Validation of bath infection model with a known antibiotic. (A) Kaplan?Meier representation of the survival of injured zebrafish embryos bath infected with PAO1 strain at approximately 108 CFU/mL and treated with ciprofloxacin 50 µg/mL or hydrochloric acid 0.2 mM (negative control) 2 hours after infection. (B) Kaplan?Meier representation of the survival of injured zebrafish embryos bath infected with PAO1 strain at approximately 5 × 107 CFU/mL and treated with ciprofloxacin 1 µg/mL or hydrochloric acid 0.5 mM (negative control) 2 hours after infection. Pools of three biologically independent replicates (with 20 embryos) are shown for each survival curve. *** p < 0.001; ** p < 0.01.
