In this study, the phenotype, genotype and the phylogeny of UPEC strains isolated from the urine of pediatric female patients with cystitis of normal and abnormal urinary tract were determined. Multiplex PCR results demonstrated that 86% of the strains isolated from female patients with normal urinary tract (NUT), belonged to the phylo-groups B2 and D. Their prevalence decreased to 23% in strains isolated from patients with abnormal urinary tract (AUT). More of the isolates from AUT patients produced a biofilm on polystyrene and polyvinyl chloride (PVC), adhered to epithelial cells, and encoded pap and sfa genes than strains isolated from female patients with NUT. In contrast, a higher number of hemolysin-producing strains with serogroups associated with UPEC were isolated from patients with NUT. In summary, the results suggest that cystitis in female patients with NUT is associated with ExPEC, whereas cystitis in female patients with AUT is associated with pathogenic intestinal E. coli strains that have acquired the ability to colonize the bladder.<\/jats:p>","DOI":"10.3390\/pathogens11020231","type":"journal-article","created":{"date-parts":[[2022,2,11]],"date-time":"2022-02-11T02:35:51Z","timestamp":1644546951000},"page":"231","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Escherichia coli Strains Responsible for Cystitis in Female Pediatric Patients with Normal and Abnormal Urinary Tracts Have Different Virulence Profiles"],"prefix":"10.3390","volume":"11","author":[{"given":"Marta","family":"Domingos","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvio","family":"da Silva Junior","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wagner","family":"Milanello","sequence":"additional","affiliation":[{"name":"Hospital Infantil Darcy Vargas, Rua Ser\u00e1fico de Assis Carvalho, 34, S\u00e3o Paulo 05614-040, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shirley","family":"Nakano","sequence":"additional","affiliation":[{"name":"Hospital Infantil Darcy Vargas, Rua Ser\u00e1fico de Assis Carvalho, 34, S\u00e3o Paulo 05614-040, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0654-639X","authenticated-orcid":false,"given":"Marcia","family":"Franzolin","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6158-5247","authenticated-orcid":false,"given":"Luis","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Centro de Bacteriologia, N\u00facleo de Doen\u00e7as Ent\u00e9ricas, Instituto Adolfo Lutz, Avenida Dr. Arnaldo, 355, S\u00e3o Paulo 01246-000, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamila","family":"Nunes","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vaniky","family":"Marques","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3470-5706","authenticated-orcid":false,"given":"Waldir","family":"Elias","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Herbert","family":"Silva","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0484-2243","authenticated-orcid":false,"given":"Bruna","family":"Caetano","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0068-8506","authenticated-orcid":false,"given":"Roxane","family":"Piazza","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacteriologia, Instituto Butantan, Avenida Vital Brasil, 1500, S\u00e3o Paulo 05503-900, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1016\/j.bjid.2018.10.279","article-title":"Epidemiology of pathogens causing urinary tract infections in an urban community in southern Brazil","volume":"22","author":"Reu","year":"2018","journal-title":"Braz.
