The aim of this study was to characterize the clonal structure, extended-spectrum \u03b2-lactamases (ESBLs), and acquired AmpC-like cephalosporinases in the\n            <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">Escherichia coli<\/jats:named-content>\n            populations collected. A total of 376 isolates were randomly selected. The overall number of sequence types (STs) was 76, including 7 STs that grouped at least 10 isolates from at least three centers each, namely, STs 10, 38, 69, 131, 405, 410, and 648. These clones comprised 65.2% of all isolates, and ST131 alone comprised 41.2%. Of 54 STs observed only in one center, some STs played a locally significant role, like ST156 and ST393 in GI or ST372 and ST398 in TA. Among 16 new STs, five arose from evolution within the ST10 and ST131 clonal complexes. ESBLs and AmpCs accounted for 94.7% and 5.6% of the ESC-hydrolyzing \u03b2-lactamases, respectively, being dominated by the CTX-M-like enzymes (79.9%), followed by the SHV (13.5%) and CMY-2 (5.3%) types. CTX-M-15 was the most prevalent \u03b2-lactamase overall (40.6%); other ubiquitous enzymes were CTX-M-14 and CMY-2. Almost none of the common clones correlated strictly with one \u03b2-lactamase; although 58.7% of ST131 isolates produced CTX-M-15, the clone also expressed nine other enzymes. A number of clone variants with specific pulsed-field gel electrophoresis and ESBL types were spread in some locales, potentially representing newly emerging\n            <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">E. coli<\/jats:named-content>\n            epidemic strains.\n          <\/jats:p>","DOI":"10.1128\/aac.01656-12","type":"journal-article","created":{"date-parts":[[2012,11,1]],"date-time":"2012-11-01T00:17:28Z","timestamp":1351729048000},"page":"309-316","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":59,"title":["Clonal Structure, Extended-Spectrum \u03b2-Lactamases, and Acquired AmpC-Type Cephalosporinases of Escherichia coli Populations Colonizing Patients in Rehabilitation Centers in Four Countries"],"prefix":"10.1128","volume":"57","author":[{"given":"R.","family":"Izdebski","sequence":"first","affiliation":[{"name":"National Medicines Institute, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Baraniak","sequence":"additional","affiliation":[{"name":"National Medicines Institute, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Fiett","sequence":"additional","affiliation":[{"name":"National Medicines Institute, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Adler","sequence":"additional","affiliation":[{"name":"Division of Epidemiology and Preventive Medicine, Tel-Aviv Sourasky Medical Center, Tel-Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Kazma","sequence":"additional","affiliation":[{"name":"Division of Epidemiology and Preventive Medicine, Tel-Aviv Sourasky Medical Center, Tel-Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Salomon","sequence":"additional","affiliation":[{"name":"INSERM, Institut Pasteur, CNAM, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Lawrence","sequence":"additional","affiliation":[{"name":"Groupe Hospitalier Universitaire Paris Ile-de-France Ouest, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Rossini","sequence":"additional","affiliation":[{"name":"Fondazione Santa Lucia IRCCS, Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Salvia","sequence":"additional","affiliation":[{"name":"Fondazione Santa Lucia IRCCS, Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Vidal Samso","sequence":"additional","affiliation":[{"name":"Institute Guttmann, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Fierro","sequence":"additional","affiliation":[{"name":"Institute Guttmann, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Paul","sequence":"additional","affiliation":[{"name":"Loewenstein Hospital, Ra'anana, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"Lerman","sequence":"additional","affiliation":[{"name":"Geriatric Division, Tel-Aviv Sourasky Medical Center, Tel-Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Malhotra-Kumar","sequence":"additional","affiliation":[{"name":"University of Antwerp, Antwerp, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Lammens","sequence":"additional","affiliation":[{"name":"University of Antwerp, Antwerp, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Goossens","sequence":"additional","affiliation":[{"name":"University of Antwerp, Antwerp, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.","family":"Hryniewicz","sequence":"additional","affiliation":[{"name":"National Medicines Institute, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Brun-Buisson","sequence":"additional","affiliation":[{"name":"INSERM, U957, and Universit\u00e9 Paris-Est, Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"Carmeli","sequence":"additional","affiliation":[{"name":"Division of Epidemiology and Preventive Medicine, Tel-Aviv Sourasky Medical Center, Tel-Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Gniadkowski","sequence":"additional","affiliation":[{"name":"National Medicines Institute, Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","first-page":"2189","volume-title":"Infectious diseases","author":"Rozenberg-Arska M","year":"2004","unstructured":"Rozenberg-ArskaM VisserMR. 2004.
