Abstract

The objective of this study was to determine the immunochemical profile of three exoantigen preparations obtained from clinical samples of Paracoccidioides lutzii from the state of Mato Grosso, Brazil. The exoantigens were prepared according to a protocol standardized by Camargo et al. and their immunochemical profiles were analyzed using SDS-PAGE. The observed protein bands exhibited molecular weights of 20, 30, and 130 kDa.  The 130 kDa glycoprotein was detected in all three preparations. The detection of this high-molecular-weight protein suggests a distinct immunochemical profile. These differences may help to explain the false negative reactions obtained when using the antigen from P. brasiliensis reference strain B-339. This information is essential for increasing the specificity of serological tests used to monitor the prognosis of patients with paracoccidioidomycosis.
