Besides <jats:italic>\u03b2<\/jats:italic>-lactams, quinolones and aminoglycosides are the major antibiotics against <jats:italic>E. coli.<\/jats:italic> In the present study, we have investigated the presence of plasmid-mediated quinolone resistance (PMQR) and aminoglycoside resistance genes in <jats:italic>E. coli<\/jats:italic> isolated from a major river of northern India. Our results revealed that majority of the strains were phenotypically susceptible for fluoroquinolones and some aminoglycosides like amikacin, netilmicin, tobramycin and gentamicin. However, 16.39% of the strains were resistant for streptomycin, 8.19% for kanamycin and 3.30% for gentamicin. Of the various PMQR genes investigated, only <jats:italic>qnrS1<\/jats:italic> was present in 24.59% of the strains along with IS<jats:italic>Ecl2<\/jats:italic>. Aminoglycoside-resistance genes like <jats:italic>strA-strB<\/jats:italic> were found to be present in 16.39%, <jats:italic>aphA1<\/jats:italic> in 8.19% and <jats:italic>aacC<\/jats:italic>2 in only 3.30% of the strains. Though, no co-relation was observed between phenotypic resistance for fluorquinolones and presence of PMQR genes, phenotypic resistance for streptomycin, kanamycin and gentamicin exactly co-related with the presence of the genes <jats:italic>strA-strB<\/jats:italic>, <jats:italic>aphA1<\/jats:italic> and <jats:italic>aacC2<\/jats:italic>, respectively. Moreover, all the AMR genes discerned in aquatic <jats:italic>E. coli<\/jats:italic> were found to be situated on conjugative plasmids and, thus easily transferrable. Our study accentuates the importance of routine surveillance of urban rivers to curtail the spread of AMR genes in aquatic pathogens.<\/jats:p>","DOI":"10.1017\/s095026882200053x","type":"journal-article","created":{"date-parts":[[2022,3,28]],"date-time":"2022-03-28T10:43:37Z","timestamp":1648464217000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":8,"title":["Public health implications of plasmid-mediated quinolone and aminoglycoside resistance genes in <i>Escherichia coli<\/i> inhabiting a major anthropogenic river of India"],"prefix":"10.1017","volume":"150","author":[{"given":"Nambram Somendro","family":"Singh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0851-6434","authenticated-orcid":false,"given":"Neelja","family":"Singhal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7936-9892","authenticated-orcid":false,"given":"Manish","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jugsharan Singh","family":"Virdi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2022,3,28]]},"reference":[{"key":"S095026882200053X_ref20","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-015-5609-x"},{"key":"S095026882200053X_ref44","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-017-8760-8"},{"key":"S095026882200053X_ref7","doi-asserted-by":"publisher","DOI":"10.1186\/s12941-016-0174-9"},{"key":"S095026882200053X_ref32","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.66.10.4555-4558.2000"},{"key":"S095026882200053X_ref26","doi-asserted-by":"publisher","DOI":"10.1289\/ehp.9770"},{"key":"S095026882200053X_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijheh.2018.11.002"},{"key":"S095026882200053X_ref25","doi-asserted-by":"publisher","DOI":"10.1007\/s00284-020-02107-y"},{"key":"S095026882200053X_ref45","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.01037-16"},{"key":"S095026882200053X_ref52","doi-asserted-by":"publisher","DOI":"10.1089\/mdr.2012.0210"},{"key":"S095026882200053X_ref49","doi-asserted-by":"publisher","DOI":"10.1128\/microbiolspec.ARBA-0026-2017"},{"key":"S095026882200053X_ref40","doi-asserted-by":"publisher","DOI":"10.1016\/j.watres.2014.11.021"},{"key":"S095026882200053X_ref53","doi-asserted-by":"publisher","DOI":"10.1111\/jam.12691"},{"key":"S095026882200053X_ref56","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.00997-08"},{"key":"S095026882200053X_ref57","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.06191-11"},{"key":"S095026882200053X_ref5","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkg222"},{"key":"S095026882200053X_ref3","doi-asserted-by":"publisher","DOI":"10.1179\/2047773215Y.0000000030"},{"key":"S095026882200053X_ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecoenv.2016.10.031"},{"key":"S095026882200053X_ref38","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2012.00024"},{"key":"S095026882200053X_ref34","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.42.3.1089-1094.2004"},{"key":"S095026882200053X_ref11","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkr548"},{"key":"S095026882200053X_ref47","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.06066-11"},{"key":"S095026882200053X_ref43","doi-asserted-by":"publisher","DOI":"10.2323\/jgam.2018.02.003"},{"key":"S095026882200053X_ref8","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.25.13991"},{"key":"S095026882200053X_ref17","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.48.10.3996-4001.2004"},{"key":"S095026882200053X_ref37","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.00638-08"},{"key":"S095026882200053X_ref21","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2018.00382"},{"key":"S095026882200053X_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.diagmicrobio.2009.12.004"},{"key":"S095026882200053X_ref9","doi-asserted-by":"publisher","DOI":"10.1128\/microbiolspec.PLAS-0006-2013"},{"key":"S095026882200053X_ref14","doi-asserted-by":"publisher","DOI":"10.1093\/femsec\/fiv015"},{"key":"S095026882200053X_ref55","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.01400-08"},{"key":"S095026882200053X_ref29","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.00359-12"},{"key":"S095026882200053X_ref51","doi-asserted-by":"publisher","DOI":"10.1016\/j.drup.2010.08.003"},{"key":"S095026882200053X_ref1","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.00698-13"},{"key":"S095026882200053X_ref4","doi-asserted-by":"publisher","DOI":"10.1017\/gheg.2017.4"},{"key":"S095026882200053X_ref33","volume-title":"Performance Standards for Antimicrobial Susceptibility Testing; Approved Standard \u2013 28th ed.
