Fig. 2.

Growth inhibition of F. tularensis, Y. pestis and B. pseudomallei by WLBU2, WR12 and LL37. Bacterial cultures (1–2 × 10⁶ c.f.u. ml^− 1) were cultured overnight in BHI with twofold dilutions of the peptide. Graphs show percentage inhibition in bacterial growth (y-axis) upon treatment plotted as a function of peptide concentration (x-axis) for F. tularensis (a), B. pseudomallei (b) and Y. pestis (c). The data shown are the mean of three independent experimental trials; error bars are the sd.
