Resulting isolates were characterised\u00a0by serogrouping, serotyping, antimicrobial susceptibility testing and detection of extended-spectrum \u03b2-lactamase (ESBL) production. Antibiotic resistance genes and integrons were\u00a0identified by polymerase chain reaction (PCR).Results: The detection rates of Salmonella were 60%, 64% and 62% in chicken parts, skin, and\u00a0faeces, respectively, whereas the egg yolks and eggshells were uniformly negative. Salmonella\u00a0Kentucky and S. Enteritidis serotypes comprised 43.6% and 2.6% of the isolates, respectively,\u00a0whilst S. Typhimurium was absent. Variable resistance rates were observed against 16\u00a0antibiotics; 97% were resistant to sulfamethoxazole, 96% to nalidixic acid and tetracycline and\u00a076% to ampicillin. Multidrug resistance was detected in 82% (64\/78) of the isolates and ESBL\u00a0production was detected in 8% (6\/78). The \u03b2-lactamase blaTEM-1 gene was detected in 57.6% and blaSHV-1 in 6.8% of the isolates, whilst the blaOXA gene was absent. The sul1gene was\u00a0detected in 97.3% and the sul2 gene in 5.3% of the isolates. Sixty-four of the 78 isolates (82%)\u00a0were positive for the integrase gene (int I) from class 1 integrons, whilst int II was absent.Conclusion: This study reveals the presence of an alarming number of multidrug-resistant\u00a0Salmonella isolates in the local poultry markets in Cairo. The high levels of drug resistance\u00a0suggest an emerging problem that could impact negatively on efforts to prevent and treat\u00a0poultry and poultry-transmitted human diseases in Egypt.<\/jats:p>","DOI":"10.4102\/ajlm.v4i1.158","type":"journal-article","created":{"date-parts":[[2015,5,14]],"date-time":"2015-05-14T14:17:30Z","timestamp":1431613050000},"source":"Crossref","is-referenced-by-count":30,"title":["Genetic characterisation of multidrug-resistant &lt;i&gt;Salmonella enterica&lt;\/i&gt; serotypes isolated from poultry in Cairo, Egypt"],"prefix":"10.4102","volume":"4","author":[{"given":"Mohammed","family":"Abdel-Maksoud","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rania","family":"Abdel-Khalek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atef","family":"El-Gendy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rawia F.","family":"Gamal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hemmat M.","family":"Abdelhady","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brent L.","family":"House","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2015,5,13]]},"reference":[{"key":"ref0001","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dki365"},{"key":"ref0002","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkh325"},{"key":"ref0003","doi-asserted-by":"publisher","DOI":"10.1086\/424570"},{"key":"ref0004","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.48.5.1916-1917.2004"},{"key":"ref0005","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.18.4.657-686.2005"},{"key":"ref0006","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.44.8.2034-2038.2000"},{"key":"ref0007","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijantimicag.2004.01.010"},{"issue":"1","key":"ref0008","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.femsim.2004.10.007","volume":"43","author":"Fluit","year":"2005","journal-title":"Towards more virulent and antibiotic-resistant Salmonella?
