The same serotype is also frequently isolated from the extraintestinal lesions of colibacillosis in poultry, but it is not well known to what extent human and avian strains of this particular serotype are related. Twenty-two ExPEC isolates of human origin and 33 isolates of avian origin were compared on the basis of their virulence determinants, lethality for chicks, pulsed-field gel electrophoresis (PFGE) patterns, and classification in the main phylogenetic groups. Both avian and human isolates were lethal for chicks and harbored similar virulence genotypes. A major virulence pattern, identified in 75% of the isolates, was characterized by the presence of F1 variant fimbriae; S fimbriae; IbeA; the aerobactin system; and genomic fragments A9, A12, D1, D7, D10, and D11 and by the absence of P fimbriae, F1C fimbriae, Afa adhesin, and CNF1. All but one of the avian and human isolates also belonged to major phylogenetic group B2. However, various subclonal populations could be distinguished by PFGE in relation to animal species and geographical origin. These results demonstrate that very closely related clones can be recovered from extraintestinal infections in humans and chickens and suggest that avian pathogenic\n            <jats:italic>E. coli<\/jats:italic>\n            isolates of serotype O18:K1:H7 are potential human pathogens.\n          <\/jats:p>","DOI":"10.1128\/jcm.00548-06","type":"journal-article","created":{"date-parts":[[2006,10,4]],"date-time":"2006-10-04T17:59:53Z","timestamp":1159984793000},"page":"3484-3492","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":148,"title":["Common Virulence Factors and Genetic Relationships between O18:K1:H7\n            <i>Escherichia coli<\/i>\n            Isolates of Human and Avian Origin"],"prefix":"10.1128","volume":"44","author":[{"given":"Maryvonne","family":"Moulin-Schouleur","sequence":"first","affiliation":[{"name":"INRA, Centre de Tours, UR1282, 37380 Nouzilly, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Schouler","sequence":"additional","affiliation":[{"name":"INRA, Centre de Tours, UR1282, 37380 Nouzilly, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Tailliez","sequence":"additional","affiliation":[{"name":"INRA, Unite\u0301 d'Ecologie Microbienne des Insectes et Interactions Ho\u0302te-Pathoge\u0300ne, UMR1133, Universite\u0301 Montpellier II, 34095 Montpellier cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mu-Rong","family":"Kao","sequence":"additional","affiliation":[{"name":"INRA, Centre de Tours, UR1282, 37380 Nouzilly, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annie","family":"Bre\u0301e","sequence":"additional","affiliation":[{"name":"INRA, Centre de Tours, UR1282, 37380 Nouzilly, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Germon","sequence":"additional","affiliation":[{"name":"INRA, Centre de Tours, UR1282, 37380 Nouzilly, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Oswald","sequence":"additional","affiliation":[{"name":"UMR1225, INRA-ENVT, 23 chemin des Capelles, 31076 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Mainil","sequence":"additional","affiliation":[{"name":"Universite\u0301 de Lie\u0300ge, Faculte\u0301 de Me\u0301decine Ve\u0301te\u0301rinaire, De\u0301partement des Maladies Infectieuses et Parasitaires, Sart Tilman, 4000 Lie\u0300ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Blanco","sequence":"additional","affiliation":[{"name":"Laboratorio de Referencia de E. coli (LERC), Departamento de Microbioloxi\u0301a e Parasitoloxi\u0301a, Facultade de Veterinaria, Universidade de Santiago de Compostela, 22002 Lugo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Blanco","sequence":"additional","affiliation":[{"name":"Laboratorio de Referencia de E. coli (LERC), Departamento de Microbioloxi\u0301a e Parasitoloxi\u0301a, Facultade de Veterinaria, Universidade de Santiago de Compostela, 22002 Lugo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/iai.51.1.268-276.1986"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/iai.39.1.315-335.1983"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.2307\/1592549"},{"key":"e_1_3_2_5_2","first-page":"631","year":"2003","unstructured":"Barnes, H.
