The Epidemic of Extended-Spectrum-β-Lactamase-Producing Escherichia coli ST131 Is Driven by a Single Highly Pathogenic Subclone, H30-Rx

Johnston,Veronika Tchesnokova,Lora Nordstrom,Maria Billig,Sujay Chattopadhyay,Marc Stegger,Marc Stegger,Paal Skytt Andersen,Paal Skytt Andersen,Talima Pearson,Kim Riddell,Peggy Rogers,Delia Scholes,Barbara C.

TL;DR: P pulsed-field gel electrophoresis and whole-genome sequencing are applied to reconstruct the evolutionary history of the ST131 clone and suggest that the high prevalence of CTX-M-15 production among ST131 isolates is due primarily to the expansion of a single, highly virulent subclone, H30-Rx.
Journal ArticleDOI

TL;DR: Most current fluoroquinolone-resistant E. coli clinical isolates represent a highly clonal subgroup that likely originated from a single rapidly expanded and disseminated ST131 strain, which expanded abruptly after 2000.
Journal ArticleDOI
High-resolution two-locus clonal typing of extraintestinal pathogenic Escherichia coli.

TL;DR: This work describes a two-locus, sequence-based typing scheme for Escherichia coli that utilizes a 489-nucleotide (nt) internal fragment of fimH (encoding the type 1 fimbrial adhesin) and the 469-nt internal fumC fragment used in standard MLST.
Journal ArticleDOI

TL;DR: In E. coli, subspecies-level identification by clonotyping can be used to significantly improve empirical predictions of antimicrobial susceptibility and clinical outcomes in a timely manner.
