Long Term Goal: To generate novel information relating to how the gut microbiota impacts upon clinical disease expression. This information could then be used to build a predictive model designed to optimise diagnosis and therapeutic treatments. This method also holds potential for use as a model for ageing and diseases associated with mitochondria not working properly, such as diabetes, cancer and Parkinson's disease. This research has the potential to reduce costs to the NHS and improve patient care and their quality of life.
