This research aimed to detect Mycobacterium tuberculosis (M.tb) from sputum DNA using nanopore sequencing for the prediction of strain lineage and drug susceptibility (DST). METHODS: DNA was isolated from 10 randomly selected sputum samples from pulmonary tuberculosis (TB) patients and sequenced using MinION. Sequence data was analysed using Guppy (v3.4.4), Mykrobe Predictor (v0.7.0), and WIMP. RESULTS: On average 100,000-18,000,000 reads were generated per sputum sample. Strain lineage and DST were predicted with less than 0.2% M.tb DNA in sputum. CONCLUSION: Nanopore sequencing of sputum DNA can be used for diagnosing pulmonary TB and for prediction of strain lineage and DST from sputum.
