SUMMARY Extraintestinal pathogenic Escherichia coli (ExPEC) strains are responsible for a
majority of human extraintestinal infections globally, resulting in enormous direct medical …

Bacterial antimicrobial resistance (AMR) is constantly evolving and horizontal gene transfer
through plasmids plays a major role. The identification of plasmid characteristics and their …

Globally, rates of ESBL-producing Enterobacteriaceae are rising. We undertook a literature
review, and present the temporal trends in bla CTX-M epidemiology, showing that bla CTX …

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 …

Escherichia coli sequence type 131 (ST131) has emerged globally as the most predominant
extraintestinal pathogenic lineage within this clinically important species, and its association …

Escherichia coli represents an incredible versatile and diverse enterobacterial species and
can be subdivided into the following;(i) intestinal non-pathogenic, commensal isolates.(ii) …

CTX-M enzymes, the plasmid-mediated cefotaximases, constitute a rapidly growing family of
extended-spectrum β-lactamases (ESBLs) with significant clinical impact. CTX-Ms are found …

Escherichia coli remains one of the most frequent causes of nosocomial and community-
acquired bacterial infections including urinary tract infections, enteric infections and systemic …

β-lactam antibiotics are one of the most widely used and diverse classes of antimicrobial
agents for treating both Gram-negative and Gram-positive bacterial infections. The β-lactam …

Abstract Objectives In 2006, 0.6% of healthy subjects living in the Paris area had extended-
spectrum β-lactamase (ESBL)-producing Escherichia coli in their gut. To assess the …
