Blood clot culture was positive in 18 (41%) of 44 confirmed cases and stool culture in 24 (59%) of 41. The yield from 2189 Widal clot cultures was only 0.03%. There were 68 positive results in 2258 unpaired Widal tests: 23 of them were falsely positive and 13 falsely negative, but in 11 out of 68 cases the Widal was the only positive laboratory test. It is concluded that routine clot culture is not cost effective if a sensitive blood culture method is used, and that the Widal test is useful only in selected patients.<\/jats:p>","DOI":"10.1136\/jcp.43.10.863","type":"journal-article","created":{"date-parts":[[2007,6,9]],"date-time":"2007-06-09T00:50:46Z","timestamp":1181350246000},"page":"863-865","source":"Crossref","is-referenced-by-count":15,"title":["Comparison of methods for the diagnosis of typhoid fever."],"prefix":"10.1136","volume":"43","author":[{"given":"R","family":"Duthie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G L","family":"French","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1990,10,1]]},"reference":[{"key":"ref_1","article-title":"Director ofMedical and Health Services. 1988-1989 Departmental Report","year":"1989","unstructured":"Director ofMedical and Health Services. 1988-1989 Departmental Report.
