a sensitivity of 90.5% and a specificity of 100%; the accuracy of diagnosing MTB infection was also 92.0%, with a sensitivity of 87.5% and a specificity of 100%. Single-molecule nanopore DNA sequencing showed an accuracy of 100% in differentiating MTB and NTM. However, the diagnostic accuracy and sensitivity of specimen culture and Xpert MTB/Rif assay were relatively low (≤ 52%) compared to \"specimen culture + Xpert MTB/Rif assay\".
