Antimicrobial effects of herbal extracts on Streptococcus mutans and normal oral streptococci. Streptococcus mutans is associated with dental caries. A cariogenic biofilm, in particular, has been studied extensively for its role in the formation of dental caries.
Herbal extracts such as Cudrania tricuspidata, Sophora flavescens, Ginkgo biloba, and Betula Schmidtii have been used as a folk remedy for treating diseases. The purpose of this study was to evaluate and compare the antibacterial activity of herbal extracts against normal oral streptococciplanktonic and biofilm of S. Streptococcus gordonii, Streptococcus oralis, Streptococcus salivarius, Streptococcus sanguinis, and S.
The biofilm antiestreptolisijas treated with the herbal elevavas in various concentrations and inoculated on Mitis-Salivarius bacitracin agar plate for enumeration of viable S. The normal oral streptococci exhibited a weak susceptibility in comparison to S. In conclusion, the extract of S. Collagen-binding proteins of Streptococcus mutans and related streptococci. The ability of Streptococcus mutans to interact with collagen through the expression of collagen-binding anntiestreptolisinas CBPs bestows this oral pathogen with an alternative to the sucrose-dependent mechanism of colonization classically attributed to caries development.
Based on the abundance and distribution of collagen throughout the human body, stringent adherence to this molecule grants S. However, robust antiestreptolisinws binding is not achieved by all strains of S. These observations merit careful dissection of the contribution from these different CBPs towards tissue colonization and virulence.
In this review, we will discuss the current understanding of mechanisms used by S. Summary The ability of Streptococcus mutans to interact with collagen through the expression antiestrpetolisinas collagen-binding proteins CBPs bestows this oral pathogen with an alternative to the sucrose-dependent mechanism of colonization classically attributed to caries development.
Surface proteins, such as SpaP, WapA, Cnm and Cbm, have been shown to bind collagen in vitro, and it has been suggested that these molecules play a role in colonization of oral and extra- oral tissues. In this review, we will discuss the current understanding of mechanisms utilized by S. Bacteriostatic effect of simvastatin on selected oral streptococci in vitro. Directory of Open Access Journals Sweden. Full Text Available Context and Objective: Simvastatin is a widely used cholesterol-lowering drug, which has been found to have a number of pleiotropic effects.
The aim of this study was to evaluate the antimicrobial effectiveness of simvastatin against selected oral streptococci as determined by the minimum inhibitory concentration MIC. Streptococcus mutans, Streptococcus sanguis, Streptococcus anginosus, and Streptococcus salivarius were the test microorganisms.
The serial dilution method was used to determine the MIC of simvastatin against these organisms. The MIC was defined as the lowest concentration of simvastatin that completely inhibited growth of the test organisms. The data indicate that simvastatin inhibits the growth of the test organisms, with MIC’s ranging from 7. Simvastatin has MIC’s against the selected bacteria that compare favorably with reported values for topical agents such as essential oil, chlorhexidine gluconate, and triclosan.
The levels of simvastatin required to inhibit bacterial growth of oral bacteria exceed the reported levels of the drug found in plasma or crevicular fluid of patients who are treated with this cholesterol-lowering drug. However, clinical studies are warranted to investigate the potential use of simvastatin as a novel antiplaque agent that could be used in local drug delivery to the oral cavity of those patients who are prescribed this cholesterol-lowering drug.
Capsular typing of Streptococcus agalactiae Lancefield group B streptococci from fish using multiplex PCR and serotyping. This study evaluated a published multiplex PCR capsul Preventive effects of a phospholipid polymer coating on PMMA on biofilm formation by oral streptococci. The regulation of biofilm formation on dental materials such as denture bases is key to oral health.
Recently, a biocompatible phospholipid polymer, poly 2-methacryloyloxyethyl phosphorylcholine-co-n-butyl methacrylate PMB coating, was reported to inhibit sucrose-dependent biofilm formation by Streptococcus mutans, a cariogenic bacterium, on the surface of poly methyl methacrylate PMMA denture bases. Other, more predominant oral streptococci must play an indispensable role in sucrose-independent biofilm formation. In the present study, the effect of PMB coating on PMMA was evaluated using various oral streptococci that are known to be initial colonizers during biofilm formation on tooth surfaces.
Streptococci other than S. On the other hand, all seven species of oral streptococci exhibited distinctly reduced glucose-dependent soft biofilm retention on PMB-coated PMMA. PCR detection and identification of oral streptococci in saliva samples using gtf genes.

