“Good” and “bad” gut bacteria – the notion of how much both influence human health has marked a new era of Microbiology.
The intestine gives home to trillions of friendly bacteria and battles disease-causing bacteria. The intestinal immune system reacts to all species that inhabit us. Millions of years of co-evolution formed it to become a learning bio-containment system that allows the disease-free coexistence with the broadest possible diversity of microbes. Our human-microbial health depends on it.
Our beneficial bacterial “partners” and disease-causing pathogens require entirely different treatments. We would like to better understand which bacterial features and behaviors tell the immune system what to do.
