The localization and accessibility of the group B streptococcus (GBS) surface immunogenic
protein (Sip) at the surface of intact GBS cells were studied by flow cytometric assay and …

The M protein is one of the most important virulence factors of group A streptococci
(Streptococcus pyogenes) and may play an important role in the first steps of streptococcal …

Streptococcus gordonii, a normal inhabitant of the human oral cavity, is a potential live
vaccine vehicle. Several pathogen-associated molecular patterns from S. gordonii that are …

Background Gram-negative bacteria have developed a limited repertoire of solutions for
secreting proteins from the cytoplasmic compartment to the exterior of the cell. Amongst the …

Group A streptococci were recently shown to be capable of invading human epithelial cell
monolayers. Cell invasion might be an important virulence trait of streptococci that enable …

The ability of a serotype M1 strain of Streptococcus pyogenes to efficiently invade A549
human lung epithelial cells was previously shown to be dependent on bacterial exposure to …

Streptococcal inhibitor of complement (Sic) is a secreted protein made predominantly by
serotype M1 Group A Streptococcus (GAS), which contributes to persistence in the …

Adherence to and invasion of epithelial cells represent important pathogenic mechanisms of
Streptococcus pyogenes. A fibronectin‐binding surface protein of S. pyogenes, SfbI protein …

The type III secretion system (T3SS) is highly conserved in many Gram-negative pathogenic
bacteria and functions as an injector of bacterial proteins (effectors) into host cells. T3SSs …

We have demonstrated previously by Western blotting that in naturally sensitized humans,
the serum or salivary antibody response to Streptococcus mutans was directed …
