Figure 5

Effect of exogenous D-ribose on membrane potential. (A) Variation of PMF in SCH-R by D-ribose dose with or without CCCP. (B) Variation of PMF in SR-7 by D-ribose dose with or without CCCP. (C) Intracellular concentration of gentamicin in SCH-R and clinical isolates in the presence of 24 mM D-ribose. (D) Intracellular concentration of gentamicin in SCH-R and clinical isolates in the presence of 24 mM D-ribose with or without CCCP. GEN, gentamicin. (E) Percent survival of SCH-R and clinical isolates in the presence or absence of CCCP and 1 MIC gentamicin plus 24 mM D-ribose. GEN, gentamicin. Results are displayed as the mean ± SEM and three biological repeats are carried out. Significant differences are identified (*p < 0.05 and **p < 0.01).
