| comparative effect of photodynamic therapy on separated or mixed cultures of streptococcus mutans and streptococcus sanguinis. | antimicrobial photodynamic therapy (apdt) has shown to exert a bactericidal effect against streptococcus sanguinis and streptococcus mutans. however, this efficacy has been reported for either type of bacteria separately. bacterial suspensions of both strains, separately or together, were treated with concentrations of methylene blue (mb) and rose bengal (rb). suspensions were irradiated with a light-emitting diode lamp (λ center at 625nm for mb and λ center at 515nm for rb) using a fluence of 1 ... | 2017 | 28546111 |
| is spxa2 involved in hydrogen peroxide production and competence development in streptococcus sanguinis? | the objective of the present study was to investigate whether streptococcus sanguinis spxa2 plays a role in competence development and endogenous h2o2 generation, and whether the spxa2 cys10-xx-cys13 (cxxc) motif is involved in competence development. | 2017 | 28693663 |

| non-thermal atmospheric pressure plasma functionalized dental implant for enhancement of bacterial resistance and osseointegration. | even though roughened titanium (ti) and ti alloys have been clinically used as dental implant, they encourage bacterial adhesion, leading to failure of the initial stability. here, the non-thermal atmospheric pressure plasma jet (ntappj) functionalized ti and ti alloy were investigated to promote cellular activities but inhibit the initial attachment of the adherent pioneer bacterium, streptococcus sanguinis, without topographical changes. | 2017 | 28088458 |
| tetr family regulator brpt modulates biofilm formation in streptococcus sanguinis. | biofilms are a key component in bacterial communities providing protection and contributing to infectious diseases. however, mechanisms involved in s. sanguinis biofilm formation have not been clearly elucidated. here, we report the identification of a novel s. sanguinis tetr repressor, brpt (biofilm regulatory protein tetr), involved in biofilm formation. deletion of brpt resulted in a significant increase in biofilm formation. interestingly, the mutant accumulated more water soluble and water ... | 2017 | 28046010 |
| antibacterial activity and biofilm inhibition by surface modified titanium alloy medical implants following application of silver, titanium dioxide and hydroxyapatite nanocoatings. | one of the most common causes of implant failure is peri-implantitis, which is caused by bacterial biofilm formation on the surfaces of dental implants. modification of the surface nanotopography has been suggested to affect bacterial adherence to implants. silver nanoparticles are also known for their antibacterial properties. in this study, titanium alloy implants were surface modified following silver plating, anodisation and sintering techniques to create a combination of silver, titanium di ... | 2017 | 28281851 |

| streptococcus sanguinis induces neutrophil cell death by production of hydrogen peroxide. | streptococcus is the dominant bacterial genus in the human oral cavity and a leading cause of infective endocarditis. streptococcus sanguinis belongs to the mitis group of streptococci and produces hydrogen peroxide (h2o2) by the action of spxb, a pyruvate oxidase. in this study, we investigated the involvement of spxb in survival of s. sanguinis in human blood and whether bacterial h2o2 exhibits cytotoxicity against human neutrophils. results of a bactericidal test with human whole blood reveal ... | 2017 | 28222125 |
| does current cefazolin dosing achieve adequate tissue and blood concentrations in obese women undergoing cesarean section? | prophylactic administration of antibiotics preceding cesarean delivery is the most effective measure taken for preventing postpartum infection. while obese women are at greater risk for infection than non-obese women, evidence-based recommendations for modifying dosing in these women are limited. | 2017 | 28122314 |
| activation of nucleotide-binding domain-like receptor containing protein 3 inflammasome in dendritic cells and macrophages by streptococcus sanguinis. | streptococcus sanguinis is frequently isolated from the blood of patients with infective endocarditis and contributes to the pathology of this disease through induction of interleukin (il)-1β responsible for the development of the disease. however, the mechanism of il-1β induction remains unknown. in this study, s. sanguinis activated a murine dendritic cell (dc) to induce il-1β and this activity was attenuated by silencing the mrnas of nucleotide-binding domain-like receptor containing protein ... | 2017 | 27601185 |
| characterization of non-dialyzable constituents from cranberry juice that inhibit adhesion, co-aggregation and biofilm formation by oral bacteria. | an extract prepared from cranberry juice by dialysis known as nondialyzable material (ndm) has been shown previously to possess anti-adhesion activity toward microbial species including oral bacteria, uropathogenic escherichia coli and helicobacter pylori. bioassay-guided fractionation of cranberry ndm was therefore undertaken to identify the anti-adhesive constituents. an aqueous acetone-soluble fraction (ndmac) obtained from sephadex lh-20 inhibited adhesion-linked activities by oral bacteria, ... | 2017 | 28470309 |
| microbiome associated with severe caries in canadian first nations children. | young indigenous children in north america suffer from a higher degree of severe early childhood caries (s-ecc) than the general population, leading to speculation that the etiology and characteristics of the disease may be distinct in this population. to address this knowledge gap, we conducted the first microbiome analysis of an indigenous population using modern molecular techniques. we investigated the caries-associated microbiome among canadian first nations children with s-ecc. thirty firs ... | 2017 | 28709393 |
| effect of arginine on the growth and biofilm formation of oral bacteria. | alkali production via arginine deiminase system (ads) of oral bacteria plays a significant role in oral ecology, ph homeostasis and inhibition of dental caries. ads activity in dental plaque varies greatly between individuals, which may profoundly affect their susceptibility to caries. | 2017 | 28668766 |
| the evaluation of cultivable microbiota profile in patients with secondary endodontic infection before and after photo-activated disinfection. | secondary/persistent endodontic infection can be the outcome of failure of endodontic treatment. photo-activated disinfection (pad) can be a useful adjunct to mechanical and antimicrobial agents in eliminating endopathogenic microorganisms. in this study, we evaluated the effect of pad on diversity and count of microbiota related to secondary/persistent endodontic infections. | 2017 | 28249746 |

| the miia motif is a common marker present in polytopic surface proteins of oral and urinary tract invasive bacteria. | many surface virulence factors of bacterial pathogens show mosaicism and confounding phylogenetic origin. the streptococcus gordonii platelet-binding gspb protein, the streptococcus sanguinis srpa adhesin and the streptococcus pneumoniae diia protein, share an imperfect 27-residue motif. given the disparate domain architectures of these proteins and its association to invasive disease, this motif was named miia from multiarchitecture invasion-involved motif a. miia is predicted to adopt a beta-s ... | 2017 | 28167145 |
