Beware probiotics in ICU patients

A collaborative study published in Nature Medicine sounds a note of caution in using probiotics in the ICU. In a small percentage of cases, the live bacteria in the probiotic formulations can cause bloodstream infections. An investigation began when the Infection Prevention and Control group at Boston Children's Hospital began noticing cases of bacteremia in the ICU caused by Lactobacillus, a genus of bacteria commonly found in probiotics.
