..., mostly Streptococcus salivarius , displayed a continuum of acid tolerance thresholds ranging from pH 4.55 to 3.39, but amino acid alignments of F 1 F 0 -ATPase subunits revealed few non-synonymous substitutions and these were unrelated to acid tolerance. Thus, the F 1 F 0 -ATPase is highly-conserved...

.... A miniature pH electrode was placed on the tooth, and Streptococcus mutans NCTC 10449 cells, grown in 0.5% glucose-containing complex medium, were packed into the well. The pH at the tooth/ S. mutans interface was monitored continuously for 120 min after the addition of 0.5% glucose at 37°C. S. mutans cells...

...%) and Lactobacillus fermentum (52%). No differences were found in the prevalence rates of the most frequent target species in the 3 layers. The most prevalent taxa found at levels above 10 5 in the advanced front line of deep-dentin caries were Atopobium genomospecies C1, F. nucleatum , Streptococcus mutans...

... is sparse. We compared the ability of Streptococcus and Actinomyces species to adhere to hydroxyapatite coated by rat saliva (rsHA) and human saliva (sHA). We also explored the influence of glucan synthesized in situ on the adherence of organisms. We show that each strain of organism has a distinct binding...
