Percent viability of M. chelonae carrying single prophage McProf (MP) and two prophages BPs and McProf in the presence of varying concentrations of a. AMK and b. TOB. As a positive control, single McProf lysogens were treated with 75 μM acivicin (Aci), a known inducer of whiB7. Graphs represent average values ± SE of the mean with n = 6. The optical density was measured at 570- and 600 nm after addition of 1 μl of AlamarBlue and the percent difference in reduction between antibiotic-treated cells and untreated cells was calculated. Mean percent reduction by M. chelonae that are statistically significant are indicated by an Asterix (Wilcoxon rank sum, p < 0.05). Data is representative of three independent experiments
