Results are means of three different experiments.
^aDD: Disc Diameter of inhibition (halo size) in millimeters, Essentiel.oil 100 μg/disc.
^bMIC: minimum inhibitory concentration (in micrograms per milliliter).
^cIC₅₀: 50% inhibition concentration (in micrograms per milliliter).
^dDD: Cycloheximide (10 μg/disc), was used as positive controls for fungi.
NA: no active.
