Antimicrobial Activity of the Essential Oil ofPlectranthus neochilusagainst Cariogenic Bacteria

This work used the broth microdilution method to investigate the antimicrobial activity of the essential oil obtained from the leaves of Plectranthus neochilus (PN-EO) against a representative panel of oral pathogens. We assessed the antimicrobial activity of this oil in terms of the minimum inhibitory concentration (MIC). PN-EO displayed moderate activity against Enterococcus faecalis (MIC = 250 μ g/mL) and Streptococcus salivarus (MIC = 250 μ...