Oral streptococci are major constituents of dental plaque, and their prevalence is implicated in various pathologies. Therefore, accurate identification of oral streptococci would be valuable for studies of cariogenic plaque and for diagnostic use in infective endocarditis. Many oral streptococci possess glucosyltransferase enzymes that synthesize glucan, which is an obligate component of dental plaque. We established a rapid and precise method to identify oral streptococci by Elrvadas using the species-specific region from the glucosyltransferase gene.
With the species-specific primers, Streptococcus mutans, S. Further, we developed a simple method to extract the bacterial DNA from saliva. Their distribution was in accord with results of conventional biochemical tests. The novel species Streptococcus tigurinus and its association with oral antiestreptilisinas. Streptococcus tigurinus is a novel species of viridans streptococcishown to cause severe invasive infections such as infective endocarditis, spondylodiscitis and meningitis.
The presence of S. This review addresses the available scientific knowledge on S.
While natiestreptolisinas is as yet no strong evidence on the involvement of S. FACS analyses were used to determine the percentages of various hu-T cell types, as well as intracellular cytokine production of interleukin-4 and interferon-gamma.
Serum IgG and IgM antibody levels in response to the streptococci were also determined by enzyme-linked immunosorbent assay. These results may contribute to a better understanding of human lymphocyte interactions to biofilm bacteria, along with their impact on dental and mucosal inflammatory diseases, as well as endocarditis.
Strain-related acid production by oral streptococci. Acid production, in particular at low pH, is thought to be an important ecological determinant in dental caries. The aim of the present study was to determine the acid producing capability at different pH levels of 47 streptococcal strains, representing 9 species, isolated from human dental plaque The bacteria were grown until mid log-phase under anaerobic conditions and acid production was measured in a pH-stat system at pH 7.
At all pH values, the mean velocity of acid antiestrepfolisinas V ap by Streptococcus mutans and S. However, the V ap of some strains of S. Confocal Raman Microspectroscopy of Oral Streptococci. Raman spectroscopy has been used in a variety of antiestreptolisinnas throughout the field of biomedical optics. It has the ability to acquire chemically-specific information in a non-invasive antiestreptollisinas, without the need for exogenous markers.
This makes it useful in the identification of bacterial species, as well as in antkestreptolisinas study of tissues and other cells. In this work, a species identification model has been created in order to discriminate between the oral bacterial species Streptococcus sanguinis and Streptococcus mutans.
These are two of the most prevalent species within the human mouth and their relative concentrations can be an indicator of a patient’s oral health and risk of tooth decay. They are predominantly found within plaque on the tooth’s surface. To study a simplified model for dental plaque, we have examined S.
Raman spectroscopy has been implemented here through a confocal microscope. The optical system has been equipped with computationally controlled stages to allow for automated scanning, including autofocusing to probe a consistent depth within a sample. A spectrum has been acquired from each position within a scan and sent for spectral preprocessing before being submitted for species identification. This preprocessing includes an algorithm that has been developed to remove fluorescence features from known contaminants within the confocal volume, to include signal from a fluorescent substrate.
Species classification has been accomplished using a principal component score-fed logistic regression model constructed from a variety of biofilm samples that have been transferred and allowed to dry, as might occur with the study of plaque samples. This binary classification model has been validated on other samples with identical preparations.
The model has also been transferred to determine the species of hydrated biofilms studied in situ. Artificially mixed biofilms have been examined to test the spatial. Alkali production associated with malolactic fermentation by oral streptococci and protection against acid, oxidative, or starvation damage. Alkali production by oral streptococci is considered important for dental plaque ecology and caries moderation. Recently, malolactic fermentation MLF was identified as a major system for alkali production by oral streptococciincluding Streptococcus mutans.
Our major objectives in the work described in this paper were to further define the physiology and genetics of MLF of oral streptococci and its roles in protection against metabolic stress damage. Mutants for mleR the contiguous regulator gene had intermediate capacities for MLF. Loss of capacity to catalyze MLF resulted in loss of capacity for protection against lethal acidification. MLF was also found to be protective against oxidative and starvation damage.
The capacity of S. MLF acted additively with the arginine deiminase system for alkali production by Streptococcus sanguinis, but not with urease of Streptococcus salivarius. Malolactic fermentation is clearly a major process for alkali generation by oral streptococci and for protection against environmental stresses. Sheng, Jiangyun; Baldeck, Jeremiah D.
