The aim of this study was to examine the fate of sulfonamide-resistant fecal bacteria (<i>E</i>. <i>coli</i>) in an estuary ecosystem and to explore the role and contribution of environmental factors in this process. The prevalence of sulfonamide-resistance status of <i>E</i>. <i>coli</i> was analyzed over different seasons in two estuary systems. Environmental factors and disturbance indices of anthropogenic activities were evaluated by detecting antibiotic concentrations, heavy metal abundance and other physicochemical parameters. The abundances of antibiotic-resistant <i>E</i>. <i>coli</i> were significantly attenuated during land-sea migration suggesting that estuary environments play a natural mitigation role in the contamination of freshwaters by antibiotic-resistant <i>E</i>. <i>coli</i>. Additionally, environmental factors and disturbance indices of anthropogenic activities significantly correlated with the distribution and migration of antibiotic-resistant <i>E</i>. <i>coli</i> in the estuaries. Lastly, simulation experiments suggested differential adaptability between antibiotic-resistant and non-resistant <i>E</i>. <i>coli</i> towards environmental changes in estuary environments. Meanwhile, our results indicate that low concentrations of antibiotics will not increase the competitive advantage of resistant <i>E</i>. <i>coli</i> in estuaries.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The effect of environmental factors and migration dynamics on the prevalence of antibiotic-resistant <i>Escherichia coli</i> in estuary environments","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:02.817030","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2018-02-08","DateCreate":"2018-02-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000423426500001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-018-20077-x"},"refs":null,"anarec":{"AnaID":292640,"PubliDate":2018,"Pagination":"9 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
