The results of these tests showed that all bacteria were killed by EEP concentrations approximately equal or higher (2.0% v/v - S. aureus; 10.0% v/v - E. coli) than the respective minimal inhibitory concentrations (MIC). Regarding the susceptibility to propolis, there was a homogeneity of data with the respective time kill curves showing a clear bactericidal effect during 6 to 9 h of exposition.287-294engEscherichia coliPopulation analysisPropolisStaphylococcus aureusSusceptibilitypropolisbactericidal activityescherichia coliminimum inhibitory concentrationnonhumanstaphylococcus aureusArtigo10.1590/S0104-79301997000200005S0104-79301997000200005Acesso aberto2-s2.0-0030783157
