Antimicrobial susceptibility of identified periodontal bacteria by disk diffusion tests.

Inhibition zone values: susceptible (S), intermediate (I), and resistant (R). “I” indicates that the result should be considered equivocal. Disk diffusion tests were repeated for each strain 2 times. Antibiotics: penicillin (P), ciprofloxacin (CIP), azithromycin (AZM), clindamycin (CD), tetracycline (TE), dicloxacillin (DCX), ampicillin (AMP), trimethoprim-sulfamethoxazole (SXT), amoxicillin (AML), amoxicillin + clavulanic acid (AUG), and metronidazole (MTZ).
