[Paracoccidioidomycosis in Brazilian Indians of the Suruí tribe: clinical-laboratory study of 2 cases].

Paracoccidioidomycosis has been considered the most frequent endemic systemic mycosis in Latin America. Although most cases of paracoccidioidomycosis involve rural workers, this systemic fungal disease has been scarcely reported among Amerindian populations from Brazil. We report two cases of paracoccidioidomycosis in Tupi-Mondé Amerindians from Cacoal, state of Rondônia, Brazil. Both cases exhibited positive serological results by a specific immunodiffusion test only when the assay was performed with antigens obtained from the mycelial form of P. brasiliensis. The authors present a literature review of paracoccidioidomycosis in Brazilian Amerindians and discuss the need for further investigations about the impact of the antigenic diversity of P. brasiliensis from different geographic areas on the serological diagnosis of PCM.
