Researchers raised rodents in a sterile environment—meaning the animals are bacteria-free. Then some were inoculated with a probiotic cocktail of human gut bacteria. After that they all got a dose of pathogenic E. coli—the strain behind last year's spinach outbreak. The mice who got the preemptive probiotics never got sick. Their gut bacteria appeared to whisk away the toxins produced by E. coli.
Their probiotic-free counterparts were less lucky. Within a week of being infected with the pathogen they got kidney disease. The researchers presented those findings at a meeting of the American Society for Microbiology, in Denver. [Kathryn A. Eaton et al., Role of the Intestinal Microbiota in Disease Due to Enterohemorrhagic E. coli in Germ Free Mice]
So it’s possible antibiotics could be joined by probiotics as future treatments for bacterial infections. And that you may already be enlisting gut bacteria to fight off E. coli infections. Call it a gut feeling.
