Previous Antibiotic Exposure Reshapes the Population Structure of Infecting Uropathogenic Escherichia coli Strains by Selecting for Antibiotic Resistance over Urovirulence
ABSTRACT Antibiotic therapy is the standard of care for urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC).However, previous antibiotic therapy may impart a selective pressure that influences the population structure tactical pen and pathogenic potential of infecting UPEC strains.Here, we conducted a 3-year study using
