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 ...
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 ...
The genus Prevotella is known for its role in the human gastrointestinal microbiota. Prevotella species are among the most numerous microbes culturable from the rumen and hind gut of cattle and sheep, where they help the breakdown of protein and carbohydrate foods. They are also present in humans, where they can be opportunistic pathogens.

In the United States, florfenicol is indicated for the treatment of bovine respiratory disease (BRD) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni, for treatment of bovine interdigital phlegmon (foot rot, acute interdigital necrobacillosis, infectious pododermatitis) associated with Fusobacterium necrophorum and Prevotella melaninogenica.
Pre-exposure prophylaxis (PrEP), is the use of medications to prevent the spread of disease in people who have not yet been exposed to a disease-causing agent. Vaccination is the most commonly used form of pre-exposure prophylaxis; other forms of pre-exposure prophylaxis generally involve drug treatment, known as chemoprophylaxis.
While Verticillium spp. are very diverse, the basic life cycle of the pathogen is similar across species, except in their survival structures. The survival structures vary by species with V. albo-atrum forming mycelium, V. dahliae forming microsclerotia, V. nigrescens and V. nubilum forming chlamydospores, and V. tricorpus forming all three.
