Translational fidelity, the accuracy of protein synthesis, is crucial in all three domains of life. This article reviews how translational fidelity is affected by environmental stresses encountered by bacterial pathogens during host interactions, including oxidative stress, metabolic stresses, and antibiotics. The review discusses the types of translational errors and their impact on stress adaptation and fitness, as well as the roles of translational fidelity and underlying mechanisms in pathogen-host interactions. The studies covered in this review primarily focus on Salmonella enterica and Escherichia coli, but other bacterial pathogens are also discussed.
Translational fidelity refers to accuracy during protein synthesis and is maintained in all three domains of life. Translational errors occur at base levels during normal conditions and may rise due to mutations or stress conditions. In this article, we review our current understanding of how translational fidelity is perturbed by various environmental stresses that bacterial pathogens encounter during host interactions. We discuss how oxidative stress, metabolic stresses, and antibiotics affect various types of translational errors and the resulting effects on stress adaption and fitness. We also discuss the roles of translational fidelity during pathogen-host interactions and the underlying mechanisms. Many of the studies covered in this review will be based on work with Salmonella enterica and Escherichia coli, but other bacterial pathogens will also be discussed.
