Gut Bacteria May Hold Key to Peanut Allergy Severity
20 Jul
Summary
- Certain mouth and gut bacteria may influence peanut allergy reactions.
- Rothia bacteria species can break down peanut allergens.
- More allergen-degrading bacteria correlate with higher peanut tolerance.
The severity of peanut allergies may be significantly influenced by the microbial communities residing in the mouth and gut, according to new research published in Cell Host & Microbe. Scientists identified that certain bacteria can degrade components of peanuts, potentially modulating allergic responses.
Researchers found that species of Rothia bacteria were particularly adept at breaking down major peanut allergens. Individuals with a higher abundance of these bacteria showed a greater tolerance for peanuts, as fewer allergens reached the bloodstream to trigger immune reactions. This pathway links the oral and gut microbiome to food allergies.
The study validated these findings in children, demonstrating a correlation between peanut tolerance and the presence of Rothia. These insights could pave the way for novel prevention and treatment strategies, such as probiotic therapies and oral immunotherapies.
