Membrane vesicles (MVs) from RC85‐T cells can protect β‐lactam‐susceptible RC85 from ampicillin‐induced growth inhibition. The growth‐inhibiting concentration of ampicillin was 32 μg/ml. The data represents means and SEMs for at least three independent experiments. (a) the representative growth profiles of β‐lactam‐susceptible RC85 cells in the presence of growth‐inhibiting concentrations of ampicillin and MVs were calculated from bacterial counts of cultures (CFU‐ colony forming units) taken at different time points (ampicillin, 30 h). (b) CFU of RC85 cells in medium without any antibiotics were used as a positive control and taken as 100%, from which the corresponding CFU were determined. The data were presented as means and SEMs of three independent experiments. ****p < 0.0001
