Distribution of Porphyromonas gingivalis fimA and mfa1 fimbrial genotypes in subgingival plaques [PDF]

PeerJ, 2018
Background Strains of periodontal disease-associated bacterium Porphyromonas gingivalis have different pathogenicity, which can be attributed to clonal genetic diversity. P.

Glucose depletion enables Candida albicans mating independently of the epigenetic white-opaque switch [PDF]

Nature Communications, 2023
The human fungal pathogen Candida albicans can switch stochastically and heritably between a “white” phase and an “opaque” phase. Opaque cells are the mating-competent form of the species, whereas white cells are thought to be essentially “sterile”. Here,

Giant honeybees (Apis dorsata) trade off defensiveness against periodic mass flight activity. [PDF]

PLoS ONE
The giant honeybee Apis dorsata (Fabricius, 1793) is an evolutionarily ancient species that builds its nests in the open. The nest consists of a single honeycomb covered with the bee curtain which are several layers of worker bees that remain almost ...

Tobacco Smoke Augments Porphyromonas gingivalis - Streptococcus gordonii Biofilm Formation

PLoS ONE, 2011
Smoking is responsible for the majority of periodontitis cases in the US and smokers are more susceptible than non-smokers to infection by the periodontal pathogen Porphyromonas gingivalis. P.

Antibacterial Activity, Antiadherence Activity, Antioxidant Activity, and Molecular Docking of Sweetbrair Rose (Rosa Rubiginosa) Extract on Periodontopathogens: Porphyromonas Gingivalis and Aggregatibacter Actinomycetemcomitans – An In Vitro Study

Journal of Pharmacy and Bioallied Sciences
Introduction: Rosa rubiginosa extracts were prepared, and the antibacterial and anti-biofilm assays were investigated against two different periodontics-causing bacteria for the first time. The aim was to determine whether the extracts could restrict the

cAMP-independent Crp homolog adds to the multi-layer regulatory network in Porphyromonas gingivalis [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionPorphyromonas gingivalis encodes three CRP/FNR superfamily proteins: HcpR, PgRsp, and CrpPg, with CrpPg similar to cAMP-sensing proteins but not classified into known families.

In Silico Destruction of Porphyromonas gingivalis Fimbriae by Streptomyces sp. Strain GMY02 [PDF]

BIO Web of Conferences, 2023
Porphyromonas gingivalis, a keystone pathogen in chronic periodontitis, has fimbria as one of the most important virulence factors because it plays a vital role in the pathogenesis of P. gingivalis infection.
