Since its discovery in 1924 by J Clarke, Streptococcus mutans has been the focus of
rigorous research efforts due to its involvement in caries initiation and progression. Its ability …

Background Microbial cell-cell interactions in the oral flora are believed to play an integral
role in the development of dental plaque and ultimately, its pathogenicity. The effects of …

Streptococcus mutans is known to be resistant to bacitracin, a cyclic polypeptide antibiotic
produced by certain species of the genus Bacillus. This property is often exploited in the …

The Streptococcus mutans hdrRM operon encodes a novel two-gene regulatory system
induced by high cell density. Previous studies identified hdrM as the only known negative …

Glutamate contributes to the acid tolerance response (ATR) of many Gram-negative and
Gram-positive bacteria, but its role in the ATR of the oral bacterium Streptococcus mutans is …

Porphyromonas gingivalis is a late-colonizing bacterium of the subgingival dental plaque
