The dynamics of phage predation on a microcolony

The paper experimentally quantifies phage predation on E. coli microcolonies and uses a model to show that T4 phage can penetrate deep enough to threaten colony survival despite shielding.

Emergence of networks of shared restriction-modification systems in phage-bacteria ecosystems

The paper analyzes RM system sharing in bacterial strains and models phage-bacteria dynamics to identify non-random network structures and two bacterial strategies.

On phage adsorption to bacterial chains

The paper investigates how bacterial spatial arrangements affect phage adsorption rates and shows that clustered structures significantly reduce adsorption and increase superinfection rates.

Defense versus growth in a hostile world - Lessons from phage and bacteria

The paper models bacterial-phage interactions showing that diversity is determined by a trade-off between growth rate and defense mechanisms, not just growth rate alone.

Sustainability of spatially distributed bacteria-phage systems

The paper models spatially distributed bacteria-phage systems to show that spatial separation and colony growth protect bacteria from phage-driven extinction.

A Growing Microcolony can Survive and Support Persistent Propagation of Virulent Phages

The paper shows that larger bacterial colonies can survive virulent phages by outgrowing surface infections, with a critical size threshold identified through mathematical modeling.
