Disease Introduction MechanismParacoccidioidomycosis (PCM), the major systemic mycosis in Latin America, is caused by the thermally dimorphic fungus Paracoccidioides brasiliensis (Pb). The infection is acquired by inhalation of airborne propagules produced by the fungal mycelium form, which then change into the pathogenic yeast form when at core body temperature. The yeast forms in the mammalian host can be eliminated by immune competent cells or disseminate to tissues by the lymphatic and hematogenous route. After infection there are no immediate signs or symptoms of the disease, characterizing silent PCM but the host develops a specific immune response against fungal antigens which can be detected by a skin test. In endemic areas, up to 60% of asymptomatic individuals may be skin test positive.
