This study aims to estimate the prevalence of diarrhoeagenic <jats:italic>Escherichia coli<\/jats:italic> (DEC) and <jats:italic>Salmonella<\/jats:italic> spp. with zoonotic potential in urban slum environments. We trapped rats between April and June 2018 in Salvador, Brazil. We collected rectal swabs from <jats:italic>Rattus<\/jats:italic> spp., and cultured for <jats:italic>E. coli<\/jats:italic> and <jats:italic>Salmonella<\/jats:italic> spp., and screened <jats:italic>E. coli<\/jats:italic> isolates by polymerase chain reaction to identify pathotypes. <jats:italic>E. coli<\/jats:italic> were found in 70% of <jats:italic>Rattus norvegicus<\/jats:italic> and were found in four <jats:italic>Rattus rattus<\/jats:italic>. DEC were isolated in 31.3% of the 67 brown rats (<jats:italic>R. norvegicus<\/jats:italic>). The pathotypes detected more frequently were shiga toxin <jats:italic>E. coli<\/jats:italic> in 11.9%, followed by atypical enteropathogenic <jats:italic>E. coli<\/jats:italic> in 10.4% and enteroinvasive <jats:italic>E. coli<\/jats:italic> in 4.5%. From the five black rats (<jats:italic>R. rattus<\/jats:italic>), two presented DEC. <jats:italic>Salmonella enterica<\/jats:italic> was found in only one (1.4%) of 67 <jats:italic>R. norvegicus<\/jats:italic>. Our findings indicate that both <jats:italic>R. norvegicus<\/jats:italic> and <jats:italic>R. rattus<\/jats:italic> are host of DEC and, at lower prevalence, <jats:italic>S. enterica<\/jats:italic>, highlighting the importance of rodents as potential sources of pathogenic agents for humans.<\/jats:p>","DOI":"10.1017\/s095026882000285x","type":"journal-article","created":{"date-parts":[[2020,11,20]],"date-time":"2020-11-20T04:34:03Z","timestamp":1605846843000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence of Diarrheagenic <i>Escherichia coli<\/i> (DEC) and <i>Salmonella<\/i> spp. with zoonotic potential in urban rats in Salvador, Brazil"],"prefix":"10.1017","volume":"149","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6234-332X","authenticated-orcid":false,"given":"C.","family":"Pimentel Sobrinho","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Lima Godoi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Neves Souza","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0490-4395","authenticated-orcid":false,"given":"C.","family":"Graco Zeppelini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Espirito Santo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Carvalho Santiago","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Sady Alves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Khalil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Carvalho Pereira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Hanzen Pinna","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Begon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Machado Cordeiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Neves Reis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Costa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2020,11,20]]},"reference":[{"key":"S095026882000285X_ref1","doi-asserted-by":"publisher","DOI":"10.1089\/vbz.2012.1195"},{"key":"S095026882000285X_ref8","doi-asserted-by":"publisher","DOI":"10.4061\/2011\/686923"},{"key":"S095026882000285X_ref2","doi-asserted-by":"publisher","DOI":"10.1089\/vbz.2013.1378"},{"key":"S095026882000285X_ref4","doi-asserted-by":"publisher","DOI":"10.7589\/2014-09-242"},{"key":"S095026882000285X_ref7","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268816002259"},{"key":"S095026882000285X_ref3","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2672.1999.00549.x"},{"key":"S095026882000285X_ref9","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0050331"},{"key":"S095026882000285X_ref5","doi-asserted-by":"publisher","DOI":"10.1017\/S095026880700948X"},{"key":"S095026882000285X_ref6","unstructured":"6.
