The ∆ exoA strain displayed a mildly significant ( p < 0.05 cefsulodin and ampicillin, p < 0.0005 meropenem) increase in sensitivity to all three antibiotics compared with WT, as determined by a disk diffusion assay, but this does not fully explain the hypersensitivity of chvG or chvI deletion mutants ( Figure 6B ).
