Antibiotic-resistance genes were recorded at high rates in &lt;i&gt;E. coli&lt;\/i&gt; isolates, especially genes blaampC (98.52%), tetA (50.74%), sulII (34.48%), qnrA (20.69%), and aadA1 (20.69%). Moreover, 55.67% of these &lt;i&gt;E. coli&lt;\/i&gt; isolates harbored multiple antibiotic-resistance genes. Among heavy-metal-resistance genes, the gene czcD encoding for resistance to cobalt, zinc, and cadmium was the most prevalent (59.11%). In addition, the most frequent virulent gene was stx1 (15.27%), followed by gene stx2 (6.90%), eae, and hlyA (1.48%).\n&lt;b&gt;Conclusion:&lt;\/b&gt; These results revealed that goats were a natural reservoir of pathogenic &lt;i&gt;E. coli&lt;\/i&gt; serotypes, which could cause severe diseases in animals and humans. Moreover, these &lt;i&gt;E. coli&lt;\/i&gt; isolates showed a high ability to resist diverse antibiotics. Thus, managing the prevalence of pathogenic &lt;i&gt;E. coli&lt;\/i&gt; is essential for protecting public health in the Mekong Delta.<\/jats:p>","DOI":"10.5455\/javar.2025.l908","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T23:30:41Z","timestamp":1754091041000},"page":"420","source":"Crossref","is-referenced-by-count":2,"title":["Antibiotic resistance and pathogenicity of Shiga-toxin-producing &lt;i&gt;Escherichia coli&lt;\/i&gt; (STEC) and non-STEC isolated from goats in the Mekong Delta, Vietnam"],"prefix":"10.5455","volume":"12","author":[{"given":"Thuan","family":"Nguyen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trung","family":"Truong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toan","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duy","family":"Tran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thu","family":"Dang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binh","family":"Tran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Journal of Advanced Veterinary and Animal Research"],"original-title":[],"link":[{"URL":"https:\/\/www.bibliomed.org\/fulltextpdf.php?mno=240717","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:02:43Z","timestamp":1791482563000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bibliomed.org\/?mno=240717"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.5455\/javar.2025.l908","relation":{},"ISSN":["2311-7710"],"issn-type":[{"value":"2311-7710","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
