A humanized Galleria mellonella model reveals prophage-mediated breakdown of colonization resistance against Salmonella

Zachary M. Bailey, Lavisha Parab, Karina Krammer…·Carolin C. Wendling

This paper develops a humanized Galleria mellonella model to study prophage-mediated breakdown of colonization resistance against Salmonella, finding that prophages enhance pathogen success through metabolic changes in resident bacteria.
