Msmeg-PE11 are more resistant to SDS, lysozyme, hydrogen peroxide, low pH and antibiotics treatment when compared with Msmeg-pVV.
The Msmeg-pVV or Msmeg-PE11 were either treated with medium alone or subjected to (a) 0.1% SDS, (b) lysozyme, (c) 5 mM hydrogen peroxide, (d) low pH (5.5 for 24 h), (e) 20 μg/ml ethambutol, (f) 20 μg/ml isoniazid, (g) rifampicin (20 μg/ml), (h) vancomycin (5 μg/ml) and (i) ampicillin (750 μg/ml) treatment. Bacterial CFUs were counted on 7H10 agar plates. Data are representative of mean ± SD of three different experiments.
