Introduction: Infectious disease is still a common cause of illness and death in developing countries, such as Indonesia. One of the bacteria that causes infectious disease is Streptococcus pyogenes. Cacao fruit is a large commodity in Indonesia and has benefit for human. Cacao’s rind is known to contain several active compounds such as flavonoid and alkaloid that have antibacterial effect that can inhibit Streptococcus pyogenes growth. This research aims to evaluate the Minimum Bactericidal Concentration (MBC) of cacao rind ethanol extract in inhibiting Streptococcus pyogenes growth in vitro.  Methods: This research was a laboratory experimental study, testing antibacterial activity of cacao’s rind ethanol extract in inhibiting growth of bacteria Streptococcus pyogenes using dilution method in vitro to know the MIC and MBC result. Sample of bacteria Streptococcus pyogenes was obtained from Balai Besar Laboratorium, Surabaya. Sample of cacao’s rind ethanol extract was extracted at Balai Materia Medica, Batu.  Results: At the beginning this experiment was done to find the MIC and MBC of cacao’s rind ethanol extract against the growth of bacteria Streptococcus pyogenes, but the researcher can only find the MBC result, because the extract color is very dark, so the turbidity result of tubes P1 – P7 cannot be compared to control tube. From the results, the researcher draws a table showing how turbid and dark those tubes are. More (+) signs means more turbid or darker the tube is. From dilution test, the MBC of cacao’s rind ethanol extract against the growth of bacteria Streptococcus pyogenes is 12.5%. Conclusion: Cacao’s rind (Theobroma cacao L.) was quite effective in increasing the growth of bacteria Streptococcus pyogenes in vitro, the Minimum Bactericidal Concentration (MBC) is 12.5%

ABSTRACT Imbalances within the dental biofilm trigger dental caries, currently considered a dysbiosis and the most prevalent noncommunicable disease. There is still a gap in knowledge about the dynamics of enamel colonization by bacteria from the dental biofilm in caries. The aim, therefore, was to test whether the sequence of enamel colonization by a typically commensal and a cariogenic species modifies biofilm’s cariogenicity. Dual-species biofilms of Streptococcus mutans and Streptococcus sanguinis on saliva-coated enamel slabs were inoculated in different sequences: S. mutans followed by S. sanguinis (Sm-Ss), S. sanguinis followed by S. mutans (Ss-Sm), S. mutans and S. sanguinis inoculated at the same time (Sm=Ss), and the single-species controls S. mutans followed by S. mutans (Sm-Sm) and S. sanguinis followed by S. sanguinis (Ss-Ss). Biofilms were exposed to 10% sucrose 3 times per day for 5 days, and the slabs/biofilms were retrieved to assess demineralization, viable cells, biomass, proteins, polysaccharides, and H2O2 production. Compared with Sm-Sm, primary inoculation with S. sanguinis reduced demineralization (P < 0.05). Both Ss-Sm and Sm=Ss sequences showed reduction in biomass, protein, and polysaccharide content (P < 0.05). The highest S. sanguinis viable count and H2O2 production level and the lowest acidogenicity were observed when S. sanguinis colonized enamel before S. mutans (P < 0.05). Initial enamel adherence with commensal biofilms seems to induce more intense competition against more typically cariogenic species, reducing cariogenicity. IMPORTANCE The concept of caries as an ecological disease implies the understanding of the intricate relationships among the populating microorganisms. Under frequent sugar exposure, some bacteria from the dental biofilm develop pathogenic traits that lead to imbalances (dysbiosis). Depending on which microorganism colonizes the dental surface first, different competition strategies may be developed. Studying the interactions in the entire dental biofilm is not an easy task. In this study, therefore, we modeled the interplay among these microorganisms using a caries-inducing species (S. mutans) and a health-associated species (S. sanguinis). Initial enamel adherence with S. sanguinis seems to induce more intense competition against typically caries-inducing species. Besides continuous exposure with sugars, early colonization of the enamel by highly cariogenic species like S. mutans appears to be needed to develop caries lesions as well. Promoting early colonization by health-associated bacteria such as S. sanguinis could help to maintain oral health, delaying dysbiosis.

