抗生素耐药性的分子机制及抑菌策略

扫码查看
抗生素耐药性被认为是21世纪人类健康面临的最严重的全球性威胁之一,抗生素的过度使用加剧了细菌耐药性的产生,因此,需要进一步研究细菌耐药的机制,探索新型的耐药菌抑菌策略。本文从细菌耐药性的产生机制及耐药菌新型抑菌策略两方面进行概述,详细阐述了固有耐药性、获得耐药性和适应耐药性三种耐药性的分子机制,发现相较于具有强抗药性的固有耐药性及获得耐药性,新出现的适应耐药性具有群体效应及可逆性的特点。同时对新型抑菌化合物分子、噬菌体疗法、CRISPR-Cas系统疗法和反义疗法等新型抑菌策略进行了归纳,证明新型抗菌方法必须具备特异性和强响应性的特点。本综述旨在对细菌耐药性的发生机制进行总结,并为后续细菌耐药性的防治提供参考。
Molecular Mechanisms and Antibacterial Strategies of Antibiotic Resistance
Antibiotic resistance is considered one of the most serious global threats to human health in the 21st century.The overuse of antibiotics has aggravated the development of bacterial resistance.Therefore,it is necessary to further study the mechanisms of bacterial resistance and explore new types of resistance and bacteriostatic strategies.This article provides an overview of the mechanisms of bacterial resistance and new antibacterial strategies for drug-resistant bacteria.It elaborates on the molecular mechanisms of three types of resistance:inherent resistance,acquired resistance and adaptive resistance.It also discusses new antibacterial strategies such as new antibacterial compound molecules,phage therapy,CRISPR-Cas system therapy and antisense therapy.This review aims to summarize the mechanisms of bacterial resistance and provide a reference for subsequent prevention and treatment of bacterial resistance.
