  • The recalcitrance of many infections to antibiotic treatment may be due to the presence of ‘persisters’, or non-growing, antibiotic-tolerant bacteria. Here, the authors study the structures and functions of aminoacyl-tRNA acetyltransferase toxins, and their roles in persister formation in Salmonella.

  • Many bacteria can infect and persist inside their hosts for long periods of time. In this Review, Fisher, Gollan and Helaine discuss recent developments in our understanding of bacterial persisters and their potential implications for the treatment of persistent infections.

  • Transcription of toxin–antitoxin modules is regulated by conditional cooperativity, where the toxin enables or disrupts antitoxin-driven repression. Here, the authors solve the structural basis for the conditional cooperativity of Salmonella TacAT3.

  • Three Neisseria meningitidis RNA thermosensors important for resistance against complement-mediated immune killing are identified, located in the 5′ untranslated regions of genes necessary for capsule biosynthesis, expression of factor H binding protein and sialyation of lipolysaccharide; increased temperature may act as a warning signal for the bacterium, prompting it to enhance mechanisms of immune evasion.
