Antimicrobial Mechanisms and Mode of Actions of Nanoemulsion Against Drug-Resistant ESKAPE Pathogens

Abstract

An enhancement of antibiotic resistance in bacteria is associated with increased morbidity, mortality, and health infrastructure and hospital care charges. The Infectious Diseases Society of America (IDSA) has highlighted a section of antibiotic resistant bacteria termed as ESKAPE pathogens. These pathogens are proficient in ‘escaping' the biocidal effect of antibiotics and mutually representing new paradigms in transmission of diseases, pathogenesis, and resistance in their genetic materials. Essential oil-based nanoemulsions (NEs) have great interest towards the “natural” therapies as potential antimicrobial agents. Thermodynamic properties and kinetically stable potential of biphasic system of nanoemulsion enable them to be used as an effective nano-carrier with controlled release at the targeted point. This chapter describes the mechanisms of ESKAPE pathogens and the mode of the mechanisms of antimicrobial action of nanoemulsions for the treatment of MDR human pathogens.
