Prevalence of Csh-like fibrillar surface proteins among mitis group oral streptococci.
The prevalence of Csh-like fibrillar surface proteins among oral streptococci was investigated by ELISA and by immunoelectron microscopy using antiserum raised to recombinant fragments of CshA of Streptococcus gordonii DL1. The majority of S. gordonii, Streptococcus sanguis and Streptococcus oralis strains tested elaborated short (ca. 50-80 nm long) surface fibrils and reacted with antiserum to...
متن کاملOral Streptococci Biofilm Formation on Different Implant Surface Topographies
The establishment of the subgingival microbiota is dependent on successive colonization of the implant surface by bacterial species. Different implant surface topographies could influence the bacterial adsorption and therefore jeopardize the implant survival. This study evaluated the biofilm formation capacity of five oral streptococci species on two titanium surface topographies. In vitro biof...
متن کاملStress Responses of Oral Streptococci
To persist in the oral cavity, bacteria must be able to tolerate rapid and substantial environmental fluctuations, particularly in pH and nutrient source and availability. Various species of Streptococcus, one of the most abundant genera in the mouth, are associated with oral health, as well as with dental caries. Cariogenic streptococci depend on a biofilm lifestyle for survival and persistenc...
متن کاملHydrogen Peroxide Produced by Oral Streptococci Induces Macrophage Cell Death
Hydrogen peroxide (H2O2) produced by members of the mitis group of oral streptococci plays important roles in microbial communities such as oral biofilms. Although the cytotoxicity of H2O2 has been widely recognized, the effects of H2O2 produced by oral streptococci on host defense systems remain unknown. In the present study, we investigated the effect of H2O2 produced by Streptococcus oralis ...
متن کاملEvaluation of the antimicrobial effects of extract of Zataria multiflora against oral Streptococci
Dental caries is the most common chronic disease which involve the civilized humankind and is designated as the “disease of the civilization”. Oral Streptococci such as S. sanguis, S. salivarius and S. mutans have a very important role to play in the process of plaque formation. In order to inhibit and control caries process, the growth of such Streptococci must be reined. The purpose of this s...
