Genomic epidemiology of major extra-intestinal pathogenic Escherichia coli lineages causing urinary tract infections in young women across Canada

Background A few extraintestinal pathogenic Escherichia coli (ExPEC) multilocus sequence types (STs) cause the majority of community-acquired urinary tract infections (UTIs). We examine the genomic epidemiology of major ExPEC lineages, specifically factors associated with intestinal acquisition.
