了解微生物对特定抗生素的耐药性如何影响对其他药物的敏感性是一项非常重要的挑战。通过结合实验室进化,基因组测序和功能分析,最近的工作绘制了抗生素之间的进化权衡图,并探索了潜在的分子机制。引人注目的是,引起细菌多药耐药性的突变同时增强了对许多其他无关药物的敏感性(间接敏感性)。在这里,我们探讨了这一新兴研究如何揭示耐药机制以及如何利用它来开发替代抗菌策略。
Understanding how evolution of microbial resistance towards a given antibiotic influences susceptibility to other drugs is a challenge of profound importance. By combining laboratory evolution, genome sequencing, and functional analyses, recent works have charted the map of evolutionary trade-offs between antibiotics and have explored the underlying molecular mechanisms. Strikingly, mutations that caused multidrug resistance in bacteria simultaneously enhanced sensitivity to many other unrelated drugs (collateral sensitivity). Here, we explore how this emerging research sheds new light on resistance mechanisms and the way it could be exploited for the development of alternative antimicrobial strategies.
