Earlier studies have shown that the enzyme immunoassay improves the sensitivity of antibody detection for the diagnosis of blastomycosis. Microplates coated with the<jats:named-content content-type=\"genus-species\">B. dermatitidis<\/jats:named-content>surface protein BAD-1 were used for testing sera from patients with proven blastomycosis or histoplasmosis and controls. Semiquantification was accomplished by using standards containing human anti-<jats:named-content content-type=\"genus-species\">B. dermatitidis<\/jats:named-content>antibodies. The antibodies were detected in 87.8% of the patients with blastomycosis by the enzyme immunoassay compared to 15.0% by immunodiffusion. The specificities were 99.2% for patients with nonfungal infections and healthy subjects and 94.0% for patients with histoplasmosis. The results were highly reproducible on repeat testing. When combined with antigen testing, antibody testing improved the sensitivity from 87.8% to 97.6%. Enzyme immunoassay detection of antibodies against BAD-1 is highly specific, has greatly improved sensitivity over immunodiffusion, and may identify cases with negative results by antigen testing. This assay has the potential to aid in the diagnosis of blastomycosis.<\/jats:p>","DOI":"10.1128\/cvi.00597-13","type":"journal-article","created":{"date-parts":[[2013,11,28]],"date-time":"2013-11-28T02:38:14Z","timestamp":1385606294000},"page":"143-146","source":"Crossref","is-referenced-by-count":77,"title":["Development of a Highly Sensitive and Specific Blastomycosis Antibody Enzyme Immunoassay Using Blastomyces dermatitidis Surface Protein BAD-1"],"prefix":"10.1128","volume":"21","author":[{"given":"Sarah M.","family":"Richer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melinda L.","family":"Smedema","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle M.","family":"Durkin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.
