Overlapping probes in time from micro-array analysis. The Venn diagrams show the number of significantly up-regulated probes (top row) or down-regulated probes (bottom row) (P-value smaller than 10^-8 and fold changes larger than 2 or smaller than −2) between S. epidermidis-injected versus non-injected, S. epidermidis-injected versus needle puncture and S. epidermidis-injected versus PVP at 6 HPI, 1, 2, 3, 4 and 5 DPI. Data at 4 DPI are based on a biological replica. Pie diagrams represent GO annotation using DAVID bioinformatics resources 6.7 [40, 41] from the overlapping genes (in white) at the representative time points.
