Abstract

In this issue, Bru et al. connect Pseudomonas aeruginosa PQS signaling secretion during stress response to swarming behavior (J.-L. Bru, B. Rawson, C. Trinh, K. Whiteson, et al., J Bacteriol 201:e00383-19, 2019, https://doi.org/10.1128/JB.00383-19). Phage-infected or antibiotic-treated bacterial cells secrete PQS to repel healthy, unexposed cells away from the source of the stress. Thus, the collective stress response mechanism driven by PQS signaling influences spatial organization and population dynamics in P. aeruginosa that may provide competitive advantages in certain niches.
