Microbial Ecology of Health. Coordinator: Brigidi

Understanding the role of the human intestinal microbiota in our physiology and evolutionary history is the main mission of the research group. The study of the animal microbiota and plant-associated microbial communities are other research lines.

The Human Superorganism

Human beings have been reconsidered as superorganisms in co-evolution with their microbial communities. Ten to 100 trillion microbes inhabit our gastrointestinal tract, constituting the gut microbiota. Their collective genome (microbiome) is estimated to contain >150 times as many genes as the human genome, and encodes functions we have not evolved on our own.

Through an extensive microbial-host crosstalk, the gut microbiota strongly influences our physiology and metabolic phenotype. In addition to increasing energy harvest from ingested food and providing vitamins, the microbiota improves the barrier function, is critical to the development and functionality of our immune system, and modulates the endocrine and central nervous system.

Plant Microbiota

Plant-associated microbial communities are critical to several ecological and biogeochemical processes, such as mineral uptake, pathogen protection, phytoremediation, etc., with ultimate repercussions on agriculture sustainability and environment.

Animal Microbiota

Like humans, animals host vast microbial communities. Exploring their microbiota allows us to assess ecological and evolutionary interactions, and better understand human physiology.
