Cipro oxacin

Antibiotic resistance phenotypes of the strains to 11 antibiotics were determined by disk diffusion (Kirby-Bauer) method according to the standard recommendation of the Clinical and Laboratory Standards Institute criteria [38] . Resistance to daptomycin was also tested using the E-test strip (Lio lchem®, Italy). E. faecalis ATCC 29212 and Staphylococcus aureus ATCC 25923 were used as quality control strains. The antibiotic panels used were as follows: penicillin G (10 units), ampicillin (10 µg), vancomycin (30 µg), tetracycline (30 µg), minocycline (30 µg), cipro oxacin (5 µg), levo oxacin (5 µg), gati oxacin (5 µg), nitrofurantoin (300 µg), gentamicin (120 µg) and linezolid (30 µg) (Mast Group Ltd., United Kingdom).

Antibiotic susceptibility of all isolates to amikacin, ampicillin, amoxicillin/clavulanate, imipenem, cipro oxacin, nitrofurantoin, trimethoprim-sulfamethoxazole (SXT), ceftazidime, cefoxitin and gentamicin (Mast Co., UK) was performed on Muller-Hinton agar plates (Merck Co., Germany) using the disk diffusion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines [17] . E. coli ATCC 25922 was used as the quality control strain. MDR was de ned as non-susceptibility to ≥ 1 agent in ≥ 3 different antibiotic classes [18] .
