Sensitivity of K. pneumoniae K7(ΔGT-1), K7(ΔGT-2), and K7(ΔwcaJ) to GH-K3. (A) Spot and plaque forming assays. Five μl of GH-K3 solutions were spotted onto freshly seeded lawns of K. pneumoniae K7(ΔGT-1), K7(ΔGT-2), and K7(ΔwcaJ) for 6 h at 37°C before observation (top). Meanwhile, the sensitivity of K. pneumoniae K7(ΔGT-1), K7(ΔGT-2), and K7(ΔwcaJ) to GH-K3 were determined by plaque assays (bottom). K7 was used as a control. (B) Adsorption efficiency. The adsorption efficiency of GH-K3 binding to K. pneumoniae K7(ΔGT-1), K7(ΔGT-2), and K7(ΔwcaJ) were determined. ∗ and ∗∗ significant differences at P < 0.05 and P < 0.01, respectively. Data represent the mean ± SEM of triplicate experiments.
