Microbial Immunomodulatory Function is Altered in Inflammatory Bowel Disease Independent of Microbial Composition

Rabina Giri, Jing Jie Teh, F Zhang…·Jakob Begun

This study shows that the microbiome in IBD patients has increased pro-inflammatory activity, even when microbial composition is similar to non-IBD controls.

Long-term iron deficiency and iron supplementation exacerbate acute DSS-induced colitis and are associated with significant dysbiosis

Awad Mahalhal, Michael D. Burkitt, Carrie A. Duckworth…·Chris S. Probert

This study shows that long-term iron deficiency and supplementation affect gut microbiota but not chronic colitis, while exacerbating acute DSS-induced colitis.
