Table 3 Antimicrobial activity of SLB propolis. It was tested three reference strains of three pathogenic agents: a fungus (C. albicans), a Gram-negative (E. coli) and a Gram-positive (E. faecalis) bacterium in a microdilution assay, along with different propolis concentrations. MIC100—minimum concentration capable to inhibit the growth of 100% of the microbes; MFC100 – minimum concentration capable to inactivate 100% of the fungi; MBC100 – minimum concentration capable to inactivate 100% of the bacteria. The experiment was repeated three times and the results are their averages
