aTET, tetracycline; MIN, minocycline; GM120, gentamicin 120 µg; CP, ciprofloxacin; LEV, levofloxacin; GAT, gatifloxacin. Resistance phenotypes were determined for all antibiotics, except daptomycin, by disk diffusion (Kirby–Bauer) method according to CLSI 2014 guidelines (MastGroupLtd, United Kingdom). Antibiotic concentration for each disk was as follows: Penicillin G (10 units), ampicillin (10 µg), vancomycin (30 µg), tetracycline (30 µg), minocycline (30 µg), ciprofloxacin (5 µg), levofloxacin (5 µg), gatifloxacin (5 µg), nitrofurantoin (300 µg), high level gentamicin-resistant enterococci (HLGRE, 120 µg) and linezolid (30 µg)