The main objective of this study is to evaluate the antibacterial effect of antibacterial photodynamic therapy (aPDT) on Streptococcus mutans (S. mutans) biofilm model in vitro. The selection of photosensitizers is the key step for the efficacy of photodynamic therapy (PDT). However, no studies have been conducted in the oral field to compare the functional characteristics and application effects of PDT mediated by various photosensitizers. In this research, the antibacterial effect of Methylene blue (MB)/650[Formula: see text]nm laser and Hematoporphyrin monomethyl ether (HMME)/532[Formula: see text]nm laser on S. mutans biofilm was compared under different energy densities to provide experimental reference for the clinical application of the two PDT. The yield of lactic acid was analyzed by Colony forming unit (CFU) and spectrophotometry, and the complete biofilm activity was measured by Confocal Laser Scanning Microscopy (CLSM) to evaluate the bactericidal effect on each group. Based on the results of CFU, the bacterial colonies formed by 30.4[Formula: see text]J/cm2 532[Formula: see text]nm MB-aPDT group and 30.4[Formula: see text]J/cm2 532[Formula: see text]nm HMME-aPDT group were significantly less than those in other groups, and the bacterial colonies in HMME-aPDT group were less than those in HMME-aPDT group. Lactic acid production in all treatment groups except the photosensitizer group was statistically lower than that in the normal saline control group. The activity of bacterial plaque biofilm was significantly decreased in the two groups treated with 30.4[Formula: see text]J/cm2 aPDT. Therefore, aPDT suitable for energy measurement can kill S. mutans plaque biofilm, and MB-aPDT is better than HMME-aPDT.

ABSTRACTStreptococcus mutansis often cited as the main bacterial pathogen in dental caries, particularly in early-childhood caries (ECC).S. mutansmay not act alone;Candida albicanscells are frequently detected along with heavy infection byS. mutansin plaque biofilms from ECC-affected children. It remains to be elucidated whether this association is involved in the enhancement of biofilm virulence. We showed that the ability of these organisms together to form biofilms is enhancedin vitroandin vivo. The presence ofC. albicansaugments the production of exopolysaccharides (EPS), such that cospecies biofilms accrue more biomass and harbor more viableS. mutanscells than single-species biofilms. The resulting 3-dimensional biofilm architecture displays sizeableS. mutansmicrocolonies surrounded by fungal cells, which are enmeshed in a dense EPS-rich matrix. Using a rodent model, we explored the implications of this cross-kingdom interaction for the pathogenesis of dental caries. Coinfected animals displayed higher levels of infection and microbial carriage within plaque biofilms than animals infected with either species alone. Furthermore, coinfection synergistically enhanced biofilm virulence, leading to aggressive onset of the disease with rampant carious lesions. Ourin vitrodata also revealed that glucosyltransferase-derived EPS is a key mediator of cospecies biofilm development and that coexistence withC. albicansinduces the expression of virulence genes inS. mutans(e.g.,gtfB,fabM). We also found thatCandida-derived β1,3-glucans contribute to the EPS matrix structure, while fungal mannan and β-glucan provide sites for GtfB binding and activity. Altogether, we demonstrate a novel mutualistic bacterium-fungus relationship that occurs at a clinically relevant site to amplify the severity of a ubiquitous infectious disease.

This study evaluated the combined inhibitory effects of a Curcuma xanthorrhiza extract (CXE) and Xylitol on S. mutans and A. viscosus in vitro. Three series of experiments on S. mutans and A. viscosus were carried out. In the first series, the Minimum inhibitory concentrations (MICs) of CXE, Xylitol, and CXE mixed with Xylitol (CXE+Xylitol) against S. mutans and A. viscosus were determined. Second, the antibacterial effect and the rapid effectiveness of CXE, Xylitol, and CXE+Xylitol against those bacteria was evaluated as contacting for 1, 2, 5, and 10 minutes. Finally, The saccharolytic capability of S. mutans was examined using bovine teeth that had been pretreated with CXE (1%), Xylitol (1%), CXE+Xylitol (1%), chlorhexidine (1%) and distilled water, and rinsed with distilled water. The pretreated bovine teeth were layered with soft agar containing sucrose (5%), S. mutans and phenol red, as a pH indicator, and incubated. The MICs of CXE were 5 ppm on both bacterial species. Xylitol did not inhibit either species. The MICs of CXE+Xylitol were 10 and 5 ppm against S. mutans, A. viscosus, respectively. According to the rapid effectiveness, CXE completely inhibited the growth of bacteria but Xylitol did not. CXE+Xylitol could completely inhibit the growth of bacteria. An evaluation of the saccharolytic capability of S. mutans on bovine teeth revealed that distilled water and Xylitol could not inhibit bacterial fermentation. However, the bovine teeth containing CXE, CXE+Xylitol and chlorhexidine inhibited the fermentation of bacteria. These results show that CXE and CXE+Xylitol have a strong antibacterial effect on S. mutans and A. viscosus in vitro.
