Autor: John F. McCabe, Kaoru Ohmori, Roy R. B. Russell, Nobuko Maeda, Satoshi Imazato, Yasuko Momoi

Publikováno v: Dental Materials Journal. 27:145-148

In this study, the bactericidal activity of antibacterial monomer MDPB (12-methacryloyloxydodecylpyridinium bromide) against Streptococcus mutans was tested by a rapid method for monitoring viability. To S. mutans culture containing fluorescence stai

Comparative genome hybridization of Streptococcus mutans strains

Autor: Daniel Swan, Janet Waterhouse, Roy R. B. Russell

Publikováno v: Oral Microbiology and Immunology. 22:103-110

The basis for genotypic and phenotypic variation within Streptococcus mutans is poorly understood but the availability of the genome sequence of strain UA159 provides an opportunity for comparative studies. Genomic DNA prepared from nine strains of S

Genomic variation in Streptococcus mutans: deletions affecting the multiple pathways of β-glucoside metabolism

Autor: S. Lowes, Roy R. B. Russell, L. A. Old

Publikováno v: Oral Microbiology and Immunology. 21:21-27

The genome of Streptococcus mutans UA159 contains two phospho-beta-glucosidase genes, bglA and celA, which occur in operon-like arrangements along with genes for components of phosphotransferase transport systems and a third phospho-beta-glucosidase

Conserved Repeat Motifs and Glucan Binding by Glucansucrases of Oral Streptococci and Leuconostoc mesenteroides

Autor: Gilles Joucla, Roy R. B. Russell, Deepan S. H. Shah, Magali Remaud-Simeon

Publikováno v: Journal of Bacteriology. 186:8301-8308

Glucansucrases of oral streptococci and Leuconostoc mesenteroides have a common pattern of structural organization and characteristically contain a domain with a series of tandem amino acid repeats in which certain residues are highly conserved, part

A novel glucan-binding protein with lipase activity from the oral pathogen Streptococcus mutans

Autor: Roy R. B. Russell, Deepan S. H. Shah

Publikováno v: Microbiology. 150:1947-1956

Streptococcus mutansproduces extracellular glucosyltransferases (GTFs) that synthesize glucans from sucrose. These glucans are important in determining the permeability properties and adhesiveness of dental plaque. GTFs and the GbpA glucan-binding pr

Chromosomal Insertions and Deletions in Streptococcus mutans

Autor: W G Robinson, Deepan S. H. Shah, Roy R. B. Russell, L A Old

Publikováno v: Caries Research. 37:148-156

Many isolates of Streptococcus mutans lack the ability to ferment melibiose and other sugars. We previously reported that this was commonly due to a chromosomal deletion and, in the present study, sequence information from the S. mutans genome projec

Molecular mediators of Porphyromonas gingivalis -induced T-cell apoptosis

Autor: Roy R. B. Russell, J. I. Harris, John J. Taylor, J. Aduse-Opoku, M. A. Curtis

Publikováno v: Oral Microbiology and Immunology. 17:224-230

Porphyromonas gingivalis produces virulence factors which can modify the molecular and cellular components of the host immune response. In the present work we investigated the role of specific virulence factors from P. gingivalis in the induction of

Inhibition of Catalytic and Glucan-Binding Activities of a Streptococcal GTF Forming Insoluble Glucans

Autor: Wanda G. Wright, Birte Svensson, C. Thelwell, Roy R. B. Russell

Publikováno v: Caries Research. 36:353-359

The ability of a range of potential inhibitors to affect the catalytic activity or binding of dextran by a glucosyltransferase (GTF-I) that synthesises insoluble α1,3-linked glucan was tested. Acarbose, deoxynojirimycin, N-dodecyldeoxynojirimycin an
