Figure 4

(A) CFU/mL of E. coli BW25113 under different treatments. (B and C) CFU/mL of S. enterica under different treatments. CFU enumeration was obtained by incubation with tobramycin in TSB for 4 hours. (D) CFU/mL of E. faecalis 1 under the same treatments as in B and C. (E and F) CFU/mL of log-phase P. aeruginosa PAO1 (E) along with A. baumannii 2 (F) under different treatment schemes. CFU enumeration was achieved after incubation with ciprofloxacin in TSB for 4 hours. Data: Mean + SD from 3 replicates for all the panels. Statistical analysis was determined by Student’s 2-tailed unpaired t test and 1-way ANOVA. ***P < 0.001, **P < 0.01. Significant difference from other groups unless notified.
