Engineering the gut microbiome to optimize warfighter performance

A recent article shows us that American researchers are interested in the intestinal microbiome of war fighters in order to improve their performance on missions. Microbiomes et microbiota The microbiome is the place where a complex set of microorganisms called microbiota develops. In humans, microbiomes from the nose/mouth/throat, skin, lungs, digestive system and vagina are…
