The paper investigates how prophage costs and competitive benefits shape bacterial evolution in polymicrobial environments, finding environment-dependent adaptive strategies and trade-offs.

The paper shows capsule exchange in Klebsiella pneumoniae has minimal fitness costs and preserves virulence traits across genetic backgrounds, suggesting plug-and-play dynamics in capsule loci.

This study analyzes Klebsiella strains from ICU patients to show that within-host genetic changes, not virulence traits, drive progression from gut colonization to bloodstream infections.
