  • Avs proteins are bacterial anti-phage pattern recognition receptors evolutionarily related to eukaryotic NLRs. Here, Béchon et al show that a single bacterial Avs can recognize different phage proteins as a signature for infection, explaining the broad defensive range of Avs proteins.

  • Arbitrium, a peptide signal used by phages to communicate among themselves and control the lysis–lysogeny transition, is shown here to also regulate phage induction (the lysogeny–lysis transition). Arbitrium signalling represses DNA-damage-dependent phage induction, enabling prophages to sense the abundance of lysogens in the population so they can time the lytic transition for when uninfected hosts are available.

  • Some phages—viruses that infect bacteria—encode peptides that are secreted from infected cells and that, beyond a certain threshold, stimulate other viruses to switch from the lytic (killing the host cell) to lysogenic (dormant) phase.
