Study overview illustrating the methods applied to DNA extracted from culture-confirmed M. bovis-positive tissue samples (n = 60) from 57 different African buffalo, selected and included in the study following mycobacterial species identification. After amplifying three target genes (hsp65, rpoB, 16S rRNA), long-read amplicon sequencing was conducted on 56 samples using Oxford Nanopore Technologies (ONT), the Native Barcoding Kit 96 V14, and a single R10.4.1 flow cell. Mycobacterium tuberculosis complex (MTBC) speciation was achieved by amplifying and sequencing the gyrA and gyrB gene targets on 11 randomly selected samples using a single Flongle R10.4.1 flow cell (ONT).
