抗生素耐受性(细菌在杀菌抗生素存在下长时间存活的能力)是导致抗生素治疗失败的一个尚未得到充分研究的因素。在此,我回顾了细胞壁活性(CWA)抗生素耐受性的表现、机制和临床相关性,细胞壁活性抗生素是临床使用最前沿的最重要的抗生素类别之一。我讨论了耐受性的定义和耐受性检测的测定,全面讨论了 β-内酰胺和其他 CWA 抗生素的作用机制,然后概述了细胞如何减轻 CWA 抗生素诱导的细胞损伤的潜在致命影响,从而变得耐受。最后,我讨论了 CWA 抗生素耐受性在临床抗生素治疗失败中的作用的证据。在此,我回顾了细胞壁活性(CWA)抗生素耐受性的表现、机制和临床相关性,细胞壁活性抗生素是临床使用最前沿的最重要的抗生素类别之一。我讨论了耐受性的定义和耐受性检测的测定,全面讨论了 β-内酰胺和其他 CWA 抗生素的作用机制,然后概述了细胞如何减轻 CWA 抗生素诱导的细胞损伤的潜在致命影响,从而变得耐受。最后,我讨论了 CWA 抗生素耐受性在临床抗生素治疗失败中的作用的证据。
Antibiotic tolerance—the ability of bacteria to survive for an extended time in the presence of bactericidal antibiotics—is an understudied contributor to antibiotic treatment failure. Herein, I review the manifestations, mechanisms, and clinical relevance of tolerance to cell wall–active (CWA) antibiotics, one of the most important groups of antibiotics at the forefront of clinical use. I discuss definitions of tolerance and assays for tolerance detection, comprehensively discuss the mechanism of action of β‐lactams and other CWA antibiotics, and then provide an overview of how cells mitigate the potentially lethal effects of CWA antibiotic–induced cell damage to become tolerant. Lastly, I discuss evidence for a role of CWA antibiotic tolerance in clinical antibiotic treatment failure.
