Complete Survival when lethal Bacteria are fed rather than killed (Proof of Concept )

Researchers report that giving mice dietary iron supplements enabled them to survive a normally lethal bacterial infection and resulted in later generations of those bacteria being less virulent. The approach demonstrates in preclinical studies that non-antibiotic-based strategies — such as nutritional interventions — can shift the relationship between the patient and pathogens away from antagonism and toward cooperation.
