Cephalosporin resistance in <jats:italic>Salmonella<\/jats:italic> species is mainly due to the production of extended-spectrum <jats:italic>\u03b2<\/jats:italic>-lactamases (ESBLs). The majority of ESBLs in <jats:italic>Salmonella enterica<\/jats:italic> serovar Typhi are derivatives of the TEM, SHV, and CTX-M <jats:italic>\u03b2<\/jats:italic>-lactamase families. Of these, CTX-M appears to be predominant. This paper discusses the detection and molecular characterization of an ESBL-producing <jats:italic>Salmonella enterica<\/jats:italic> serovar Typhi strain isolated from a patient who was admitted to a private hospital in Sri Lanka. The three main types of <jats:italic>\u03b2<\/jats:italic>-lactamases such as TEM, SHV, and CTX-M were identified in this isolate. This case report from Sri Lanka contributes to the knowledge of the increasingly reported cases of typhoid fever due to <jats:italic>Salmonella enterica<\/jats:italic> serovar Typhi resistant to <jats:italic>\u03b2<\/jats:italic>-lactamase by ESBL production.<\/jats:p>","DOI":"10.1155\/2018\/4610246","type":"journal-article","created":{"date-parts":[[2018,2,15]],"date-time":"2018-02-15T23:31:24Z","timestamp":1518737484000},"page":"1-5","source":"Crossref","is-referenced-by-count":10,"title":["Typhoid Fever due to Extended Spectrum <i>\u03b2<\/i>-Lactamase-Producing <i>Salmonella enterica<\/i> Serovar Typhi: A Case Report and Literature Review"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7573-6205","authenticated-orcid":true,"given":"Abdul Azeez","family":"Ahamed Riyaaz","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Dr. Neville Fernando Teaching Hospital, Malabe, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8905-9882","authenticated-orcid":true,"given":"Vindya","family":"Perera","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Medicine, South Asian Institute of Technology and Medicine, Malabe, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabaratnam","family":"Sivakumaran","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Dr. Neville Fernando Teaching Hospital, Malabe, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nelun","family":"de Silva","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Faculty of Medicine, South Asian Institute of Technology and Medicine, Malabe, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.3201\/eid2004.131536"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1086\/587894"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/qco.0b013e32830f453a"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.2471\/blt.06.039818"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.1229"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.3201\/eid1509.090567"},{"year":"2012","key":"7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.7860\/jcdr\/2013\/4619.2734"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkp498"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.42.12.5917-5920.2004"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.18203\/2349-3933.ijam20161107"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1128\/aac.49.4.1662-1663.2005"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.4103\/0255-0857.58730"},{"key":"14","first-page":"431","volume":"133","year":"2011","journal-title":"Indian Journal of Medical Research"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1086\/319610"},{"issue":"5","key":"16","first-page":"417","volume":"126","year":"2007","journal-title":"Indian Journal of Medical Research"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.47509-0"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1111\/j.1574-6976.2010.00222.x"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.00676-08"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1056\/nejmra020201"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.044065-0"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.068486-0"}],"container-title":["Case Reports in Infectious Diseases"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/criid\/2018\/4610246.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criid\/2018\/4610246.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/criid\/2018\/4610246.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,19]],"date-time":"2020-05-19T01:08:27Z","timestamp":1589850507000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/criid\/2018\/4610246\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":22,"alternative-id":["4610246","4610246"],"URL":"https:\/\/doi.org\/10.1155\/2018\/4610246","relation":{},"ISSN":["2090-6625","2090-6633"],"issn-type":[{"type":"print","value":"2090-6625"},{"type":"electronic","value":"2090-6633"}],"subject":[],"published":{"date-parts":[[2018]]}}}
