FIG 2.
Comparison of growth inhibition curve characteristics of the WT, ΔspoT, and spoT*strains with various antibiotics (AMO [0.125 μg/ml], CLA [0.125 μg/ml], MET [0.5 μg/ml], TET [0.25 μg/ml]). Data are the means ± standard errors of the means from three independent experiments. The significance of the difference between the WT and ΔspoT strains was determined using the paired Student's t test. *, P < 0.05; **, P < 0.01.
