1. Gut Microbiota Balance: Bacteroides fragilis is considered a key member of the gut microbiota, contributing to the overall balance and diversity of microorganisms in the gut. Its presence helps maintain a healthy microbial community and supports proper gut function.

2. Gut Barrier Function: Bacteroides fragilis plays a role in maintaining gut barrier integrity. It contributes to the regulation of tight junctions between intestinal cells, which helps prevent the entry of harmful substances and pathogens into the bloodstream.

3. Immune System Regulation: Some strains of Bacteroides fragilis have been shown to interact with the immune system, potentially modulating immune responses in the gut. They can promote the development of regulatory T-cells, which help regulate the immune system and maintain immune balance.

4. Short-Chain Fatty Acid Production: While less extensively studied in comparison to other beneficial bacteria, certain strains of Bacteroides fragilis might contribute to short-chain fatty acid (SCFA) production through the fermentation of dietary fibers. SCFAs, such as butyrate, acetate, and propionate, play important roles in gut health.

5. Association with Health Conditions: Alterations in the abundance or diversity of Bacteroides fragilis have been observed in various health conditions, including inflammatory bowel diseases (IBD), obesity, and other metabolic disorders. However, the specific role of Bacteroides fragilis in these conditions is complex and may vary among individuals.

6. Potential Probiotic Properties: Some strains of Bacteroides fragilis have been explored for their potential probiotic properties, aiming to develop probiotic formulations that could support gut health and immune function.

Legend

• The interactions are based on data from 1000 healthy individuals using shotgun 10M reads Precision Biome, a provider in full conformity to EU regulations for health information
• The width of the lines indicates R² (the coefficient of determination)
• Green indicates positive slope
• Red indicates negative
• Interactions are not two way because incidence of each bacteria are different
