Phenol-water extracted lipopolysaccharides (LPS) from serogroups A (O-antigens 2, 12), B (4, 5, 12) and D (9, 12) were used as antigens. When compared to the tube agglutination method according to Widal employing sera from patients with verified or suspected typhoid \u2013 or paratyphoid fever and from healthy controls it was found that ELISA (i) correlated significantly with the Widal reaction, (ii) was up to 100-fold more sensitive, and (iii) showed a greater reproducibility.<\/jats:p>","DOI":"10.1159\/000231336","type":"journal-article","created":{"date-parts":[[2009,7,28]],"date-time":"2009-07-28T02:24:43Z","timestamp":1248747883000},"page":"485-494","source":"Crossref","is-referenced-by-count":42,"title":["Quantitation of Salmonella O-Antibodies in Human Sera by Enzyme-Linked Immunosorbent Assay (ELISA)"],"prefix":"10.1159","author":[{"given":"Hans E.","family":"Carlsson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alf A.","family":"Lindberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sten","family":"Hammarstr\u00f6m","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c5ke","family":"Ljunggren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,7,23]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/231336","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000231336","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T10:12:17Z","timestamp":1777630337000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000231336"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,7,23]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000231336","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,7,23]]}}}
