Helminths and Intestinal Flora Team Up to Improve Gut Health.

Inflammatory bowel diseases (IBD) are associated with impaired intestinal barrier function, chronic inflammation, and microbial dysbiosis. In a recent publication in Science, Ramanan et al. used murine and human studies to demonstrate that infections with gastrointestinal helminths can protect against IBD by provoking immune responses that alter the balance of commensal and pathogenic bacteria in the intestine.
