Antimicrobial susceptibility of Omp-deficient E. coli, expressing BpsOmp38 variants.

Two statistical methods (ANOVA and log2 dilution) were used to evaluate the significance of their MIC values. Difference between the two studied groups is statically significant with P2 dilution analysis.aValue in brackets is the MIC value when grown in the presence of antibiotic and clavulanic acid, a β-lactamase inhibitor.*Significantly different MIC values for E. coli expressing BpsOmp38 WT and control E. coli.**Significantly different MIC values for E. coli expressing BpsOmp38 WT and E. coli expressing BpsOmp38Y119A or BpsOmp38Y119F.
