Abstract(s)
Desde a descoberta dos microrganismos como agentes causadores de doenças no Homem que vários estudos foram levados a cabo com o objetivo de descobrir novas formas de os combater. A introdução de compostos com atividade antimicrobiana marcou uma nova era no combate a doenças o que permitiu a redução da mortalidade e morbilidade, mas o seu consumo intensivo rapidamente conduziu ao aparecimento de resistências.
A falta de soluções perante a patogenicidade dos microrganismos impulsionou o estudo de novas alternativas. Os óleos essenciais que contêm uma variedade de compostos voláteis, como terpenos e fenóis, são conhecidos pelas suas propriedades anti – sépticas e medicinais, usados como antimicrobianos, analgésicos, sedativos e anti – inflamatórios. O objetivo deste trabalho é avaliar a atividade antimicrobiana de 20 óleos essenciais contra bactérias Gram – positivas e Gram – negativas (Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853) e leveduras do género Candida (C. albicans ATCC 10231, C. krusei ATCC 6258 e Candida parapsilosis ATCC 2209).
Since the discovery of microorganisms as pathogenic for human beings several studies were lead with the aim of discovery news forms to stop them. The development of the antimicrobial drugs mark a new era on the combat to diseases which allow to reduce mortality and morbidity, but human misuse quickly caused an increase in antimicrobial resistance. The lack of options for treatment leads to search new alternatives. Essential oils contain a variety of volatile molecules, such as terpenes and phenol, and are well known for their antiseptic and medicinal properties, use as antimicrobial, analgesics, sedatives and anti – inflammatory. The aim of this work was to determine the antimicrobial activity of 20 essential oils against positive Gram bacterias and negative Gram bacterias (Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853) and Candida type yeasts (C. albicans ATCC 10231, C. krusei ATCC 6258 and Candida parapsilosis ATCC 2209).
