This paper identifies a small molecule regulated by a TetR family regulator that controls the GA3 T6SS and immunity genes in Bacteroides fragilis, enabling coordinated antagonism and defense.

The paper characterizes a large collection of Bacteroidales isolates from the human gut, revealing genomic and metabolomic diversity and horizontal gene transfer across species.

The paper characterizes six gut-derived nisin-like lantibiotics, evaluates their antimicrobial activity against pathogens and commensals, and identifies key residues affecting their activity.
