Susceptibility toward the antibiotics was classified according to the CLSI (2015) and EUCAST (2016) guidelines. C, chloramphenicol; S, streptomycin; TET, tetracycline; E, erythromycin; FEP, cefepime; CTX, cefotaxim; AK, amikacin; SAM, ampicillin-sulbactam; CIP, ciprofloxacin; TOB, tobramycin; MEM, meropenem. Bold values indicate the number of resistant strains out of total 47, followed by the corresponding the percentage resistant.
