Effects of heparin pretreatment on association with and invasion into hBMECs by S. pneumoniae. Association rates were calculated by dividing the CFU value obtained at 1 hour after infection by the value for the original inoculum. Invasion rates were calculated by dividing the CFU value obtained at 1 hour after antibiotic addition by the value for the original inoculum. Values are presented as the mean of 6 wells from one of 3 independent experiments. Vertical lines represent the mean + S.E. Statistical differences between groups were analyzed using Mann-Whitney’s U-test. *p < 0.05 and **p < 0.01.
