Adhesion, invasion, and intracellular endothelial cells assay. Confluent endothelial cell obtained from umbilical cord veins were infected with 10⁷ CFU and the percentage of bacterial cells able to adhere (A–C), invade (D–F) and persist intracellularly (G–I) is represented according CC, agr functionality and methicillin resistance. Results are expressed as the percentage of the initial inoculum recovered. Bars and error bars indicate the mean and standard deviations of at least three independent experiments. Only significant p-values are shown.
