The Australian IBD Microbiome Study seeks to identify people at risk of IBD prior to symptoms through microbiome analysis, preventing symptom progression, and being able to define how patients are likely to respond to treatment.

Study description/purpose

Researchers within the Sydney+ IBD Research Consortia and the Microbiome Research Centre, UNSW are inviting people with Inflammatory Bowel Disease (IBD), their family members and the general population to learn about the changes in the human microbiome.

The Microbiome is the population of microbes occupying various sites within our bodies, and it is already known to play a major roles in diseases such as IBD. If we can understand how the microbiome changes through the course of IBD development and treatment, then we have the potential to positively change health outcomes for future generations.
