In 2008, a previously unknown Escherichia coli clonal group, sequence type 131 (ST131),
was identified on three continents. Today, ST131 is the predominant E. coli lineage among …

Multilocus sequence typing reveals that many bacterial species have a clonal structure and
that some clones are widespread. This underlying phylogeny was not revealed by pulsed …

Pathogenic Escherichia coli strains cause a wide variety of intestinal and extraintestinal
infections. The widespread geographical clonal dissemination of intestinal pathogenic E …

Escherichia coli sequence type 131 (ST131) is a worldwide pandemic clone, causing
predominantly community-onset antimicrobial-resistant infection. Its pandemic spread was …

Bladder infections affect millions of people yearly, and recurrent symptomatic infections
(cystitis) are very common. The rapid increase in infections caused by multidrug-resistant …

Background. Escherichia coli sequence type ST131 (O25: H4), associated with the CTX-M-
15 extended-spectrum β-lactamase, has emerged internationally as a multidrug-resistant …

Escherichia coli is one of the most well-adapted and pathogenically versatile bacterial
organisms. It causes a variety of human infections, including gastrointestinal illnesses and …

Escherichia coli sequence type 131 (ST131) is an extensively antimicrobial-resistant E. coli
clonal group that has spread explosively throughout the world. Recent molecular …

The ongoing global spread and increased prevalence of CTX-M-type extended-spectrum β-
lactamases in Enterobacteriaceae is of great concern. The successful distribution of CTX-M …

Escherichia coli strains causing urinary tract infection (UTI) are increasingly recognized as
belonging to specific clones. E. coli clone O25b: H4-ST131 has recently emerged globally …
