Impact of the RaS-RiPP tryglysin and culturing conditions on ex-vivo oral microbiomes.

Britta E. Rued, Achal Dhariwal, Brett C. Covington…·Fernanda C. Petersen

This study investigates how Tryglysin A, a RaS-RiPP produced by Streptococcus, affects ex-vivo oral microbiomes and identifies key culturing factors for these systems.

HAMLET, a human milk protein-lipid complex, modulates amoxicillin-induced changes in an ex vivo biofilm model of the oral microbiome

N. K. Brar, Achal Dhariwal, Sudhanshu Shekhar…·Fernanda C. Petersen

This study shows that HAMLET combined with amoxicillin reduces oral biofilm viability and increases Lactobacillus crispatus, suggesting synergistic antimicrobial effects in a polymicrobial model.
