FIGURE 1.
Antimicrobial susceptibility and multidrug resistance profiles of cefotaxime-resistant Escherichia coli isolates from food animals in South Korea. (A) Antimicrobial susceptibilities were analyzed by the disk agar diffusion method. GEN, gentamicin; AMK, amikacin; ETP, ertapenem; IPM, imipenem; MEM, meropenem; CFZ, cefazolin; CTX, cefotaxime; CAZ, ceftazidime; FEP, cefepime; FOX, cefoxitin; CIP, ciprofloxacin; NAL, nalidixic acid; SXT, trimethoprim-sulfamethoxazole; TGC, tigecycline; ATM, aztreonam; AMP, ampicillin; PIP, piperacillin; AMC, amoxicillin–clavulanic acid; SAM, ampicillin–sulbactam; CHL, chloramphenicol; TET, tetracycline; R, resistant; I, intermediate resistant; S, susceptible. (B) Multidrug resistance was determined as non-susceptibility to at least one agent in three or more antimicrobial classes. MDR, multidrug resistance.
