Atividade antibacteriana e moduladora do óleo essencial de Allium sativum L. (Alho)

Abstract

The present study aims to evaluate the antibacterial and modulating activity of the essential oil of Allium sativum L. (OEAs) associated with LED lights. The essential oil was obtained by hydrodistillation and the antibacterial and modulating activity was performed by the gas contact method with the use of yellow, blue and red LED light along with the antibiotics amikacin, ciprofloxacin, gentamicin, norfloxacin, oxacycline and penicillin. The tests were performed in triplicate and submitted to ANOVA statistical analysis with significance test for p <0.05. In the direct antibacterial activity there was no inhibition of the growth of the tested strains and for the OAS + antibiotic + LED lights (modulation of antibacterial resistance) combinations with multi-resistant strains of Escherichia coli 27 and Staphylococcus aureus 358 there was a possible synergism with the antibiotics amikacin, ciprofloxacin, norfloxacin and oxacillin. These results become important in collaboration with future research for new ways of treating diseases caused by multi-resistant bacteria.
