The collection was further characterized for extended-spectrum\ncephalosporin, aminoglycoside, and tetracycline resistance markers. Multidrug resistant (MDR) isolates were\nfurther investigated for class 1 integrons and were evaluated for the presence of conjugative plasmids along\nwith a determination of the incompatibility group by polymerase chain reaction (PCR). Antibiogram analysis\nshowed that the incidence rate of ceftiofur resistance was moderately high (15%). A similar level of resistance\nto neomycin and oxytetracycline (11% and 10%, respectively) was also observed. There was a high\nprevalence of gene cassettes as part of one or more class 1 integrons (61%), many of which contained determinants\nthat contributed to the resistance profile. Class 1 integrons identified in MDR\n Salmonella enterica<\/jats:italic>\n serotypes Typhimurium and Anatum isolates were characterized. Sequencing identified several incomplete\nopen reading frames (ORFs) as part of a gene cassette (\n bla<\/jats:italic>\n -\n \n imp-13<\/jats:italic>\n <\/jats:sub>\n ,\n dfr7, blr1088<\/jats:italic>\n , and\n aac8<\/jats:italic>\n ) along with a complete\ngene cassette (\n bla<\/jats:italic>\n -\n oxa2<\/jats:sub>\n ) in each case. A mosaic of gene cassettes was identical in the two\n Salmonella<\/jats:italic>\n serotypes. These integrons were located to a conjugative replicon. Plasmid profiling and incompatibility typing\nidentified three plasmids belonging to Inc groups A\/C, P, and W. Our study highlights the role of integrons,\ncontributing to a MDR phenotype that is capable of dissemination to other bacteria.\n <\/jats:p>","DOI":"10.1089\/mdr.2006.12.269","type":"journal-article","created":{"date-parts":[[2007,1,16]],"date-time":"2007-01-16T20:31:13Z","timestamp":1168979473000},"page":"269-277","source":"Crossref","is-referenced-by-count":33,"title":["Antimicrobial Resistance in Nontyphoidal\n Salmonella<\/i>\n from Food Sources in Colombia: Evidence for an Unusual Plasmid-Localized Class 1 Integron in Serotypes Typhimurium and Anatum"],"prefix":"10.1177","volume":"12","author":[{"given":"Rebecca","family":"O'Mahony","sequence":"first","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Quinn","sequence":"additional","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise","family":"Drudy","sequence":"additional","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ciara","family":"Walsh","sequence":"additional","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Whyte","sequence":"additional","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salim","family":"Mattar","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Biologicas del Tropico, Facultad de Medicina Veterinaria y Zootecnia, Universidad de Cordoba, Monteria, Cordoba, Colombia."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S\u00e9amus","family":"Fanning","sequence":"additional","affiliation":[{"name":"Centre for Food Safety, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin, Dublin, Ireland."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2006,12]]},"container-title":["Microbial Drug Resistance"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/mdr.2006.12.269","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/mdr.2006.12.269","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T20:23:37Z","timestamp":1777667017000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.1089\/mdr.2006.12.269"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,12]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2006,12]]}},"alternative-id":["10.1089\/mdr.2006.12.269"],"URL":"https:\/\/doi.org\/10.1089\/mdr.2006.12.269","relation":{},"ISSN":["1076-6294","1931-8448"],"issn-type":[{"value":"1076-6294","type":"print"},{"value":"1931-8448","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,12]]}}}
