Evolution and function of marsupial gut microbiota

Abstract: 

Despite growing interest in the form and function of mammalian gut microbiomes, few culture-independent studies have focused on the microbiomes of Australian marsupials. In particular, how do the microbiota of the koala and other toxic Eucalypt folivores enable these animals to occupy this specialised dietary niche? We are addressing this question by surveying the gut microbial communities of diprotodont marsupials across a range of phylogeny, diet, and gut morphology. Furthermore, beyond community profiles, we are probing community functionality through metagenome shotgun sequencing of the Vombatiformes (koala and wombat) gut microbiota. Using differential coverage binning and metabolic reconstruction, we have the comparative power to identify specialised pathways in koala and wombat microbiota, from the community-level down to the level of individual population genomes.

Title: 

The healthy human gut microbiota and how chemotherapy and antibiotics affect its composition.

Abstract: 

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.
