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 …

Methods: Extensive literature survey was conducted using the scientific databases like

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 …

The finding that ingestion of antigens results in the selection induction of IgA antibodies in
external secretions suggests that antigen sensitizes Peyer's patch lymphoid cells, which …

The pac gene of the serotype c strain Streptococcus mutans MT8148 encodes a cell surface
protein antigen (PAc) of approximate 190 kilodaltons. The serotype c strain S. mutans GS-5 …

Generation of local and systemic immune responses by the oral administration of antigens is
frequently inefficient, requiring large quantities of immunogens and yielding only modest …

Streptococcus anginosus together with S. constellatus and S. intermedius constitute the
Streptococcus anginosus group (SAG), until recently considered to be benign commensals …

The human oral cavity is normally colonized by a wide range of microorganisms, including
bacteria, fungi, Archaea, viruses, and protozoa. Within the different oral microenvironments …

Streptococcus agalactiae (Group B Streptococcus, GBS) normally colonizes healthy adults
but can cause invasive disease, such as meningitis, in the newborn. To gain access to the …
