Revisão bibliográfica sobre a atividade antimicrobiana in vitro e determinação da concentração inibitória mínima (CIM) do extrato de Melaleuca alternifolia e de Zingiber officinale frente as cepas de Staphylococcus aureus, Escherichia coli e Candida albicans

Abstract

Essential oils from medicinal plants have been used as alternatives in the treatment of infectious diseases caused by strains of Escherichia coli, Candida albicans and Staphylococcus aureus. Melaleuca is one of the most used plants for medicinal purposes, and its extracted oil has been one of the most used worldwide in the treatment of acnes, infections, among others. Ginger oil has been used as a potent anti-inflammatory, antimicrobial. The resistance of microorganisms to antimicrobials has been a major problem for humanity and has made the studies of essential oils extremely important for potential new drugs. In this work, a literature review was carried out using articles in databases such as Pub Med, Google Scholar, Science and Nature as sources of research, with the objective of evaluating and determining the minimum inhibitory concentration (MIC) of essential oils of Melaleuca and Ginger on Escherichia coli, Candida albicans and Staphylococcus aureus strains. Melaleuca and Ginger essential oils were reported to be effective in inhibiting the microorganisms Escherichia coli, Staphylococcus aureus and Candida albicans. Candida albicans was more susceptible to ginger oil, however, Melaleuca oil showed better activity against the Escherichia coli strain. These results show great potential for the use of essential oils as active pharmaceutical products against these three microorganisms.
