Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

Periodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.

Identification of Streptococcus sobrinus with monoclonal antibodies [PDF]

Journal of Clinical Microbiology, 1987
Identification of Streptococcus sobrinus is often difficult to perform because of the great resemblance of the organism to other oral streptococcal species. Therefore, monoclonal antibodies were prepared which were shown to be highly specific for S. sobrinus.

PCR for detection and identification of Streptococcus sobrinus [PDF]

Journal of Medical Microbiology, 2000
Oligonucleotide primers were designed based upon a comparison of the dextranase gene (dex) sequences from Streptococcus sobrinus and S. mutans. The primers amplified a 1610-bp long DNA fragment on the dex gene by a PCR. The pair of primers was specific to S. sobrinus as the other members of the mutans streptococci - S. mutans, S. downei, S. cricetus, S.

The antibacterial effects of vitamin D3 against mutans streptococci: an in vitro study

European Oral Research, 2021
Purpose This study aims to evaluate the antimicrobial effects of the cholecalciferol vitamin D3 against Streptococcus sobrinus (Strep. sobrinus) and Streptococcus mutans (Strep.

Overproduction of a dextranase inhibitor by Streptococcus sobrinus mutants [PDF]

Journal of Bacteriology, 1994
An inhibitor of Streptococcus sobrinus endodextranase was detected in the extracellular fractions of UAB66 mutants identified following ethyl methanesulfonate mutagenesis as either devoid of dextranase activity (Dex-) or overproducing water-soluble glucan.

Genotypic Variations of Mutans Streptococci Isolated from Dental Caries by REP-PCR

مجلة بغداد للعلوم, 2020
Mutans streptococci (MS) are a group of oral bacteria considered as the main cariogenic organisms. MS consists of several species of genus Streptococcus which are sharing similar phenotypes and genotypes. The aim of this study is to determine the genetic

Multiple glucan-binding proteins of Streptococcus sobrinus [PDF]

Journal of Bacteriology, 1996
Several proteins from culture supernatants of Streptococcus sobrinus were able to bind avidly to Sephadex G-75. The proteins could be partially eluted from the Sephadex by low-molecular-weight alpha-1,6 glucan or fully eluted by 4 M guanidine hydrochloride.

Determining the Antibacterial Effect of Mentha Longifolia Essential Oil on Cariogenic Bacteria and Its Compounds: an in vitro Study [PDF]

Journal of Dentistry, 2023
Statement of the Problem: Continuous use of chemical agents to reduce the number of cariogenic bacteria leads to adverse effects; therefore, in recent years, many studies have focused on plant-based substances.

Purification of a fourth glucosyltransferase from Streptococcus sobrinus [PDF]

Journal of Bacteriology, 1989
Recently, we found a novel primer-independent, water-soluble glucan synthase as a fourth glucosyltransferase (GTF) in a culture supernatant of strain AHT-k of Streptococcus sobrinus (Y. Yamashita, N. Hanada, and T. Takehara, Biochem. Biophys. Res. Commun. 150:687-693, 1988).

Oral immunization of humans with Streptococcus sobrinus glucosyltransferase [PDF]

Infection and Immunity, 1987
The effect of oral administration of glucosyltransferase (GTF) from Streptococcus sobrinus 6715 on levels of immunoglobulin A (IgA) antibody to GTF in parotid saliva and on the number of indigenous Streptococcus mutans in the whole saliva was studied in young adult males.
