| Description | Prevotella nanceiensis is a Gram-negative, rod-shaped bacterium that thrives in anaerobic environments, classifying it as an obligate anaerobe. It is typically found in the human oral cavity, gastrointestinal tract, and female reproductive tract, reflecting its role as a commensal microbe in various body sites. As a chemoheterotroph, it derives energy from organic compounds, which it metabolizes through fermentation processes under low-oxygen conditions. The Gram-negative staining of Prevotella nanceiensis indicates the presence of a thin peptidoglycan layer surrounded by an outer membrane, which is characteristic of this bacterial group. This structural feature not only protects the microbe from environmental stressors but also contributes to its pathogenicity. The rod shape facilitates motility and colonization, allowing it to thrive in its preferred anaerobic niches. Prevotella nanceiensis has been associated with various health conditions, particularly in the context of periodontal disease and other inflammatory conditions. Its ability to metabolize a diverse range of carbohydrates supports its role in the intricate microbial communities found in human biofilms. By contributing to the balance of the gut microbiota, it may aid digestion and nutrient absorption. Furthermore, this bacterium has been the subject of research due to its potential involvement in interactions with other microbial species and its influence on host immune responses. Studies have suggested that an imbalance in Prevotella species may be linked to obesity and metabolic syndrome, highlighting the intricate relationships between our microbiome and overall health. |
