Differentiation of banding patterns between Streptococcus mutans and Streptococcus sobrinus isolates in rep-PCR using ERIC primer

Journal of Oral Microbiology, 2011
Streptococcus mutans and Streptococcus sobrinus are considered to be important bacterial species in the initiation of human dental caries. Therefore, the establishment of a reliable genotyping method to distinguish S. mutans from S.

Penetration of Streptococcus sobrinus and Streptococcus sanguinis into dental enamel

Anaerobe, 2015
The aim of this pilot study was to assess the difference in virulence of acidogenic and aciduric oral streptococci in an in vitro caries model using their penetration depths into dental enamel. 30 caries-free extracted molars from 11- to 16-year-olds were cleaned ultrasonically for 1 min with de-ionized water and, after air-drying, embedded in epoxy ...

Glucosyltransferase from Streptococcus sobrinus Catalyzes Glucosylation of Catechin [PDF]

Applied and Environmental Microbiology, 1995
We previously showed that the polymeric forms of polyphenols present in oolong tea extract exhibited strong inhibitory activities against glucosyltransferases (GTases) of mutans streptococci, while green tea extract, which is rich in catechins, did not show such GTase-inhibitory activities.

Adaptive Acid Tolerance Response of Streptococcus sobrinus [PDF]

Journal of Bacteriology, 2004
ABSTRACT Streptococcus mutans and Streptococcus sobrinus are the bacteria most commonly associated with human dental caries. A major virulence attribute of these and other cariogenic bacteria is acid tolerance. The acid tolerance mechanisms of S.
