Anti-Adhesins of Streptococcus Sobrinus
1996Several members of the genus Streptococcus seem to be able to elaborate surface lectins. The oral streptococci have been reported to bind sialic acid ( S. sanguis) and α-glucans (Gibbons and Fitzgerald 1969). The organisms capable of binding α-glucans include S. cricetus and S. sobrinus. A few members of the highly cariogenic S. mutans also can complex

A DNA probe specific to Streptococcus sobrinus
Oral Microbiology and Immunology, 1999Three DNA fragments (SSB‐1, ‐2 and ‐3) in the dextranase gene (dex) of Streptococcus sobrinus were amplified by polymerase chain reaction and used as DNA probes. The probes were examined for the specificity and the sensitivity of hybridization with DNA of oral streptococcal species. While probes SSB‐1 and SSB‐2 were specific to both S.

Streptococcus sobrinus is known to possess cariogenic properties in vitro. It can produce acid in large amounts and it has the capacity to adhere to enamel and other surfaces. However, most studies on cariogenicity have been performed with laboratory strains that have been subcultured over long periods of time.

Polycarboxylates inhibit the glucan-binding lectin of Streptococcus sobrinus
Biochimica et Biophysica Acta (BBA) - General Subjects, 2000Polycarboxylates, such as carboxymethylcellulose and hyaluronan, were found to be reversible inhibitors of the glucan-binding lectin of Streptococcus sobrinus. When the carboxylate groups were coupled to ethylenediamine, or reduced with carbodiimide-borohydride, inhibitory powers were lost.

Streptococcus sobrinus in children and its influence on caries activity
European Archives of Paediatric Dentistry, 2006This was to study the longitudinal assessment of caries activity of Streptococcus sobrinus (SS) positive children during their mixed dentition.The occurrence of mutans streptococci (MS) in plaque and saliva was determined in a representative sample of 55 children aged 8 to 12 years over a period of 4 years. A total of 708 bacterial strains was isolated

Effect of Desalivation and Age on Susceptibility to Infection by Streptococcus sobrinus
Caries Research, 2009The influence of desalivation and age on susceptibility to infection by Streptococcus sobrinus was studied using 80 Sprague-Dawley female rats weaned at age 21 days. Forty animals (donors) were infected with S. sobrinus 6715 (ATCC 27352), formed into ten groups of 4, fed diet 2000, and offered 10% sucrose water ad libitum. The remaining 40 animals were

Effect of Monoclonal Antibodies on the Colonization of Rats by Streptococcus sobrinus
Caries Research, 2009Local passive immunization has been suggested as a method of preventing colonization of teeth by mutans streptococci. In this study we describe the effect of local application of monoclonal antibodies (Mabs) on the colonization of Streptococcus sobrinus.

Effect of Antibodies on the Chain Length and Growth of Streptococcus sobrinus
Caries Research, 2009Passive immunization has been suggested as a method to prevent colonization of teeth by mutans streptococci. However, the mechanism of action of antibodies, both polyclonal and monoclonal, is not clear. In this study we investigated the effect of polyclonal antibodies (pAbs) and a monoclonal antibody (OMVU10) on the chain length and growth of ...

Dental Location of Streptococcus mutans and Streptococcus sobrinus in Human: Harboring Both Species
Caries Research, 2009The distribution and prevalence of Streptococcus mutans and Streptococcus sobrinus were determined in plaque samples from the cervical areas of all buccal, lingual and approximal tooth surfaces and from the fissures of all occlusal sites in 40 subjects harboring both species. S. mutans was detected more often and in higher numbers than S.

The effect of sugar restriction on the oral levels of mutans streptococci was studied in 20 subjects fulfilling three criteria: (1) having more than 300,000 CFU mutans streptococci/ml saliva, (2) harbouring both Streptococcus mutans and Streptococcus sobrinus in saliva, and (3) eating sugar frequently.
