Objective To investigate the feasibility of combined ornidazole and pefloxacin for peridontal pathogen in vitro and estimate their antibacterial activities. Methods By the shape of corniform of two inhibition rings
the effect of two drugs was estimated. By the checkerboard method
the fractional inhibitory concentration (FIC) of two drugs was estimated when they were mixed at different concentrations. Results No obvious physical and chemical changes were observed when the two drugs mixed together. The FIC index of Pg
Fusobacterium nucleatum
Pi
Peptostreptococcus and Staphylococcus aureus was 0.312 5
0.375
0.562 5
0.75
1.062 5 and 1.062 5 respectively. Conclusion The two drugs are of good compatibility and of addition effect on anaerobic bacterium
but only pefloxacin is effective on aerobic bacteria.
