Mean (±SEM) Mab lung burden (log10 CFU) in A) C3HeB/FeJ and B) BALB/c mice, n=5 per time-point, per treatment group, treated with 25mg/kg clofazimine is shown in red. Mean (±SEM) Mab lung burden in the negative control group, administered with phosphate buffered saline (PBS), is shown in grey. Time-point week −1 represents the day following infection with Mab. Time-point week 0 represents the day antibiotic administration was initiated. CFZ-25, 25 mg/kg clofazimine. P-values of PBS vs each treatment group are represented as stars: * represents p ≤0.05; ** represents p ≤0.01.
