| Description | Bacteroides ilei is a bacilli-shaped, nonsporulating microbe classified within the extensive Bacteroidetes phylum. This anaerobic organism thrives in the intestinal microflora of animals, where it plays a crucial role in digestive processes. As a chemoheterotroph, B. ilei derives its energy from organic compounds, contributing to the complex microbial ecosystem that aids in the breakdown of dietary nutrients, particularly complex carbohydrates and proteins. B. ilei is considered mesophilic, indicating that it thrives best at moderate temperatures typically found in the digestive tracts of warm-blooded animals. The presence of this bacterium in the gut not only facilitates nutrient absorption but also influences the overall microbial balance, which can impact the host’s health and well-being. The competitive interactions among gut microbiota, including B. ilei, can help inhibit the colonization of pathogenic organisms, thereby functioning as a natural barrier against infections. Interestingly, Bacteroides species, including B. ilei, are known to produce short-chain fatty acids (SCFAs) through the fermentation of dietary fibers. These SCFAs serve not only as an energy source for colonocytes but also play a significant role in modulating immune responses and maintaining gut integrity. Consequently, B. ilei and its relatives are integral to maintaining a healthy gut ecosystem, demonstrating the interconnectedness of microbial populations and host health. |
