Figure 6From: An extracellular Staphylococcus epidermidis polysaccharide: relation to Polysaccharide Intercellular Adhesin and its implication in phagocytosisImpact of 20-kDaPS on endocytosis of S. epidermidis by human macrophages. Bacterial suspensions of non-20-kDaPS producing S. epidermidis clinical strain, preincubated with different concentrations of 20-kDaPS, were added to human macrophages. The number of endocytosed bacteria was counted by serial dilutions of cell lysates on blood agar. All experiments were repeated five times.Back to article page
