The colonization properties of L. rhamnosus GG and LC705 in the human GI tract. A short-term intervention study involving 12 healthy adults assessed the colonization properties of two L. rhamnosus strains in the GI tract. Fecal samples were collected during the intervention (−7 days) and postintervention (0–21 days) periods and analyzed for the presence of strains GG (black) and LC705 (white). The fraction of subjects containing the L. rhamnosus strains above a detection threshold is presented (refer to SI Text for further details.)
