Diagnosis is based on the observation of budding<jats:named-content content-type=\"genus-species\">P. brasiliensis<\/jats:named-content>yeast in clinical specimens from patients; however, the sensitivity of the visualization of fungi is low, indicating that serological tests are used for early diagnosis. The double-immunodiffusion test (ID) is the \u201cgold standard\u201d test for serology in PCM, although the execution of this test requires the availability of laboratorial infrastructure. We report the improved performance of a latex agglutination test (LAT) by pretreating 30 serum samples from PCM patients and 71 controls (histoplasmosis and aspergillosis patients, patients with bacterial infections, and normal human sera) with a dilution buffer incubated at 37\u00b0C for 30 min. The sensitivity and specificity of the LAT test in the nonpretreated samples were 73% and 79%, respectively. However, when samples were pretreated, the sensitivity and specificity of the test increased to 90%. In this study, we did not observe cross-reactivity with histoplasmosis patient sera, but some reactions to sera from patients with aspergillosis and bacterial infections were noted. Normal human sera were not reactive in our tests. These results indicate the need for the elimination of heterologous reactions so that we can adequately use this method for screening cases of PCM.<\/jats:p>","DOI":"10.1128\/cvi.05274-11","type":"journal-article","created":{"date-parts":[[2011,12,29]],"date-time":"2011-12-29T02:17:33Z","timestamp":1325125053000},"page":"386-390","source":"Crossref","is-referenced-by-count":5,"title":["Effects of Pretreating Serum Samples on the Performance of a Latex Agglutination Test for Serodiagnosis of Paracoccidioidomycosis"],"prefix":"10.1128","volume":"19","author":[{"given":"Fab\u00edola","family":"Silveira-Gomes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia Helena","family":"Marques-da-Silva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","published-online":{"date-parts":[[2011,12,28]]},"reference":[{"key":"key20180919073558_B1","first-page":"235","article-title":"Fast visualization of protein bands by impregnation in potassium permanganate and silver nitrate","volume-title":"Electrophoresis 82","author":"Ansorge","year":"1983"},{"key":"key20180919073558_B2","doi-asserted-by":"crossref","first-page":"336","DOI":"10.1080\/13693780802607400","article-title":"Evaluation of three commercial latex agglutination kits and a commercial enzyme immunoassay for the detection of cryptococcal antigen","volume":"47","author":"Babady","year":"2009","journal-title":"Med.
