Streptococcus mutanspredominantly creates an acidic environment in an oral cavity. This results in dental demineralization and carious lesions. The probiotics are beneficial microorganisms that modulate the bacterial balance in the digestive system. Prebiotics are defined as nondigestible oligosaccharides that are utilized for the selective stimulation of the beneficial microorganisms. The objective of this study was to evaluate the efficacy of the prebiotics, galactooligosaccharides (GOS) and fructooligosaccharides (FOS), for enhancing the probioticLactobacillus acidophilusATCC 4356, for inhibitingStreptococcus mutans(A32-2) for the prevention of dental caries. The growth rate of theS. mutanssignificantly decreased when cocultured withL. acidophilusin the GOS-supplemented medium at 3%, 4%, and 5%. In the FOS-supplemented medium, the growth rate ofS. mutanssignificantly decreased in all concentrations when cocultured withL. acidophilus. There was no significant difference in the growth rate ofL. acidophilusin all concentrations of either GOS or FOS. It can be concluded that the growth rate ofS. mutanswas significantly retarded when cocultured withL. acidophilusand the proper concentration of prebiotics. These prebiotics have potential for a clinical application to activate the function of the naturally intraoralL. acidophilusto inhibitS. mutans.

ABSTRACT Objective:The aim of this study was to assess the antimicrobial potency of aqueous extract of Psidium guajava leaves in two different concentrations as a toothbrush disinfectant against three oral bacterial species.Materials and Methods: Aqueous extracts of P. guajava leaves were prepared at 20% and 30% concentrations and 0.2% chlorhexidine was used as control. The toothbrushes were equally divided into 9 groups with 10 toothbrushes per disinfectant, which were contaminated with Streptococcus mutans, Lactobacillus acidophilus, and Enterococcus faecalis. Microbial culture was done after 5 min and 3 h of decontamination.Results: Group Ia and Ib showed that the presence of E. faecalis was observed in 8 (40%) of 20 toothbrushes. Group IIa and IIb showed a significant reduction in colony forming unit/toothbrush during 3 h evaluation. Group IIIa and IIIb showed nil growth during 3 h evaluation. Nil growth was observed with the control group for all three organisms. Statistically significant values were obtained for 5 min (P < 0.001) and 3 h (P < 0.001) disinfection period against L. acidophilus at two different concentrations.Conclusion: Aqueousextracts of guava leaves can be used as an alternative organic product for disinfection of toothbrushes.

ABSTRACT The in vitro activities of human β-defensin 3 (hBD-3) alone or combined with lysozyme, metronidazole, amoxicillin, and chlorhexidine were investigated with the oral bacteria Streptococcus mutans, Streptococcus sanguinis, Streptococcus sobrinus, Lactobacillus acidophilus, Actinobacillus actinomycetemcomitans, and Porphyromonas gingivalis. hBD-3 showed bactericidal activity against all of the bacterial species tested. The bactericidal effect was enhanced when the peptide was used in combination with the antimicrobial agents mentioned above.

Alkyl Polyglucoside

Antimicrobial activity of Usnea barbata especially against bacteria involved in pathogenesis of various skin conditions has been well documented in literature. Nevertheless, there are no papers dealing with formulation of its isolates into topical preparations for treatment of skin infections. In present study, alkyl polyglucoside (APG) - based vehicle was developed as carrier of U. barbata CO2-supercritical extract (U-SE) that demonstrated the best antimicrobial potential in preliminary screening. For comparison, chosen extract in the same concentration and using the same procedure was incorporated into a pharmacopoeial vehicle. Comparative evaluation of physicochemical stability, efficiency and safety proved APG-based vehicle to possess certain preferential features as carrier of U-SE compared to the reference one, composing a topical formulation with potential clinical relevance in treatment of skin infections.
