Effects of antibacterial agents on nontypeable Haemophilus influenzae. Cells invaded by bacteria and then treated with phosphate-buffered saline (PBS) served as the study control. A significant bactericidal effect on each NTHi strains was observed when 1 MIC of GRNX, CAM, or LVFX was used (a) (p < 0.05). However, no bactericidal effect was observed from treatment with AMPC or CDTR-PI (a). Similarly, treatment with 2 MIC of GRNX, CAM, or LVFX also had a significant bactericidal effect (p < 0.05), but when treated with AMPC or CDTR-PI, no bactericidal effect was observed (b). MIC, minimum inhibitory concentration; NTHi, nontypeable Haemophilus influenzae; GRNX, garenoxacin; LVFX, levofloxacin; CAM, clarithromycin; AMPC, amoxicillin; CDTR-PI, cefditoren pivoxil; CFU, colony-forming units. *p < 0.05
