One of our research groups at Nutriepigen has described a new procedure that allows the selective modification of the human intestinal microbiota by using antibodies raised against surface-associated bacterial proteins specific to the microorganism of interest. 

Gut microbiota composition greatly varies among individuals. Some bacterial groups can metabolize dietary polyphenols, such as the ellagitannins occurring in walnuts, pomegranate, strawberries, etc., which are metabolized to the final molecules so-called urolithins (Uros). These metabolites exert in vivo anti-inflammatory, cardioprotective, and neuroprotective activity.
