Expression levels of genes involved in antibiotic efflux and influx during tazobactam and gentamycin treatments. (A) Expression of efflux genes, (B) expression of influx genes. Expression levels of the genes were compared with those of WT (PCN033). 33-TZP/PCN033 indicates the expression levels in PCN033 during tazobactam treatment compared with those in untreated PCN033; K-TZP/PCN033 indicates the expression levels in the Δppk mutant during untreated PCN033.K-GEN/PCN033 indicates the expression levels in the Δppk mutant during gentamycin treatment compared with those in untreated PCN033.***p < 0.000, **p < 0.01, *p < 0.05.
