1. Fermentation and Short-Chain Fatty Acid Production:

   • Bacteroides thetaiotaomicron is involved in the fermentation of complex carbohydrates, such as dietary fibers. This process results in the production of short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate. SCFAs have been associated with several health benefits, including the maintenance of gut barrier function and regulation of immune responses.

2. Metabolism of Complex Polysaccharides:

   • B. thetaiotaomicron is known for its ability to break down and metabolize complex polysaccharides present in the diet. This capacity allows the bacterium to extract energy and nutrients from these otherwise indigestible components.

3. Butyrate Production and Gut Health:

   • Butyrate, one of the SCFAs produced by B. thetaiotaomicron, is particularly important for gut health. Butyrate serves as a major energy source for the cells lining the colon, contributes to the maintenance of the colonic epithelium, and has anti-inflammatory effects.

4. Cross-Feeding Interactions:

   • Bacteroides thetaiotaomicron is involved in cross-feeding interactions within the gut microbiota. This involves the exchange of metabolic byproducts between different bacterial species, contributing to the overall stability and functionality of the microbial community.

5. Host-Microbe Interactions:

   • B. thetaiotaomicron can interact with the host's immune system, influencing immune responses in the gut. These interactions are important for the development and regulation of the immune system.

6. Dietary Influence:

   • The abundance and activity of Bacteroides thetaiotaomicron, like other gut bacteria, can be influenced by dietary factors. Diets rich in fiber and complex carbohydrates provide substrates for the fermentation processes carried out by these bacteria.

7. Protection Against Pathogens:

   • B. thetaiotaomicron and other members of the Bacteroides genus are believed to contribute to the protection against pathogenic bacteria by occupying ecological niches and competing for resources in the gut.

Lab Reporting

Different labs use different software to read the sample. See this post for more details.
One lab may say you have none, another may say you have a lot! - This may be solely due to the software they are using to estimate.
We deem lab specific values using values from the KM method for each specific lab to be the most reliable.

Desired Levels Suggestions for Bacteroides thetaiotaomicron

• Lab Low and High are calculated using the formula that most labs use: Mean - 1.95 Standard Deviation to Mean + 1.95 Standard Deviation

These are values that are computed from lab specific samples and are in percentage
