“…Pattern formation is ubiquitous in nature, arising in both non-living [87, 90–98] and living systems [87, 93, 94, 96, 97, 99–103]. Indeed, systems as diverse as proteins, amoeba, and even animal skin exhibit patterns that are remarkably similar to those revealed by our work [36–38, 90, 91, 95, 102, 104– 117], but which arise from a Turing-like instability due to differential diffusivity between two different species [61].…”

The interactions between bacteria and phages---viruses that infect bacteria---play critical roles in agriculture, ecology, and medicine; however, how these interactions influence the spatial organization of both bacteria and phages remain largely unexplored. Here, we address this gap in knowledge by developing a theoretical model of motile, proliferating bacteria that aggregate via motility-induced phase separation (MIPS) and encounter phage that infect and lyse the cells. We find that the non-reciprocal predator-prey interactions between phage and bacteria strongly alter spatial organization, in some cases giving rise to a rich array of finite-scale stationary and dynamic patterns in which bacteria and phage coexist. We establish principles describing the onset and characteristics of these diverse behaviors, thereby helping to provide a biophysical basis for understanding pattern formation in bacteria-phage systems, as well as in a broader range of active and living systems with similar predator-prey or other non-reciprocal interactions.
