Susceptibility of Streptococcus mutans to antimicrobial agents.
Fifty strains of Streptococcus mutans, including defined strains and clinical isolates, were tested for susceptibility to 20 different antimicrobial agents. Minimal inhibitory concentrations were determined by a liquid microtiter procedure. Antibiotics that were most effective in concentrations below 0.1 mug/ml included penicillin, ampicillin, erythromycin, cephalothin, and methicillin. Antibio...
متن کاملNovel synthetic antimicrobial peptides against Streptococcus mutans.
Streptococcus mutans, a common oral pathogen and the causative agent of dental caries, has persisted and even thrived on the tooth surface despite constant removal and eradication efforts. In this study, we generated a number of synthetic antimicrobial peptides against this bacterium via construction and screening of several structurally diverse peptide libraries where the hydrophobicity and ch...
متن کاملInhibition of dextransucrase activity in Streptococcus mutans by plant phenolics.
Streptococcus mutans is responsible for causing dental caries in humans and utilizes sucrose for its growth. The dextransucrase (EC 2.4.1.5) is responsible for sucrose metabolism, which exhibits both hydrolytic and glucosyltransferase activities. In this study, we examined the effects of the plant phenols, namely gallic, tannic and syringic acids and aqueous extracts of certain traditionally us...
متن کاملIn vitro inhibition of adherence of Streptococcus mutans strains by nonadherent mutants of S. mutans 6715.
Four nonadherent mutants from Streptococcus mutans 6715 mutant UAB66 (serotype g) with similar phenotypes were shown to inhibit the adherence of adherence-proficient S. mutans serotypes c and g strains. One mutant, UAB108, was shown to inhibit adherence by wild-type strains representing serotypes a, d, and e as well. This inhibition of adherence was seen with pairs of strains grown in partially...
متن کاملinvestigation of probiotic chocolate effect on streptococcus mutans growth inhibition
background one of the most important factors in inducing the logarithmic growth of streptococcus mutans, is a diet containing fermentable carbohydrates such as sucrose. objectives: the aim of the current research was to compare the ability of ordinary and probiotic chocolate to induce or inhibit the growth of s. mutans. materials and methods lactobacillus rhamnosus, l. plantarum and l. acidophi...
