Streptococcus gordonii Modulates Candida albicans Biofilm Formation through Intergeneric Communication
ABSTRACT The fungus Candida albicans colonizes human oral cavity surfaces in conjunction with a complex microflora. C. albicans SC5314 formed biofilms on saliva-coated surfaces that in early stagesExpand

Glucan-binding proteins of the oral streptococci.
The synthesis of extracellular glucan is an integral component of the sucrose-dependent colonization of tooth surfaces by species of the mutans streptococci. In investigators' attempts to understandExpand

Survival and implantation of Escherichia coli in the intestinal tract.
Preliminary experiments established that a 0.5-ml inoculum that is introduced directly into the stomach of mice was cleared rapidly into the small intestine. Bicarbonate buffer, but not skim milk,Expand

Phylogenetic analysis of bacterial and archaeal species in symptomatic and asymptomatic endodontic infections.
Phylogenetic analysis of bacterial and archaeal 16S rRNA was used to examine polymicrobial communities within infected root canals of 20 symptomatic and 14 asymptomatic patients. Nucleotide sequencesExpand

Genome-wide transcriptional changes in Streptococcus gordonii in response to competence signaling peptide.
Streptococcus gordonii is a primary colonizer of the multispecies biofilm on tooth surfaces forming dental plaque and a potential agent of endocarditis. The recent completion of the genome sequenceExpand

Interaction of Candida albicans Cell Wall Als3 Protein with Streptococcus gordonii SspB Adhesin Promotes Development of Mixed-Species Communities
ABSTRACT Candida albicans colonizes human mucosa and prosthetic surfaces associated with artificial joints, catheters, and dentures. In the oral cavity, C. albicans coexists with numerous bacterialExpand

Streptococcus gordonii glucosyltransferase promotes biofilm interactions with Candida albicans
Background Candida albicans co-aggregates with Streptococcus gordonii to form biofilms and their interactions in mucosal biofilms may lead to pathogenic synergy. Although the functions ofExpand

Regulation of gene expression in a mixed-genus community: stabilized arginine biosynthesis in Streptococcus gordonii by coaggregation with Actinomyces naeslundii.
Interactions involving genetically distinct bacteria, for example, between oral streptococci and actinomyces, are central to dental plaque development. A DNA microarray identified StreptococcusExpand

Nucleotide sequence analysis of the Streptococcus gordonii glucosyltransferase gene, gtfG.
Streptococcus gordonii has an extracellular glucosyltransferase (GTF) that polymerizes the glucose moiety of sucrose to form both water-soluble and water-insoluble glucans. Whereas multiple gtf genesExpand

Changes in the carboxyl-terminal repeat region affect extracellular activity and glucan products of Streptococcus gordonii glucosyltransferase.
Glucans produced by the glucosyltransferase (GTF) of Streptococcus gordonii confer a hard, cohesive phenotype (Spp+) on colonies grown on sucrose agar plates. S. gordonii strains with specificExpand
