Virulence of S. pettenkoferi SP165 and S. aureus SA564 strains in zebrafish embryos. Kaplan–Meier representation of the survival of (A) healthy zebrafish embryos or (B) zebrafish embryos injured in the tail fin at 48 h post-fertilization (hpf) in a bath infected with S. pettenkoferi SP165 or S. aureus SA564 strains at 2.107 CFU/mL grown in exponential phase or “fish water” (negative control). The proportion of surviving embryos (n = 24 for each, indicative of three separate experiments) is used to express the results. Significant difference at ** p < 0.01, **** p < 0.0001, or no significant difference (ns).
