Regulation of the Porphyromonas gingivalis fimA (Fimbrillin) gene.
In common with many bacterial virulence genes, the fimbrillin (fimA) gene of Porphyromonas gingivalis is modulated in response to environmental fluctuation. The trans-acting components that comprise the regulatory system for transcriptional activity of the fimA gene in P. gingivalis were investigated. Three major proteins were found to bind to the upstream region of the fimA promoter. One of th...
متن کاملPorphyromonas (Bacteroides) gingivalis fimbrillin: size, amino-terminal sequence, and antigenic heterogeneity.
Bacterial fimbriae mediate cell adhesion and are important in colonization. Fimbrial proteins from strains of Porphyromonas (Bacteroides) gingivalis isolated from different individuals were compared for their size, amino-terminal sequence, and antigenic diversity. Two major protein components of the crude fimbrial preparations differed in apparent molecular mass, ranging from 41 to 49 kDa for t...
متن کاملGenome Sequence of Porphyromonas gingivalis Strain A7436.
Porphyromonas gingivalis is strongly associated with periodontitis. P. gingivalis strain trafficking and tissue homing differ widely, even among presumptive closely related strains, such as W83 and A7436. Here, we present the genome sequence of A7436 with a single contig of 2,367,029 bp and a G+C content of 48.33%.
متن کاملGenome Sequence of Porphyromonas gingivalis Strain AJW4.
Porphyromonas gingivalis is associated with oral and systemic diseases. Strain-specific P. gingivalis invasion phenotypes have been correlated with disease presentation in infected laboratory animals. Here, we present the genome sequence of AJW4, a minimally invasive strain, with a single contig of 2,372,492 bp and a G+C content of 48.27%.
متن کاملLactobacillus rhamnosus could inhibit Porphyromonas gingivalis derived CXCL8 attenuation
UNLABELLED An increasing body of evidence suggests that the use of probiotic bacteria is a promising intervention approach for the treatment of inflammatory diseases with a polymicrobial etiology. P. gingivalis has been noted to have a different way of interacting with the innate immune response of the host compared to other pathogenic bacteria, which is a recognized feature that inhibits CXCL8...
