New online! Revisiting the life cycle of temperate phages

Revisiting the life cycle of temperate phages

Nature Reviews Microbiology, Published online: 20 May 2026; doi:10.1038/s41579-026-01318-7The life cycle of temperate bacteriophages involves lytic or lysogenic cycles and has historically served as a model for studying genetic regulation. This Review provides an updated overview of these cycles and highlights their complexities, supporting a greater appreciation of the ecological roles of temperate phages.

Our work shows how different bacterial cell surface properties alter microbiogeography and social interactions! Fun collaboration with @digglelab.bsky.social

Recent work from the lab showing how presence of O-antigen deficient Pseudomonas variants change aggregate assembly and microbiogeography of infection journals.asm.org/doi/10.1128/...

Whole-tissue imaging reveals intrastrain diversity shapes the spatial organization of Pseudomonas aeruginosa in a murine infection model | mSphere

Intrastrain genetic and phenotypic diversity within Pseudomonas aeruginosa populations is common in chronic pulmonary infections. While this intrastrain heterogeneity is a hallmark of chronic infection, its consequences for the spatial organization of P. aeruginosa within the airways remain unclear. Here, we demonstrate that the loss of O-specific antigen in a subpopulation of P. aeruginosa significantly alters the spatial architecture of P. aeruginosa, without changing the total population size or composition. Using a combination of tissue clearing and hybridization chain reaction RNA-FISH in a murine lung infection model, we mapped the localization of genetically distinct P. aeruginosa variants in mixed populations in vivo. These findings reveal that genetic diversification within a strain can reshape the infection landscape at the micron scale, highlighting the overlooked role of intrastrain dynamics in shaping the microbiogeography of infections and influencing host-pathogen interactions.
