A host-directed virulence factor of Clostridium perfringens is modulated by gut commensal strains

The paper investigates how gut commensal strains modulate the growth and virulence of Clostridium perfringens through substrate competition and protein level changes.

Community composition drives metabolic competition and Staphylococcus aureus colonization resistance in synthetic nasal communities

The paper constructs synthetic nasal communities to study how community composition influences metabolic competition and S. aureus colonization resistance.

Deciphering the metabolic details of L-lysine toxicity in cyanobacteria

This study investigates the metabolic and physiological effects of L-lysine on Synechocystis sp. PCC 6803, identifying key genes involved in Lys resistance and metabolic disruption.

Native metabolomics identifies pteridines as CutA ligands and modulators of copper binding

The paper identifies pteridines, including lumazine dehydroxyxanthopterin B2, as natural ligands of CutA that modulate copper binding and redox homeostasis in E. coli and Synechococcus elongatus.

Synergy between Enterobacteriaceae and dietary components shapes the competition between the dominant anaerobes of the human gut

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.

Tyrosine availability shapes Staphylococcus aureus nasal colonization and interactions with commensal communities

The paper shows that tyrosine availability influences Staphylococcus aureus nasal colonization and its interactions with commensal bacteria.
