S. aureus induced IL9 gene expression in PBMCs. Levels of IL9 gene expression in PBMCs after 24 h stimulation with culture medium (NS), LPS (1 µg/ml), S. epidermidis (105 CFUs/ml), S. aureus (105 CFUs/ml) and SEB (1 µg/ml) in n = 7 independent experiments. IL9 gene expression in significantly increased upon 24 h stimulation with S. aureus (p < .001) and SEB (p < .01), but not upon stimulation with S. epidermidis and LPS. Levels of gene expression are expressed as fold induction (FI) versus non stimulated conditions, divided by 103. Levels of statistical significance are expressed as *p < .05, **p < .01, ***p < .001 and ****p < .0001
