Microbiota influences immune maturation
Реальна сканувальна електронна мікрофотографія E. coli, NIAID; контекст бактерій, не зразок мишачої мікробіоти досліду / Actual NIAID scanning electron micrograph of E. coli; bacterial context, not a mouse-microbiota sample from the study.

Microbiota interacts with the immune system, but “without microbes every harmless bacterium becomes lethal” is too absolute. Germ-free mouse experiments showed altered intestinal immune maturation and dependence on the colonizing microbiota. This is evidence from a defined animal model, rather than a direct experiment on humans in a sterile world or advice to acquire infections deliberately.
