Growth curves of the recipient, transconjugant and revertants in the presence or absence of VAN. Overnight bacterial cultures were diluted 100-fold in fresh THB broth with (Right) or without (Left) 1 mg/L VAN. The culture was incubated at 37 °C and the turbidity was measured at an optical density of 620 nm (OD₆₂₀) at each time point. The values were the mean of three independent experiments with standard error, each experiment was performed in triplicate
