Influence of Eugenia brejoensis essential oil (EbEO) on some virulence properties of S. aureus. (A) Effects of EbEO on expression of hla using S. aureus 8325-4 derivative strains carrying hla:lacZ. (B) Effects of EbEO on expression of spa using S. aureus 8325-4 derivative strains carrying spa:lacZ. (C) Interference of EbEO on hemolytic activity of S. aureus. (D) Inhibition of EbEO on S. aureus survival on whole blood. * Indicates significant differences in relation to control cells (p < 0.05).
