The healthy human gut microbiota and how chemotherapy and antibiotics affect its composition.
Recent science associates the gut microbiota composition with the development of complex diseases such as for example cardio-vascular diseases, diabetes and inflammatory bowel diseases. Now, the human gastro-intestinal microbiota must be understood as a microbial organ whose metabolism provides essential functions to the host rather than just supplementary nutrient acquisition.
The first aim of this talk is to discuss what makes a “healthy” gut microbiota together with results from analysing vegetarian and elderly gut microbiota.
The second aim will be to discuss results from analysing the gut microbiota of people undergoing chemotherapy and antibiotics.
Whether (and how) diet and age affect the gut microbiota composition is not only really interesting; knowing the diversity of healthy gut microbiotas may help us to decide which composition to restore a perturbed microbiota to, for example after chemotherapy and antibiotic treatment.
