... fluoride (NH 4 F) could affect hydrophobicity and adhesion of Streptococcus sanguis and Streptococcus mutans to saliva-coated hydroxyapatite (S-HA). Determination of the minimum inhibitory concentrations (MICs) showed that both species were susceptible to all agents tested. Growth in the presence of sub...

... of mutans streptococci after suppression by the agent. We have tested this hypothesis in gnotobiotic rats associated with Streptococcus mutans alone, or associated with S. mutans and strains of Streptococcus oralis , Streptococcus sanguis , Streptococcus gordonii , Streptococcus mitis biovar I...

...R.K. Rose Calcium bound by oral bacteria may have important effects on plaque cohesion and mineral dynamics. Equilibrium dialysis was used here to study the effect of magnesium and zinc competition on calcium-binding by Streptococcus sanguis 7863. Experiments were carried out using 45 Ca in 0.1–5.0...

... values at 1 month, and a significant increase above baseline values at 3 months, (p < 0.001). There was no significant change in saliva volume, in total numbers of facultatively anaerobic bacteria, or in levels of lactobacilli or Streptococcus sanguis . This treatment system is capable of significant...

... (6.5), MIC values were 4 or 8 µg/ml for Streptococcus mutans , Streptococcus sobrinus,Streptococcus sanguis , Actinomyces viscosus and Actinomyces naeslundii . MIC values were 0.125–0.50 mmol Zn/ml. MBC values ranged from 1 to 8 mmol Zn/ml at pH 5.5. Isobologram data revealed that sanguinarine and zinc...

...E. Giertsen; A.A. Scheie; G. Rölla Bacteriological tests demonstrated an additive inhibitory effect of ZnCl 2 and sodium lauryl sulfate (SLS) on in vitro growth of Streptococcus sobrinus OMZ 176 and of Streptococcus sanguis ATCC 10556. As measured by atomic absorption spectrophotometry...

...W. Distler; A. Kagermeier; R. Hickel; A. Kröncke Lactate influx was measured in Streptococcus sanguis and in several strains of Streptococcus mutans by comparing the intra- and extracellular distribution of ( l4 C)-lactate. Lactate efflux was followed enzymatically against rising external lactate...

... chromatography and by biochemical methods. These glucans were tested for their ability to initiate and support growth of S. mutans IB and Streptococcus sanguis 903. S. sanguis 903 could grow with the low molecular weight glucan at a reduced rate compared with glucose. S. mutans IB could not utilize any...

...Ann S. McDermid; P.D. Marsh; C.W. Keevil; D.C. Ellwood The effect of 0.07 or 0.15 m M chlorhexidine (CHX) and 4.0 or 8.0 m M potassium fluoride (F), added singly and in combinations, on acid production by Streptococcus mutans and Streptococcus sanguis was studied. Cells were grown in a chemostat...

...M.J.M. Schaeken; M.H. de Jong; H.C.M. Franken; J.S. van der Hoeven Localized areas of the dentition in human volunteers were treated once with chlorhexidine or iodine. Plaque samples taken from the experimental surfaces were analyzed for the number of Streptococcus mutans , Streptococcus sanguis...

... species, Veillonella, Streptococcus mutans, Streptococcus sanguis , and Lactobacillus species were detected in a range from 300 to 5 × 10 7 colony-forming units per plaque sample. S. mutans and lactobacilli were found to be the most numerically stable of the species investigated, and high numbers...

... 11 patients. In these persons, however, higher percentages of Streptococcus mutans and lactobacilli and a lower percentage of Streptococcus sanguis of total cultivable flora were found in plaque samples from abutments of loose retainers compared to in plaque samples from cemented retainers...

...H. Baba; S. Igarashi; A. Kamaguchi The dental plaques of 20 young children were examined for bacteria having lytic activity against Streptococcus sanguis ATCC 10556, 10557, and 10558. Bacteria showing lytic activity against S. sanguis ATCC 10558 alone were isolated from dental plaques of all...

...F.H.M. Mikx; J.S. van der Hoeven; A.J.M. Plasschaert; K.G. König The effect of the inoculation sequence of Actinomyces viscosus Ny 1 and Streptococcus sanguis Ny 101 on the establishment of Streptococcus mutans OMZ 176E was investigated in germ-free rats on diets with different sucrose...

...W.J. Loesche; R.J. Murray; J.R. Mellberg The percentage of Streptococcus mutans and Streptococcus sanguis in interproximal plaque following 5–10 daily applications of either an acidulated phosphate fluoride (APF) gel or a placebo gel was determined. Institutionalized boys, 14–16 years of age...

...Urban Forsum; Kenneth Holmberg An immunofluorescence method for the identification of Streptococcus sanguis in human dental plaque has been developed, using FITC-labelled F(ab′)2-fragments of IgG, with optimal staining characteristics. The predominant Strep. sanguis serotype in human dental plaque...
