Rapid detection of the O25b-ST131 clone of Escherichia coli encompassing the CTX-M-15-producing strains.
OBJECTIVES Recently, a CTX-M-15 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli O25b-ST131 clone, belonging to the B2 phylogenetic group and with a high virulence potential, has been reported all over the world, representing a major public health problem. The present study was carried out to develop a rapid and simple detection assay that identifies members of this clone. M...
متن کاملIntercontinental emergence of Escherichia coli clone O25:H4-ST131 producing CTX-M-15.
BACKGROUND Concomitant with the recent emergence of CTX-M-type extended-spectrum beta-lactamases (ESBLs), Escherichia coli has become the enterobacterial species most affected by ESBLs. Multiple locales are encountering CTX-M-positive E. coli, including specifically CTX-M-15. To gain insights into the mechanism underlying this phenomenon, we assessed clonality and diversity of virulence profile...
متن کاملThe CTX-M-15-Producing Escherichia coli Clone O25b: H4-ST131 Has High Intestine Colonization and Urinary Tract Infection Abilities
Increasing numbers of pyelonephritis-associated uropathogenic Escherichia coli (UPEC) are exhibiting high resistance to antibiotic therapy. They include a particular clonal group, the CTX-M-15-producing O25b:H4-ST131 clone, which has been shown to have a high dissemination potential. Here we show that a representative isolate of this E. coli clone, referred to as TN03, has enhanced metabolic ca...
متن کاملDissemination of Clonally Related Escherichia coli Strains Expressing Extended-Spectrum β-Lactamase CTX-M-15
We analyzed 43 CTX-M-15-producing Escherichia coli isolates and 6 plasmids encoding the blaCTX-M-15 gene from Canada, India, Kuwait, France, Switzerland, Portugal, and Spain. Most isolates belonged to phylogroups B2 (50%) and D (25%). An EC-B2 strain of clonal complex sequence type (ST) 131 was detected in all countries; other B2 isolates corresponded to ST28, ST405, ST354, and ST695 from speci...
متن کاملTurkey: a further country concerned by community-acquired Escherichia coli clone O25-ST131 producing CTX-M-15.
OBJECTIVES The aim of this study was to assess the frequency and diversity of extended-spectrum beta-lactamases (ESBLs) produced by exclusively community-acquired Escherichia coli isolates in Izmir (Turkey) and to search for isolates producing CTX-M-15 and belonging to the pandemic clone E. coli O25-ST131. METHODS The patients with E. coli urinary tract infections (UTIs) and no hospitalizatio...
