Saliva's Hidden Shield: Rothia aeria Could Neutralize Peanut Allergens
Researchers found bacteria common to the mouth and gut, especially Rothia aeria, can degrade peanut allergen proteins Ara h 1 and Ara h 2 in lab tests, markedly reducing allergenicity in vitro and correlating higher Rothia aeria with non-allergic or tolerant individuals; this points to potential probiotic or adjunct oral immunotherapy approaches for peanut allergy, with further work in animals and humans.
