Fig. 3: Collateral drug sensitivities can be targeted to limit the growth of drug-resistant variants of M. tuberculosis.

a–d Dose–response curves for selected drug-resistant variants and the drug-susceptible parent against selected antibiotics. Strain names and candidate mutations are listed below each dose-response. Dose-response curves are the results of a single biological replicate from a representative experiment (n > 4 independent experiments). The Gompertz model was used to fit growth data. e–h Time kill assays of selected drug-resistant variants and drug-susceptible variants against sub-inhibitory concentrations (i.e. 0.3× MIC of drug-susceptible parent strain). OD600 data is the mean ± range of biological duplicates from a representative experiment (n > 2 independent experiments). Assays were started at an OD600 of 0.005, and OD600 was determined on stated days. DMSO solvent control graphs are included in Supplementary Fig. 5.
