Aims: To investigate the structural organization and dynamics of exopolysaccharides (EPS)
matrix and microcolonies formation by Streptococcus mutans during the biofilm development …

Horizontal gene transfer through natural DNA transformation is an important evolutionary
mechanism among bacteria. Transformation requires that the bacteria are physiologically …

A single transposon insertion upstream to the open-reading-frame identified as the
streptococcal acid glycoprotein (sagp) gene rendered a Tn916 isolate of Streptococcus …

ABSTRACT Mature Fap1, a 200-kDa fimbria-associated adhesin, is required for fimbrial
biogenesis and biofilm formation in Streptococcus parasanguis. Fap1-like proteins are found …

Bacteria exposed to transient host environments can elicit adaptive responses by triggering
the differential expression of genes via two-component signal transduction systems. This …

Background/aims: Streptococcus parasanguinis is a primary colonizer of the tooth surface.
Its adhesion is mediated by the long fimbriae, which are composed of multiple subunits of a …

Streptococcus mutans is a major cariogenic bacterium. It has adapted to the biofilm lifestyle,
which is essential for pathogenesis of dental caries. We aimed to identify small molecules …

Streptococcus gordonii is a pioneer colonizer of the teeth, contributing to the initiation of the
oral biofilm called dental plaque. To identify genes that may be important in biofilm …

The luxS gene, present in many bacterial genera, encodes the autoinducer 2 (AI-2)
synthase. AI-2 has been implicated in bacterial signaling, and this study investigated its role …

Streptococcus mutans is a main organism of tooth infections including tooth decay and
periodontitis. The aim of this study was to assess the influence of sucrose and starch on …
