Water used for irrigation of fresh produce can transmit such resistant bacteria directly to edible plant parts. We screened ESBL-producing Escherichia coli, Enterobacter cloacae, and Citrobacter freundii isolated from irrigation water for their potential to transmit resistance to antibiotic-susceptible E. coli. All strains were genome-sequenced and tested in vitro for transmission of resistance to third-generation cephalosporins on solid agar as well as in liquid culture. Of the 19 screened isolates, five ESBL-producing E. coli were able to transfer resistance with different efficiency to susceptible recipient E. coli. Transconjugant strains were sequenced for detection of transferred antibiotic resistance genes (ARGs) and compared to the known ARG pattern of their respective donors. Additionally, phenotypic resistance patterns were obtained for both transconjugant and corresponding donor strains, confirming ESBL-producing phenotypes of all obtained transconjugants.<\/jats:p>","DOI":"10.3390\/microorganisms8070978","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T09:04:59Z","timestamp":1593507899000},"page":"978","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Transferable Extended-Spectrum \u03b2-Lactamase (ESBL) Plasmids in Enterobacteriaceae from Irrigation Water"],"prefix":"10.3390","volume":"8","author":[{"given":"Maria-Theresia","family":"Gekenidis","sequence":"first","affiliation":[{"name":"Microbiological Food Safety, Agroscope, 8820 W\u00e4denswil, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita","family":"Kl\u00e4ui","sequence":"additional","affiliation":[{"name":"Microbiological Food Safety, Agroscope, 3003 Liebefeld, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kornelia","family":"Smalla","sequence":"additional","affiliation":[{"name":"Institute for Epidemiology and Pathogen Diagnostics, Julius K\u00fchn-Institut\u2014Federal Research Centre for Cultivated Plants (JKI), 38104 Braunschweig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Drissner","sequence":"additional","affiliation":[{"name":"Department of Life Sciences, Albstadt-Sigmaringen University, 72488 Sigmaringen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"758","DOI":"10.1126\/science.352.6287.758","article-title":"Resistance fighters","volume":"352","author":"Kupferschmidt","year":"2016","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1146\/annurev-genet-102209-163517","article-title":"The genomic enzymology of antibiotic resistance","volume":"44","author":"Morar","year":"2010","journal-title":"Annu.
