Probiotic offers protection against intestinal damage

There is a critical unmet need to help tighten and maintain a healthy intestinal barrier and treat a leaky gut. Researchers have now found that a unique strain of probiotic bacteria, Bifidobacterium bifidum BB1, enhances intestinal barrier function and protects against penetration of bacteria and various harmful agents in the intestine. The findings, detailed in an article in The American Journal of Pathology, published by Elsevier, can help advance the development of novel, targeted, naturally occurring probiotic therapy for patients with inflammatory bowel disease (IBD) and other inflammatory diseases, such as fatty liver disease or alcoholic liver disease, that are associated with a leaky or disordered intestinal barrier.
