‘Scientists studying the body’s natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn).


Scientists know that microbiota—the trillions of beneficial microbes living harmoniously inside our gut—can protect people from bacterial infections, but little is known about how they provide protection. Scientists are studying the microbiota with an eye to finding or enhancing natural treatments to replace antibiotics, which harm microbiota and become less effective as bacteria develop drug resistance.


The study found that taurine given to mice as a supplement in drinking water also prepared the microbiota to prevent infection.’
