Comparative growth curves representing the drugs augmenting efficacy of punicalagin against S. typhimurium. A Time kill curve of S. typhimurium for ampicillin with and without punicalagin. Blue: Growth control no ampicillin/punicalagin; Red: punicalagin (500 μg/mL); Grey: Sub-inhibitory concentration of ampicillin (0.3 μg/mL); Yellow: Sub-inhibitory concentration of ampicillin (0.3 μg/mL) with punicalagin (500 μg/mL), (B) Time kill curves of S. typhimurium for aztreonam with and without punicalagin. Blue: Growth control, no aztreonam/punicalagin; Red: punicalagin (30 μg/mL); Grey: Sub-inhibitory concentration of aztreonam (0.05 μg/mL); Yellow sub-inhibitory concentration of aztreonam (0.05 μg/mL) with punicalagin (30 μg/mL)
