We report here a ligation-based spoligotyping that can identify unamplified spacers in membrane-based spoligotyping due to asymmetric insertion of IS6110 in the direct repeat locus. Our typing yielded 84.4% (411/487) concordance with traditional typing and 100% (487/487) accuracy when confirmed by DNA sequencing.
