| Description | Prevotella buccalis is a Gram-negative, rod-shaped bacterium that thrives in a range of temperatures, specifically in the mesophilic category (20-45°C). This microbe is a heterotroph, utilizing organic compounds as its energy source, and is able to produce energy through fermentation. As a result, it does not require oxygen for its metabolic processes. P. buccalis can be found on various human body sites, including the oral cavity, where it inhibits the biofilm of dental plaque, and the gastrointestinal tract, where it contributes to the breakdown of complex carbohydrates. Its ability to thrive in different environments enables it to colonize a wide range of body sites in all possible species, including humans, animals, and even plants. Furthermore, P. buccalis is an obligate anaerobe, meaning it is unable to tolerate oxygen and is inactivated in the presence of even low levels of oxygen. This adaptation allows it to thrive in environments with limited oxygen availability, such as the human gut, where it plays a crucial role in the decomposition of organic matter. In terms of its ecological importance, P. buccalis is a key player in the human microbiome, influencing the development of dental caries and periodontal disease. Its ability to break down complex carbohydrates also enables it to contribute to the production of short-chain fatty acids, which are important energy sources for the host. Despite its importance in the human microbiome, P. buccalis has also been linked to several diseases, including diabetes, cardiovascular disease, and even obesity. Further research is needed to fully understand the complex interactions between P. buccalis and its human host, as well as its role in various diseases. |
