Epidemiology of Invasive Escherichia coli Infection and Antibiotic Resistance Status among Patients Treated in U.S. Hospitals: 2009–2016

Published data is limited on the prevalence and risk of recurrence of extraintestinal invasive E. coli infections (IEIs) in the United States.

This real-world study indicates a substantial burden of IEI and recurrent IEI exists in the Unites States as well as increasing resistance to ESC4. Future research should explore risk factors of recurrent IEI aiming to effectively prevent such infections.
