The most common\n Salmonella<\/jats:italic>\n isolates were\n Salmonella enterica<\/jats:italic>\n serovar Typhimurium (44.6%),\n S. enterica<\/jats:italic>\n serovar Enteritidis (33.4 %),\n S. enterica<\/jats:italic>\n serovar Infantis (3.2 %),\n S. enterica<\/jats:italic>\n serovar Typhi (1.5%), and\n S. enterica<\/jats:italic>\n serovar Bovismorbificans (1.5%). The other serovars accounted for less than 1% each. Our data show a high resistance to ampicillin, tetracycline, and chloramphenicol. The isolates were pansensitive (53.5%), resistant to one antimicrobial agent (10.5%), resistant to two antimicrobial agents (22.1%), resistant to three antimicrobial agents (10.8%), and to four antimicrobial agents (2.7%). Resistance to more than four antibiotics was observed in 0.5% of strains. The presence of ESBL was found in only one strain of\n S. enterica<\/jats:italic>\n serovar Bovismorbificans. The CTX-M-1 type-producing strain was identified by isoelectric focusing and molecular analysis. Results were consistent with the presence of a pI 8.6 ESBL active on cefotaxime, ceftazidime, cefepime, and aztreonam. Mating experiments showed that the CTX-M-1 determinant was transferable. To the best of our knowledge, this is the first report of CTX\u2013M-1 type ESBL in\n Salmonella<\/jats:italic>\n serovar Bovismorbificans.\n <\/jats:p>","DOI":"10.1089\/mdr.2007.683","type":"journal-article","created":{"date-parts":[[2007,7,25]],"date-time":"2007-07-25T09:17:41Z","timestamp":1185355061000},"page":"124-129","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence, Antimicrobial Resistance, and Extended-Spectrum\n \u03b2<\/i>\n -Lactamases Characterization of\n Salmonella<\/i>\n Isolates in Apulia, Southern Italy (2001\u20132005)"],"prefix":"10.1177","volume":"13","author":[{"given":"Rosa","family":"Monno","sequence":"first","affiliation":[{"name":"Department of Internal Medicine and Public Health, University of Bari, I 70124 Bari, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caterina","family":"Rizzo","sequence":"additional","affiliation":[{"name":"Department of Pharmacobiological Sciences, University of Bari, I 70124 Bari, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danila","family":"De Vito","sequence":"additional","affiliation":[{"name":"Department of Odontostomatology and Surgery, University of Bari, I 70124 Bari, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabetta","family":"Nucleo","sequence":"additional","affiliation":[{"name":"Department of Morphological, Eidological and Clinical Sciences, University of Pavia, I-27100 Pavia, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberta","family":"Migliavacca","sequence":"additional","affiliation":[{"name":"Department of Morphological, Eidological and Clinical Sciences, University of Pavia, I-27100 Pavia, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Pagani","sequence":"additional","affiliation":[{"name":"Department of Morphological, Eidological and Clinical Sciences, University of Pavia, I-27100 Pavia, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Rizzo","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Public Health, University of Bari, I 70124 Bari, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2007,6]]},"container-title":["Microbial Drug Resistance"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/mdr.2007.683","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1089\/mdr.2007.683","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T20:23:57Z","timestamp":1777667037000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.1089\/mdr.2007.683"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,6]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2007,6]]}},"alternative-id":["10.1089\/mdr.2007.683"],"URL":"https:\/\/doi.org\/10.1089\/mdr.2007.683","relation":{},"ISSN":["1076-6294","1931-8448"],"issn-type":[{"value":"1076-6294","type":"print"},{"value":"1931-8448","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,6]]}}}
