Prevotella species may be commensal in the vagina, though increased abundance of Prevotella in vaginal mucosa is associated with bacterial vaginosis.A study of 542 Korean women, including identical and fraternal twins, highlighted that the vaginal microbiota's composition is influenced by menopausal status and bacterial vaginosis, with Lactobacillus and Prevotella being the most inheritable ...
As of January 2024 Prevotellaceae is split into 10 valid genera: Alloprevotella, Hallella, Hoylesella, Leyella, Palleniella, Paraprevotella, Prevotella, Pseudoprevotella, Segatella, Xylanibacter. [5] These 10 genera include 69 different bacterial species. The genus Prevotella is known for its role in the human gastrointestinal microbiota.
Prevotella bivia is a species of bacteria in the genus Prevotella.It is gram-negative.It is one cause of pelvic inflammatory disease. [1]Other Prevotella spp. are members of the oral and vaginal microbiota, and are recovered from anaerobic infections of the respiratory tract.
Pigmented Prevotella and Porphyromonas spp. are especially common in bite and skull bone infections, whereas members of the B. fragilis group are often found in vascular disease or neuropathy. Fusobacterium spp., which belongs to the oral microflora, are most often isolated from bites and from cranial and facial bone infections.
Prevotella intermedia (formerly Bacteroides intermedius) is a gram-negative, obligate anaerobic pathogenic bacterium involved in periodontal infections, including gingivitis and periodontitis, and often found in acute necrotizing ulcerative gingivitis. It is commonly isolated from dental abscesses, where obligate anaerobes predominate.
The Affirm VPIII test may be used for the rapid diagnosis of BV in symptomatic women but uses expensive proprietary equipment to read results, and does not detect other pathogens that cause BV, including Prevotella spp, Bacteroides spp, and Mobiluncus spp. [52] The cervicovaginal microbiome measured using 16S rRNA sequencing has the capacity to ...

Prevotella nigrescens is a species of bacterium. [1] Prevotella nigrescens has a gram negative gram stain. When P. nigrescens microflora colonize they trigger an over-aggressive response from the immune system and increase the incidence of many diseases and infections. One specific type of bacteria that is part of the normal oral flora but ...
