| Popis: | The objective of this work was to evaluate the phytochemical composition and the antibacterial and antibiotic-modulating activities of the essential oils of Eugenia brasiliensis Lam (OEEb) and Piper mosenii C. DC (OEPm) singly or in association with blue LED (Light-emitting diode) light. The antibacterial and antibiotic-modulatory activities of the essential oils on the activity of aminoglycosides were evaluated to determine the minimum inhibitory concentration (MIC, &mu g/mL) in the presence or absence of exposure to blue LED light. The chemical analysis showed &alpha pinene and bicyclogermacrene as major constituents of OEPm, whereas &alpha muurolol was the main compound of OEEb. Both OEEb and OEPm showed MIC &ge 512 &mu g/mL against the strains under study. However, the association of these oils with the blue LED light enhanced the action of the aminoglycosides amikacin and gentamicin. In conclusion, the association of aminoglycosides with the blue LED light and essential oils was effective against resistant bacteria. |
