Prevotella

(prev'ō-tel'ă),
Genus of gram-negative, nonmotile, non-spore-forming, obligately anaerobic, chemoorganotrophic, and pleomorphic rods; contains many species previously classified in the genus Bacteroides. P. melaninogenica is the type species.

LPS from gram-negative bacteria such as Prevotella and Porphyromonas isolated from the oral cavity are able to produce classic manifestations that are less damaging to host tissues than those from E.
The significant negative SpCC showed between OTUs was related to Fusobacteria, Treponema, Bacillus, and Prevotella genera.
Prevotella species are anaerobic Gram-negative bacteria of the Bacteroidetes phylum that were found to be greater in CRC patients than in stool from cancer-free patients [87].
The number of Prevotella in IBS-D patients was over 100-fold higher when compared with healthy subjects (p < 0.05) (Figure 2).
Prevotella flourishes if you eat a plant-based diet - lots of fruit, vegetables, leafy greens seeds, nuts, beans and lentils.
Two species belonged to the Bacteroidetes phylum, one of those being Prevotella copri.
The following species were also eliminated: Bacteroides uniformis and Parabacteroides distasonis classified as Gram(-) anaerobes; Acinetobacter freundii, Burkholderia cepacia, and Neisseria sicca (Gram(-) aerobe), as well as Staphylococcus epidermidis MSCNS (Gram(+) aerobe), which can cause opportunistic infections, including sepsis.The microflora gained the following species, Gram(+) anaerobes: Atopobium minutum and Clostridium butyricum, Gram(-) anaerobes: Capnocytophaga ochracea and Prevotella melaninogenica, Gram(+) aerobes: Microccus spp.
The phylum Bacteroidetes is mainly comprised by two genera, Bacteroides and Prevotella. The genus Bacteroides fragilis plays an important role in mucosal T-cell homeostasis through regulating the function of T-cell [24].
Strongly correlating to long-term diet [24], different enterotypes can also be identified through a variation in the levels of one of the three most abundant genera: Bacteroides (enterotype 1), Prevotella (enterotype 2), and Ruminococcus (enterotype 3), which is often less clearly distinguished [25].
[17], includes known periodontal pathogens such as Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia, Eikenella corrodens, and Eubacterium nodatum; Gram-positive bacteria such as Streptococcus sanguis, mutants, mitis, and salivarius; and other Gram-negative anaerobic bacteria such as Campylobacter rectus.
Findings supporting the idea that the onset of autoimmunity may be related to gastrointestinal tract are as follows: (1) microbial composition in subjects with early rheumatoid arthritis differs to controls, with a reduction of certain bacteria belonging to the family Bifidobacterium and Bacteroides [15, 16], and a marked increase of species belonging to the genus Prevotella [17].
