Molecular cloning and characterization of the spaB gene of Streptococcus sobrinus [PDF]

Journal of General Microbiology, 1990
A gene of Streptococcus sobrinus 6715 (serotype g) designated spaB and encoding a surface protein antigen was isolated from a cosmid gene bank. A 5.4 kb HindIII/AvaI DNA fragment containing the gene was inserted into plasmid pBR322 to yield plasmid pXI404. Analysis of plasmid-encoded gene products showed that the 5.4 kb fragment of pXI404 encoded a 195

Glycan-binding specificities of Streptococcus mutans and Streptococcus sobrinus lectin-like adhesins [PDF]

Clinical Oral Investigations, 2011
Since the adhesion of bacteria to the tooth surface is a prerequisite for dental plaque and subsequent caries development, a promising caries preventive strategy could be to block the lectin-glycan-mediated adherence of cariogenic bacteria. The aim of the study was to evaluate potential differences in glycan-binding specificities of two Streptococcus ...

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

Periodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Effect of polyclonal and monoclonal antibodies on surface properties of Streptococcus sobrinus [PDF]

Infection and Immunity, 1995
In this study, the effect of antibody adsorption on physicochemical properties of Streptococcus sobrinus was studied. Bacteria were preincubated with polyclonal antibodies or with OMVU10, a monoclonal antibody (MAb) reactive with S. sobrinus. The zeta potentials and the hydrophobicity as determined by microbial adhesion to hydrocarbons were measured in
