^aMtb was grown in the presence of each detergent or antibiotic. The minimal inhibitory concentration that inhibited 50% of Mtb growth was noted after 7 days. These data are representative of at least two independent experiments each performed in duplicate.

^bΔstf0 + pstf0 contains a kanamycin resistance gene.
