Abstract

We report the expression in Escherichia coli of a 27-kDa antigenic protein from Paracoccidioides brasiliensis. When analyzed by immunoblotting, this recombinant antigenic protein was recognized by antibodies present in the sera of 40 of the 44 paracoccidioidomycosis patients studied. No cross-reactions were observed with sera from patients with other mycoses (histoplasmosis, aspergillosis, cryptococcosis, sporotrichosis, and chromoblastomycosis) or with tuberculosis.

摘要

我们报道了巴西副球孢子菌一种27 kDa抗原蛋白在大肠杆菌中的表达。通过免疫印迹分析,在所研究的44例副球孢子菌病患者中,有40例患者血清中的抗体可识别这种重组抗原蛋白。未观察到与其他真菌病(组织胞浆菌病、曲霉病、隐球菌病、孢子丝菌病和成芽细胞菌病)患者的血清或结核病患者的血清发生交叉反应。
