Similar results (93% and 54% positive sera respectively) were obtained for specific IgM as assessed by the enzyme-linked immunosorbent assay (ELISA) using lipopolysaccharide of<jats:italic>S. typhi<\/jats:italic>as antigen (median relative titer: 0.32 and 0.21 respectively). In contrast, specific IgG at significant concentrations were found in only 69% of the Austrian (median relative titer: 0.16) but 88% of the Hong Kong sera (median relative titer: 0.71). The (IgM-detecting) microagglutination test may be sufficiently diagnostic for typhoid fever in nonendemic areas such as Austria. In endemic regions like Hong Kong, however, tests indicative for early specific IgG are indispensable for serological diagnosis of the disease. The ELISA proved useful and is an example for such tests.<\/jats:p>","DOI":"10.1017\/s0195941700062779","type":"journal-article","created":{"date-parts":[[2016,8,3]],"date-time":"2016-08-03T04:54:38Z","timestamp":1470200078000},"page":"110-114","source":"Crossref","is-referenced-by-count":3,"title":["Antibody Response to Somatic Antigen of<i>Salmonella typhi<\/i>in Areas Endemic and Non-Endemic for Typhoid Fever"],"prefix":"10.1017","volume":"6","author":[{"given":"Alexander","family":"Hirschl","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerold","family":"Stanek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred L.","family":"Rotter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pak Y.","family":"Chau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adolf H.","family":"Niemetz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2015,1,2]]},"reference":[{"key":"S0195941700062779_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(71)90056-0"},{"key":"S0195941700062779_ref019","doi-asserted-by":"crossref","first-page":"703","DOI":"10.1128\/iai.6.5.703-708.1972","article-title":"Titration of antibodies to salmonella O antigens by enzyme linked immunosorbent assay","volume":"6","author":"Carlsson","year":"1972","journal-title":"Infect Immun"},{"key":"S0195941700062779_ref016","doi-asserted-by":"crossref","first-page":"334","DOI":"10.4049\/jimmunol.96.2.334","article-title":"Weight estimates of rabbit anti-human serum albumin based on antigen binding and precipitin analyses: Specific haemagglutinating activities of 7S and 19S components","volume":"96","author":"Osler","year":"1966","journal-title":"J Immunol"},{"key":"S0195941700062779_ref013","first-page":"515","article-title":"Antibody response to the lipopolysaccharide and protein antigens of S. typhi during typhoid infection.
