The cell wall envelope of gram-positive bacteria is a macromolecular, exoskeletal organelle
that is assembled and turned over at designated sites. The cell wall also functions as a …

Human oral bacteria interact with their environment by attaching to surfaces and
establishing mixed-species communities. As each bacterial cell attaches, it forms a new …

Streptococci readily colonize mucosal tissues in the nasopharynx; the respiratory,
gastrointestinal, and genitourinary tracts; and the skin. Each ecological niche presents a …

Streptococcus bovis (S. bovis) bacteria are associated with colorectal cancer and adenoma.
S. bovis is currently named S. gallolyticus. 25 to 80% of patients with S. bovis/gallolyticus …

Saliva is thought to have a significant impact on the colonization of microorganisms in the
oral cavity. Salivary components may participate in this process by one of four general …

Streptococcus mutans antigen I/II (AgI/II) protein was one of the first cell wall‐anchored
adhesins identified in Gram‐positive bacteria. It mediates attachment of S. mutans to tooth …

A gene from Streptococcus pneumoniae (nanA), with features entirely consistent with a
neuraminidase gene, has been sequenced. High levels of neuraminidase activity were …

The ability to adhere to salivary agglutinin-coated hydroxyapatite beads and to aggregate in
the presence of fluid-phase salivary agglutinin was tested by using 25 isolates of mutants …

Streptococci have a vast repertoire of adherence properties which include binding to human
tissue components, epithelial cells and to other bacterial cells. These interactions are …

Dental caries is one of the most common infectious diseases. Of the oral bacteria, mutans
streptococci, such as Streptococcus mutans and S. sobrinus, are considered to be causative …
