Epidemiology and Antimicrobial Resistance Characteristics of the Sequence Type 131-H30 Subclone Among Extraintestinal Escherichia coli Collected From US Children

Escherichia coli sequence type (ST) 131-H30 is a globally important pathogen implicated in rising rates of multidrug resistance among E. coli causing extraintestinal infections. Previous studies have focused on adults, leaving the epidemiology of H30 among children undefined. We used clinical data and isolates from a case-control study of extended-spectrum cephalosporin-resistant E. coli conducted at 4 US children’s hospitals to estimate the...
