Genotypic diversity and cariogenicity of Candida albicans from children with early childhood caries and caries-free children
BACKGROUND The genotypic diversity and cariogenicity of C. albicans from the dental plaque of children are poorly understood. This study aimed to explore the genotypic diversity and cariogenicity of C. albicans from children with early childhood caries and caries-free children. METHODS Dental plaque samples from 238 children with early childhood caries and from 125 caries-free children were c...
متن کاملGenotypic Diversity of Streptococcus mutans in Caries-Free and Caries-Active Preschool Children
Aim. The aim of the present paper was to evaluate the genotypic diversity of S. mutans in caries-free and caries-active preschool children in Brazil. Design. Twenty-eight preschool children were examined regarding caries experience by the dmft index. DNA from 280 isolates of S. mutans was extracted. S. mutans evaluated using to the PCR method, with primers for the glucosyltransferase gene. The ...
متن کاملGenotypic Diversity and Virulence Factors of Streptococcus mutans in Caries-free and Caries-active Individuals
The objective of this study was to analyze the genotypic diversity, frequency of serotypes and the detection of mutacins from Streptococcus mutans isolates in caries-free and caries-active individuals. A total of 260 S. mutans isolated from 28 individuals with and without dental caries were subjected to AP-PCR and PCR screening of glucosyltransferase B, mutacin and serotype genes, which showed ...
متن کاملGenotypic 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...
متن کاملGenotypic diversity and virulence traits of streptococcus sobrinus isolated from caries-free children and children suffering severe early childhood caries.
OBJECTIVE To evaluate the genotypic diversity and some virulence traits of Streptococcus sobrinus (S. sobrinus) isolated from caries-free children and children suffering severe early childhood caries (SECC). METHODS S. sobrinus isolated from stimulated whole saliva samples of 91 caries-free children and 87 SECC children were subcultured, identified by polymerase chain reaction and genotyped b...
