This paper identifies novel biofilm determinants in Streptococcus mutans using an arrayed transposon library and highlights genomic instability in the library that risks misattributing gene functions.

This paper characterizes EecP, a novel cell wall-anchored phosphodiesterase in E. faecalis that degrades extracellular c-di-AMP, showing its role in modulating host immune responses and infection outcomes.

This paper shows fructose activates a stress response in Streptococcus mutans similar to methylglyoxal and hydrogen peroxide, affecting gene expression and bacterial competitiveness.

This study shows that glycerol metabolism in oral commensal streptococci produces hydrogen peroxide, enhancing competition against the pathogen Streptococcus mutans.

This study analyzes CRISPR spacers in Streptococcus mutans genomes to assess their role in immunity and genomic diversification, finding minimal impact on genome expansion despite active spacer acquisition.
