Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study was to investigate the host-microbe interaction effects of various Lacticaseibacillus rhamnosus GG strains, with different binding capacities to the mucus in the small intestine, in healthy individuals

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The project consisted in the supplementation of a) a wild-type LGG strain, b) a low-producing pili LGG strain or c) a high-producing pili LGG strain to study subjects. The individuals received the three treatment combinations in a randomised order. Each supplementation was given to the individuals every 30 min over a period of 6 hours. Eight biopsies from the duodenum were collected at the end of 6 h-solutions administration by flexible gastroduodenoscopy, likewise the routine procedure during this endoscopic investigation. Faecal samples were collected by the study subjects at home 1 day before, 2, 7 and 14 days days after administrations of each oral supplementation. The supplementations were separated by a 3-week wash-out period.
