Abstract

The susceptibility protocol established in this study takes into account that complex media are capable to buffer H2O2 which otherwise may adulterate test results. Furthermore, we demonstrate that clinical isolates of Staphylococcus aureus showed a higher resistance against H2O2 than Streptococcus pyogenes after 30 mins of incubation but not after 24 h.

Keywords: H(2)O(2); Hydrogen peroxide; Microdilution susceptibility test; Reactive oxygen species; Staphylococcus aureus; Streptococcus pyogenes.
