Prevotella species as oral residents and infectious agents with potential impact on systemic conditions [PDF]
Journal of Oral Microbiology, 2022 Oral Prevotella are known as anaerobic commensals on oral mucosae and in dental plaques from early life onwards, including pigmented P. melaninogenica, P. nigrescens, and P. pallens and non-pigmented Prevotella species. Many Prevotella species contribute

Direct quantitative differentiation between Prevotella intermedia and Prevotella nigrescens in clinical specimens [PDF]
Microbiology, 2002 This paper describes a quantitative fluorescent in situ hybridization (FISH) assay for the differential identification of Prevotella intermedia and Prevotella nigrescens in clinical samples, and compares its performance with less discriminatory culture and quantitative immunofluorescence (IF) assays.

Invasion of Human Cultured Cells by Prevotella Nigrescens [PDF]
International Journal of Immunopathology and Pharmacology, 1999 Invasion of gingival and junctional epithelial cells has been recently proposed as a potentially relevant mechanism in the pathogenesis and recurrence of periodontal disease. The gram negative anaerobe Prevotella nigrescens was shown to be involved in the development of periodontal lesions in man, suggesting a possible involvement of invasivity as a ...

Biochemical and genetic characterization of a Prevotella intermedia/nigrescens-like organism [PDF]
International Journal of Systematic Bacteriology, 1998 Thirty-three previously non-typable faintly pigmented Gram-negative anaerobic bacterial isolates, biochemically most closely related to Prevotella intermedia and Prevotella nigrescens, were analysed for enzymic reactions, cellular fatty acid (CFA) composition, electrophoretic mobility of malate and glutamate dehydrogenases, hybridization with P ...

TLR2 and the NLRP3 inflammasome mediate IL-1β production in Prevotella nigrescens-infected dendritic cells. [PDF]
Int J Med Sci, 2021 Prevotella nigrescens is an oral pathogen that is frequently observed in the subgingival plaque of periodontitis patients. Interleukin-1β (IL-1β) is known to be involved in the immunopathology of periodontal diseases and has been implicated in the ...

In vitro Characterization of Biofilm Formation in Prevotella Species
Frontiers in Oral Health, 2021 Background: Periodontitis, a chronic inflammatory oral infection is the outcome of disturbances in the homeostasis of the oral biofilm microbiota. A number of studies have found the occurrence of Prevotella species in elevated levels in periodontitis ...

Confirmation of the Species Prevotella intermedia and Prevotella nigrescens [PDF]
International Journal of Systematic Bacteriology, 1995 The elevation of the two genotypes of Prevotella intermedia to species rank as P. intermedia and Prevotella nigrescens has increased the need for reliable differentiation between the two taxa. In this study, 53 strains, including strains whose species affiliations were known as well as fresh dental plaque isolates, were subjected to a multilocus enzyme

Frontiers in Microbiology, 2022 Prevotella is recognized as one of the core anaerobic genera in the oral microbiome. In addition, members of this genus belong to microbial communities of the gastrointestinal and respiratory tracts. Several novel Prevotella species, most of them of oral

Identification of a lactoferrin-binding protein in Prevotella nigrescens [PDF]
FEMS Microbiology Letters, 2006 A 40-kDa lactoferrin-binding protein was identified in a strain of Prevotella nigrescens isolated from a patient with periodontitis. The protein was purified by affinity column chromatography using a Sepharose-lactoferrin column and detergent-solubilized membranes.
