Bacterial invasion time. Nontypeable Haemophilus influenzae (NTHi) entered the cells 2 h after adhering to the cells (a). The maximum invasion was at 6 h (a). There were no differences between the numbers of bacteria invading the cells after 6 h and 8 h (a). Similar results were also observed with Streptococcus pyogenes, which invaded the cells 2 h after cell adhesion (b). The maximum invasion was at 6 h (b). No differences were found between the numbers of cell-invading bacteria after 6 h and 8 h (b). *p < 0.05. N.S., not significant; CFU, colony-forming units
