所有微生物都暴露在抑制生长的周期性压力下。许多细菌和真菌通过进入一种耐寒的、非复制的状态来经受住这些时期,这种状态通常被称为静止或休眠。当这种情况发生在感染期间时,产生的缓慢生长的病原体能够耐受免疫侮辱和长期接触抗生素。虽然在自由生活环境中遇到的压力可能不同于寄主免疫施加的压力,但这些限制生长的条件施加了共同的压力,许多相应的微生物反应似乎是普遍的。在这篇综述中,我们讨论了这些生长受限状态的共同特征,这为治疗结核病等慢性感染提出了新的方法。
All microorganisms are exposed to periodic stresses that inhibit growth. Many bacteria and fungi weather these periods by entering a hardy, non-replicating state, often termed quiescence or dormancy. When this occurs during an infection, the resulting slowly-growing pathogen is able to tolerate both immune insults and prolonged antibiotic exposure. While the stresses encountered in a free-living environment may differ from those imposed by host immunity, these growth-limiting conditions impose common pressures and many of the corresponding microbial responses appear to be universal. In this review, we discuss the common features of these growth-limited states, which suggest new approaches for treating chronic infections such as tuberculosis.
