Abstract

Antimicrobial resistance has been reported since the discovery of antibiotics; the microorganisms which have been exposed to antibiotics are continuously and rapidly evolving to overcome the effect of antimicrobial agents. This has made antimicrobial resistance a major public health issue. In order to overcome antimicrobial resistance, various alternatives are being explored; this includes the utilization of plant essential oils, which are mixtures of secondary metabolites produced by plants that have antimicrobial activity. Essential oils have proven to be effective against various pathogens such as, Klebsiella pneumoniae, Campylobacter jejuni, Staphylococcus aureus and others.

This chapter aims to briefly discuss resistance mechanisms employed by microorganisms and alternative methods used to overcome antimicrobial resistance. Then, the chemistry of essential oils and the effects these essential oils have on the genomes and proteomes of the treated microorganisms has also been reviewed. These essential oils should be further explored in the future to examine their toxicity and side effects through in vitro and clinical studies.
