Percent viability of M. chelonae carrying single prophage McProf, two prophages BPs and McProf, no prophage, or single BPs prophage in the presence of varying concentrations of a. AMK and b. TOB. As a positive control, single McProf lysogens and non-lysogen cultures 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 of 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
