Prevotella nigrescens ATCC 33563

Prevotella nigrescens ATCC 33563 is a Gram-negative, anaerobic bacterium that exhibits the presence of flagella. This organism is part of the Prevotella genus, which is known for its role in the human microbiome, particularly in the oral cavity and gastrointestinal tract. The anaerobic nature of P. nigrescens suggests that it thrives in oxygen-deprived environments, which is typical for many members of the Prevotella species. P. nigrescens ATCC 33563 has a single replicon, indicating a relatively simple genomic structure compared to organisms with multiple replicons. The specific accession number for the genomic data of this strain is AFPX00000000.1, which can be used to reference its genetic information in various biological databases. The ecological significance of Prevotella nigrescens lies in its contribution to the overall microbial community within the host. As an anaerobe, it plays a crucial role in the fermentation of dietary fibers and the metabolism of complex carbohydrates, which can influence host health and disease states, including oral health and systemic conditions. The presence of flagella may also provide motility advantages, aiding this bacterium in colonizing specific niches within the anaerobic environments it inhabits. Overall, P. nigrescens ATCC 33563 represents an important component of the microbial ecosystem with potential implications for human health.
