Carbohydrate consumption drives adaptive mutations in Escherichia coli associated with increased risk for systemic infection

Aaron L. Hecht, Nadim Mahmud, Subhan Chaudhry…·Gary D. Wu

This study shows lactulose consumption selects for E. coli mutations that enhance its metabolic fitness and colonization, increasing infection risk in cirrhosis patients.
