Similarities included the observation that assays using both antigens demonstrated an increasing prevalence of IgG4 antibodies in the transmigrant population with increasing exposure to the infection, and by six years living in the area, antibody prevalence was similar to that of life-long residents. With regards to differences, of significance is the demonstration of similar antibody prevalence in adults and children by BmR1 dipstick whereas by SWA-ELISA the antibody prevalence in adults was higher than in children.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Conclusions<\/jats:title>\n                        <jats:p>Results and conclusions made from investigations of prevalence of anti-filarial IgG4 antibody in a population would be affected by the assay employed in the study.<\/jats:p>\n                     <\/jats:sec>","DOI":"10.1186\/1475-2883-3-8","type":"journal-article","created":{"date-parts":[[2004,9,1]],"date-time":"2004-09-01T06:23:14Z","timestamp":1094019794000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparison of IgG4 assays using whole parasite extract and BmR1 recombinant antigen in determining antibody prevalence in brugian filariasis"],"prefix":"10.1186","volume":"3","author":[{"given":"Rahmah","family":"Noordin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sitti","family":"Wahyuni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andarias","family":"Mangali","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lim Boon","family":"Huat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Yazdanbakhsh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erliyani","family":"Sartono","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2004,8,12]]},"reference":[{"key":"35_CR1","first-page":"3","volume-title":"Lymphatic Filariasis: Reasons for Hope","author":"World Health Organization","year":"1998","unstructured":"World Health Organization: Lymphatic Filariasis: Reasons for Hope. 1998, 3-5.
