Host happy hour: Phage cocktail targets IBD-associated microbes.

Bacteriophage therapy is a promising strategy to treat bacterial infections and sculpt the microbiome. In a recent Cell paper, Federici et al. (2022) demonstrate that a Klebsiella pneumoniae phage cocktail can specifically remove pathobionts from the mouse gut. Safety and persistence of therapeutic phages were shown in a Phase 1 trial.
