Here is what the page “Migration-Mediated Coexistence: How Bacteria and Phages Survive Together, New Study Reveal” contains. Bacteria and the viruses that infect them, called phages, are found together in diverse environments—from soils and oceans to the human body. For decades, scientists believed their coexistence was driven by an evolutionary arms race, with hosts and parasites constantly adapting to one another. But new research from the University of Maryland and the University of Exeter challenges that view, revealing a different mechanism: migration.
The study shows that when bacteria and phages move between different patches of habitat, they can coexist without the need for rapid coevolution. This migration-mediated coexistence allows both populations to persist, even when local conditions would otherwise favor one over the other. The findings have broad implications for understanding microbial ecology, including how phage therapy might be optimized to treat bacterial infections without triggering resistance. The full version stays on the original page, which this listing opens directly.
