This study aims to validate TBpore, a novel bioinformatic pipeline for clustering TB transmission isolates using Oxford Nanopore Technology (ONT) data and comparing it against conventional Mycobacterial Interspersed Repetitive-Unit Variable Number (MIRU-VNTR) typing and Illumina sequencing.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methodology\/Principal findings<\/jats:title>\n<jats:p>This retrospective case-control study included 58 clinical isolates from two TB outbreaks in Canada, previously characterized by public health investigations and MIRU-VNTR typing. DNA extraction and sequencing were performed on both Illumina and ONT platforms. Illumina data were processed using Clockwork and psdm, while Nanopore data were analyzed with TBpore. SNP distances were used to compare clustering results across methods, with clusters defined by SNP distance thresholds of \u22645 and \u226412. Both sequencing methods showed a high degree of concordance in clustering results. All isolates from the <jats:italic>M. africanum<\/jats:italic> outbreak clustered within the defined SNP thresholds, consistent with MIRU-VNTR and epidemiological data. In the <jats:italic>M. tuberculosis<\/jats:italic> outbreak, 20 out of 21 isolates clustered similarly across methods, with one exception. Within outbreak pairwise SNP distances were lower with Nanopore.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusion\/Significance<\/jats:title>\n<jats:p>ONT sequencing and the TBpore pipeline offer an accurate alternative to Illumina technology for TB molecular epidemiology. This study suggests potential increased clustering sensitivity with Nanopore technology, warranting further validation on larger datasets with robust epidemiological
