Proteins secreted by beneficial gut microbes shown to inhibit salmonella, invasive E. coli

Few treatments exist for bacteria-caused intestinal inflammation that leads to diarrhea, fever and abdominal cramps. But now microbiologists have demonstrated a new approach that may lead to more effective remedies. In a new report, scientists provide the first evidence that small protein molecules called microcins, produced by beneficial gut microbes, play a critical part in blocking certain illness-causing bacteria in inflamed intestines.
