Unraveling a Potential Connection Between Bilirubin Metabolism, Gut Microbiota and Inflammatory Bowel Diseases
Unraveling a Potential Connection Between Bilirubin Metabolism, Gut Microbiota and Inflammatory Bowel Diseases
Inflammatory Bowel Diseases (IBDs) are a set of recurrent inflammatory conditions that
 include the colon and small intestine. The two principal conditions include Crohn's disease
 (CD) and ulcerative colitis (UC). The etiology of which is likely to stem from the interplay
 of gut microbial imbalances and host. In this study stool cultures, saliva and skin samples
 will be taken from all participants.
Recent studies have shown that certain CD patients harbor microbial communities that are
 distinct from those of healthy individuals. These studies suggest a central role of the gut
 microbial population in CD. The high complexity of the gut microbiome, which is the most
 densely populated bacterial niche, makes the identification of these bacteria a significant
 challenge. The bacterial population is comprised from 1013 - 1014 individuals, all belonging
 roughly to a thousand different species, mostly anaerobic, and most of them (roughly 70% -
 80%) are uncultivable.

 The goals of this project are to examine a potential link between bilirubin metabolism and
 IBD, by comparing fecal extracts from healthy humans and IBD patients, and to investigate the
 underlying mechanism explaining these differences.
