13. Effective immunity to dental caries: protection of malnourished rats by local injection of Streptococcus mutans.
When rats from dams fed a low-protein diet were injected with whole, killed Strepococcus mutans 6715 cells in the region of the submandibular gland, they developed serum and salivary agglutinins to this microorganism. Titers of agglutinins in malnourished rats were similar to those observed in rats from dams fed a nutritionally adequate diet that were locall

14. Initial colonization of teeth in monkeys as related to diet.
The initial phases of plaque development on nonretentive tooth surfaces were studied bacteriologically in Macaca irus monkeys fed by stomach tube and provided with various oral supplements. Except for the oral implantation of Streptococcus mutans in some of the animals, the oral flora was not changed prior to the studies. Dental plaque was allowed to develop

15. Microflora and chemical composition of dental plaque from subjects with hereditary fructose intolerance.
We compared the microbiological and chemical composition of dental plaque from subjects with hereditary fructose intolerance who restrict their dietary sugar intake with that of control subjects who do not. The two groups showed no significant differences in chemical composition of plaque: the mean protein, carbohydrate, calcium, magnesium, and phosphate con

16. Molecular analysis of a Streptococcus mutans strain exhibiting polymorphism in the tandem gtfB and gtfC genes.
Streptococcus mutans UA101, which was previously demonstrated to be highly cariogenic in gnotobiotic rats, exhibited much lower water-insoluble glucan (IG) synthetic activity compared with that of S. mutans GS5 and was unable to express sucrose-dependent colonization of smooth surfaces in vitro. On the basis of Southern and Western blot (immunoblot) analyses

17. Role of a cell surface-associated protein in adherence and dental caries.
Insertional inactivation of the Streptococcus mutans spaP gene was used to construct an isogenic mutant (834) of strain NG8 (serotype c) which lacked the major cell surface-associated protein referred to as P1 (15). Results of several studies suggest that P1 is involved in the adherence of S. mutans to saliva-coated apatite surfaces. With an in vitro model s

18. Passive Transfer of Immunoglobulin Y Antibody to Streptococcus mutans Glucan Binding Protein B Can Confer Protection against Experimental Dental Caries
Active immunization with Streptococcus mutans glucan binding protein B (GBP-B) has been shown to induce protection against experimental dental caries. This protection presumably results from continuous secretion of salivary antibody to GBP-B, which inhibits accumulation of S. mutans within the oral biofilm. The purpose of this study was to explore the influe
