The involvement of CdhR in Porphyromonas gingivalis during Nitric Oxide stress [RNA-seq]

(Submitter supplied) To understand the role of CdhR and its adjacent gene PG1236 in nitric oxide (NO) stress resistance, isogenic mutants P. gingivalis FLL457 (ΔPG1237::ermF), FLL458 (ΔPG1236::ermF) and FLL459 (ΔPG1236-37::ermF) were made by allelic exchange mutagenesis and their gene expression was studied under control and NO stress conditions. DNA microarray analysis of FLL457 showed that approximately 2% of the genes were up regulated and over 1% of the genes down regulated. more...

Role of an extracytoplasmic function sigma factor, PGN_0319, in hemin utilization by Porphyromonas gingivalis

(Submitter supplied) Extracytoplasmic function (ECF) sigma factors are known to play an important role in the bacterial response to various environmental stresses. Porphyromonas gingivalis, a prominent etiological agent in human periodontitis, possesses six putative ECF sigma factors. So far, information is limited on an ECF sigma factor, PGN_0319. It has been recently reported that the expression of genes encoding some of the ECF sigma factors including PGN_0319 was affected by hemin availability. more...

The distinct immune-stimulatory capacities of Porphyromonas gingivalis strains 381 and 33277 are determined by the fimB allele and gingipain activity

(Submitter supplied) The genomes of P. gingivalis strains 33277 and 381 are highly related phylogenetically. However, 33277 displays a reduced capacity to stimulate HEK cell TLR2-dependent signaling and THP-1 cell-dependent IL-1β production compared to 381, suggesting strain-specific differences in the expression of one or more bacterial immune-modulatory cell surface molecules. Genomic sequencing identified a single nucleotide polymorphism in the 33277 fimB allele (A>T), encoding a truncated FimB protein, relative to the 381 fimB allele. more...

Porphyromonas gingivalis 33277 wild-type vs Fur orthologue Har isogenic mutant ECR455

(Submitter supplied) Porphyromonas gingivalis is a major pathogen associated with the microbial biofilm-mediated disease chronic periodontitis. P. gingivalis has an obligate requirement for iron and protoporphyrin IX which it satisfies by transporting heme and iron liberated from the human host. The level of cellular iron in P. gingivalis affects the expression of a distinct iron-associated regulon of 64 genes and low iron invokes an iron sparing response. more...

Role of HcpR in nitrosative stress protection

(Submitter supplied) HcpR has been shown to be required for growth of Porphyromonas gingivalis in the presence of nitrite (Infect Immun. 2012 Sep;80(9):3319-31. doi: 10.1128/IAI.00561-12. Epub 2012 Jul 9). It also has been shown to regulate the expression of hcp. To define the entire regulon of HcpR RNAseq examination of the wild type and mutant (deficient in HcpR) strains have been used to define the regulon in response to nitrite exposure in bacteria grown in the presence and absence of nitrite. more...

Identification of bistable populations of Porphyromonas gingivalis that differ in epithelial cell invasion.

(Submitter supplied) Bistable populations of bacteria give rise to two or more subtypes that exhibit different phenotypes. We have explored whether the periodontal pathogen, Porphyromonas gingivalis, exhibits bistable invasive phenotypes. Using a modified cell invasion assay, we show for the first time that there are two distinct sub-types within a population of P.ginigivalis strains NCTC 11834 and W50 that display differences in their ability to invade oral epithelial cells. more...
