The results represent the mean ± standard deviation of the relative expression in qPCR of seventeen differentially expressed genes identified in the microarray analyses with all data (main list), S. aureus (Sa list) or S. epidermidis data (Se list). qPCR were performed with Sa or Se samples or with both Sa an Se samples (All data). A non parametric Wilcoxon test was performed with SAS to identify the differentially expressed genes. ** p-value < 0.05; * p-value < 0.10.
