Terengganu, Terengganu (MALAYSIA) <p style="text-align: justify;">In this study, various concentrations of ethanolic extracts of propolis (EEP) ranging from 0.03 to 1.0 mg/&micro;L were tested against <em>Staphylococcus aureus</em> (ATCC25923)<em> in vitro </em>employing the disk diffusion technique. EEP showed significant antimicrobial activity against <em>S. aureus</em> with MIC of 0.06 mg/&micro;L (p&lt;0.005) and minimal bactericidal concentration (MBC) of 0.13 mg/&micro;L (p&lt;0.005). This finding suggests a potential use of propolis as an alternative treatment method in combating infections caused by <em>S. aureus</em> that have posed a problem in healthcare settings in Malaysia.</p> https://journalofchemistry.org/paper/714/ antimicrobial activity Malaysian propolis against Staphylococcus aureus
