Incidence of Antibiotic-Resistant Escherichia coli Bacteriuria According to Age and Location of Onset: A Population-Based Study From Olmsted County, Minnesota

In this population-based study, the incidence of antibiotic-resistant E coli bacteriuria nearly doubled during the 5-year study period among elderly patients and those with community-associated isolates. These patient groups should be targets of interventions to slow the emergence and spread of antibiotic-resistant E coli.
