Prevotella Phylogeny: Genomic And Molecular Insights Into The Role Of The Human Commensal Prevotella In Cystic Fibrosis
The genus Prevotella comprises of a diverse set of gram-negative anaerobes that are implicated in both health and disease. Prevotella is a common human commensal of various anatomic sites but can also be associated with the dysbiotic microbiomes of various chronic inflammatory diseases. Due to it’s …

The Role of Gram - Negative Anaerobes in Hidradenitis Suppurativa
… Gram-negative anaerobic bacteria (GNA) such as Prevotella, Porphyromonas, and Fusobacterium are commonly identified in HS lesions, and their prevalence in lesions is associated with HS disease severity. Additionally, newly epithelialized structures called "dermal tunnels" are found in severe …

DNA-DNA Checkerboard Hybridization to Identify Bacteria in Human Plaque Samples
… or very difficult to grow, such as<em> Prevotella intermedia, P. nigrescens</em>, and <em>Eubacterium brachy</em>. Digoxygenin probes were prepared for 15 oral bacteria. These probes were used with a checkerboard DNA-DNA hybridization scheme to analyze whether human plaque samples …

Proteomic comparison of Amoxicillin resistant and susceptible periodontal Provotella Intermedia and Provotella Nigrescens clinical isolation with Matrix-Assisted Laser Disportion Ionization Time-Of-/flight mass spectrometry
Objectives: Prevotella intermedia and Prevotella nigrescens are dark-pigmented, non-motile, anaerobic rods regarded as important bacterial pathogens in the etiology and progression of human chronic periodontitis. Because the bacterial species may not be adequately suppressed in the subgingival …
