The serological reactivity of the preparation was tested against a total of 41 sera from proven cases of human leptospirosis and 27 from proven cases of animal leptospirosis. The sensitized, freeze-dried red cells appeared to be a sensitive reagent for the detection of leptospiral antibodies by haemagglutination. The use of this reagent as a screening test for leptospiral diagnosis is discussed. In the reported haemagglutination test on human and rabbit antisera the findings suggested that only IgM (19S) antibodies took part in the reaction.<\/jats:p>","DOI":"10.1136\/jcp.26.1.7","type":"journal-article","created":{"date-parts":[[2007,6,9]],"date-time":"2007-06-09T00:50:46Z","timestamp":1181350246000},"page":"7-16","source":"Crossref","is-referenced-by-count":22,"title":["Genus-specific leptospiral antigen and its possible use in laboratory diagnosis"],"prefix":"10.1136","volume":"26","author":[{"given":"A.","family":"Palit","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Gulasekharam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1973,1,1]]},"reference":[{"key":"ref_1","first-page":"39","article-title":"Studies on mouse antibodies.
