Streptococcus mutans present in a man on a world wide basis (Birgitta Kohler & Douglas Bratthall 1976). High numbers in the mouth of Streptococcus mutans are associated with both high prevalence and a high incidence of dental caries. The Directorate of Oral Health Ministry of Health Republic of Indonesia declared 60 80 percent of school children between 4 14 years by age were suffering from den...

A sequence of 1647 base pairs in length of Streptococcus mutans DNA that encodes for a 63-kDa protein with significant amino acid similarity with fibronectin-binding proteins of Streptococcus pyogenes and Streptococcus gordonii was cloned. The putative recombinant fibronectin-binding protein of S. mutans was purified using affinity chromatography and the cloned protein was used to prepare polyc...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

normal 0 false false false en-us x-none ar-sa background : the beneficial effects of lactobacillus species have been reported but the role of these species including lactobacillus casei (l.casei) on oral health is not well documented. the purpose of this study was to evaluate the effects of conventional or probiotic cheese containing l.casei on salivary streptococcus mutans (sm) and lactobacill...

background: one of the causative factors in development of dental caries is microorganisms. two species of mutans streptococci including streptococcus mutans and streptococcus sobrinus are associated with dental caries in human beings. the aim of this study was to investigate the frequency of s. mutans and s. sobrinus in saliva of children with different caries activity and ability to form biof...

Dental caries-associated oral streptococci are called the mutans streptococci, with Streptococcus mutans and Streptococcus sobrinus being the most prevalent caries-associated organisms in humans. Strains of the mutans streptococci are highly conserved within not only mothers and their children but also racial groups, suggesting vertical transmission of this organism within human populations. It...

UNLABELLED Propolis, a natural antibiotic, is a resinous substance that honey bees (Apis mellifera) produce. The main chemical classes present in propolis are flavonoids, phenolics and other various aromatic compounds. AIM To evaluate the antibacterial action of propolis on the concentration of Streptococcus mutans colonizing the oral cavity of children. MATERIALS AND METHODS Thirty childre...

abstract background: streptococcus mutans in the oral cavities sable to produce mutacin (bacteriocin-like substances) with antibiotic properties. the aim of this study was to investigate the frequency and expression of genes encoding mutacins typei, ii, iii and iv and also two of 8 genes in a cluster encoding the putative bacteriocins, the designated bsm 283, bsm 299, bsm 423, bsm 1889c, bsm 18...

objective: bioactive glass 45s5 is a surface reactive glass-ceramic biomaterial, developed in 1969. bag 45s5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. the aim of this study was to evaluate the antibacterial activity and determine mic and mbc values of nano-bag45s5 on streptococcus muta...

A bacterial agglutinin specific for strains of Streptococcus mutans was isolated from human saliva. Physiochemical analyses showed the agglutinin to be a glycoprotein with a molecular weight of 60,000. The agglutinin aggregated four of the eight strains of Streptococcus mutans tested but did not aggregate the strains of Streptococcus salivarius, Streptococcus sanguis, and Streptococcus mitis te...
