Fig. 2. Relationship between adeJ pump gene expression and resistance to each antibiotics. Relative expression of adeJ efflux pump gene in non-susceptible (NS) group was higher than that of susceptible (S) group to each antibiotics in general. The statistically significant difference was found between S and NS groups to cefepime, cefotaxime, ceftazidime, ciprofloxacin, gentamicin, imipenem, meropenem, piperacillin, piperacillin/tazobactam, ticarcillin/clavulanic acid, tigecycline, and trimethoprim/sulfamethoxazole, respectively. *P < 0.05, **P < 0.001. The error bars represent the standard error of the mean.
