Lactobacillus salivarius UCC118 is a well-characterized and evidence-based probiotic strain. A feeding study led by Fergus Shanahan, MD and his research group at the University College Cork was conducted in patients with ulcerative colitis.
This pilot-scale, open-label study aimed to determine the ability of L. salivarius UCC118 to adhere to human enterocyte epithelial cells. The bacterial strain was administered to patients with ulcerative colitis at ~109 CFU/day for 12 days. Biopsy specimen analyses demonstrated that the ingested bacteria effectively adhered to both inflamed and non-inflamed mucosa of the large bowel in significant numbers and adherence mechanisms were explored.
The results demonstrate the mechanistic evidence for UCC118’s gastrointestinal (GI) transit and adherence to intestinal mucosa.
