Abbreviations. C: chloramphenicol; CD: clindamycin; CIP: ciprofloxacin; ERY: erythromycin; FD, fusidic acid; FOX: cefoxitin; PEN: penicillin; SXT: trimethoprim-sulfamethoxazole; TET: tetracycline; CN: gentamicin; KAN: kanamycin; TOB: tobramycin; LNZ: linezolid. Note: the superscript number after each antibiotic and gene indicates the number of strains showing resistance to that antibiotic and harboring that gene, respectively.
