Resumo

O objetivo do estudo foi avaliar o efeito dos óleos essenciais de Origanum vulgare L. (OEO) e do carvacrol (CAR) no crescimento de bactérias da orofaringe. Para tanto, foram aplicadas as seguintes técnicas microbiológicas: difusão em ágar, concentração inibitória mínima (CIM) e concentração bactericida mínima (CBM). Na análise estatística, foi aplicado o teste ANOVA, com pós teste de Tukey. O nível de significância adotado foi de 5%. As cepas testadas foram Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 15656, Escherichia coli ATCC 25922 e Klebsiella pneumoniae INCQS 00147. O OEO apresentou atividade antimicrobiana, variando o tamanho dos halos de 21,00 (± 0,20) mm, para E. coli, a 33,56 (± 14,32) mm, para S. aureus. No teste de CIM, o CAR obteve menor concentração para a K. pneumoniae e maior concentração para S. aureus. A CBM mostrou valores semelhantes a CIM. O óleo essencial de Origanum vulgare L. e o carvacrol apresentaram efeito inibitório no crescimento de bactérias da orofaringe.
