Typing of Streptococcus mutans strains isolated from caries free and susceptible subjects by multilocus enzyme electrophoresis

The Comparison of Proteins Elaborated by Streptococcus mutans Strains Isolated from Caries Free and Susceptible Subjects

The Comparison of Proteins Elaborated by Streptococcus mutans Strains Isolated from Caries Free and Susceptible Subjects

OBJECTIVE(S) The oral streptococci especially mutans Streptococci are related with the development of caries in humans. However, they are commonly distributed not only in populations with moderate or high caries incidence but also in populations having no or low caries experience. So, in this study, the differences between protein profiles of Streptococcus mutans from different sources were com...

Genotypic diversity and virulence traits of Streptococcus mutans in caries-free and caries-active individuals.

The present study evaluated the relationship between clonal diversity and some virulence traits of Streptococcus mutans isolated from eight caries-free and eight caries-active subjects. A total of 155 S. mutans isolates from caries-free subjects and 144 isolates from caries-active subjects were obtained from samples of saliva, dental plaque and tongue surface and identified by PCR. The isolates...

The Frequency of Streptococcus Mutans and Lactobacillus spp.in 3-5-year- old Children with and without Dental Caries

Abstract Background and Objective: The high occurrence of early childhood caries (ECC) is one of the most common problems in children dentistry. Streptococcus mutans and lactobacilli.spp are closely associated with the development of early childhood caries (ECC). Therefore, the aim of this study was to investigate the frequency of streptococcus mutans and lactobacilli.spp in 3-5 –year- old ch...

Antigenic characterization of fimbria preparations from Streptococcus mutans isolates from caries-free and caries-susceptible subjects.

The adhesion of pathogenic bacteria to the host surface is an essential step in the development of numerous infections, including dental caries. Attachment of Streptococcus mutans, the main etiological agent of human dental caries, to the tooth surface may be mediated by glucan synthesized by glucosyltransferase (GTF) and by cell surface proteins, such as P1, which bind to salivary receptors. F...
