Figure 5. Rate of GBS adhesion to and invasion of hBMECs.
GBS strain A909 and its isogenic mutant strains were examined for their adhesion and invasion activities. Adhesion rates were calculated by dividing CFU at 1 h after infection by CFU of original inoculum. Invasion rates were calculated by dividing CFU at 1 h after antibiotic addition by CFU of original inoculum. Data are presented as the mean of sextuplets samples. S.E. values are represented by vertical lines.
