Adhesion of complemented S. aureus mutants to HaCaT cells. Adherence of S. aureus isogenic mutant NCTC8325–4ΔsdrD complemented with different pMG36e-SdrD variants or pMG36e (empty vector). Adherence was calculated as a percentage of the mean colony-forming unit (cfu/ml) of attached bacteria to the mean cfu/ml of the inoculum. The data represent mean of 3 independent experiments, each with 3 technical repeats. Statistical analysis was performed using one-way ANOVA with Tukey’s multiple comparison test (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001)
