The paper shows that E. faecalis evolves to metabolize fructoselysine, reducing S. Typhimurium colonization by limiting a key nutrient.

The paper shows that gut bacteria like Klebsiella oxytoca, under anoxic conditions, suppress Acinetobacter baumannii through metabolites from specific carbohydrates like maltose.

The paper investigates how dietary components and Enterobacteriaceae influence competition between Prevotellaceae and Bacteroidaceae in the gut microbiota, finding that Enterobacteriaceae enhance Prevotellaceae dominance under specific conditions.

This study shows that inhibiting polysaccharide breakdown in Bacteroides thetaiotaomicron reduces cross-feeding and growth of Salmonella Typhimurium in mice.

The paper adapts Cas9-based gene editing to study species-specific competition mechanisms in Klebsiella species.
