Data are expressed as viability of Mtb in ‘relative CFU (colony forming unit) counts’. A ‘relative CFU count’ was calculated by normalizing the data in each time point with the inoculated Mtb CFU. A cut-off of 0.1 was considered as zero. PBA-group exhibited significantly earlier decline in intracellular Mtb CFU counts after MDM-mediated killing compared to the placebo-group.
