Intercontinental 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 کاملRapid 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 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 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...
متن کاملCTX-M-15-producing Escherichia coli clone B2-O25b-ST131 and Klebsiella spp. isolates in municipal wastewater treatment plant effluents.
OBJECTIVES The global occurrence of antibiotic resistance genes in bacteria in water environments is an increasing concern. Treated wastewater was sampled daily over a 45 day period from the outflow of a municipal wastewater treatment plant in Brno, Czech Republic, and examined for extended-spectrum β-lactamase (ESBL)-producing bacteria. METHODS Water samples were cultivated on MacConkey agar...
