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.

了解细胞壁活性抗生素的耐受性



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。
